LED High Bay

Industrial LED high bay lights available at FactorLed

This is the page from which you order the lighting for an entire industrial building. It is not a catalogue to browse: it is where you settle what wattage you hang, with which optic and in which colour temperature, and where the order goes out with those details already decided. The job of an LED high bay is to go up high, push the luminous flux down onto the working plane and not waste half of it heating the roof structure.

Buy your industrial LED high bay direct from the manufacturer for buildings that need lighting calculated point by point

We manufacture the entire range, from the aluminium body to the electronics inside it. That changes two things about your purchase: the components are declared on every datasheet instead of hiding behind an adjective, and the same product code can be reordered seasons later without mismatched colour tones showing up along a row. If you sell, install or maintain lighting installations, that series continuity is worth more than any line on the datasheet.

With this product, wattage tells you very little. Two units of the same power distribute light very differently depending on the beam angle, the chip they use and how well the body dissipates heat. If you already have the floor dimensions and clear height, write to us at comercial@factorled.com and we will send you back the wattage, optic and number of light points before you place your order. And if you buy for resale or for a project, ask for our trade price list and work with wholesale pricing from the very first unit.

When it pays to order an industrial LED high bay and why it is the ideal high-efficiency LED light for industrial buildings and warehouses

The useful question is not what a high bay is, but at what point buying one makes financial sense. The answer comes down to a single figure: the clear height. Below four or five metres there are formats that are easier to maintain and to lay out, with less direct glare in the operator's face. Above that height the equation reverses, and the higher the light point sits, the more you need a fitting that concentrates light rather than spreading it.

What sets it apart from a ceiling light or a panel is the mounting position rather than the power: a circular finned body on top, the optic underneath and a hook, eyebolt or suspension cable to fix it to the structure. It is installed above five metres, often above ten, and from there it has to carry light down to the floor without it scattering on the way. If your roof sits in that range, this is the range you need to order.

The name changes depending on who is writing it. The manufacturer calls it a high bay luminaire on the datasheet, the installer simply calls it a high bay, a tender specification may ask for a high bay fitting, and the maintenance log may record it as a bay light. Behind all those names there is just one fitting: aluminium, optics and power electronics hanging up high.

It belongs wherever there is height and open floor space: production halls, logistics, repair workshops, cold stores, sports halls, covered car parks with high ceilings, picking areas and indoor loading bays. In industrial environments the argument is never aesthetic: lighting determines the visibility and safety of anyone manoeuvring a forklift between seven-metre racks, and it also determines how many picking errors turn up at the end of the shift. That is the saving that justifies the investment to management.

There is one more, less obvious case: partial refurbishment. A building that is extended in phases does not need its lighting redone from scratch; it needs the unit hung in the new bay to distribute light exactly like the one already installed. That is where manufacturing the range ourselves stops being a slogan and becomes a purchasing condition, because we control series continuity and colour tolerance between batches, and we can supply you with the same product code two seasons from now.

Maintenance is the other half of the calculation, and hardly anyone puts it in the spreadsheet. At nine metres, replacing a unit is nothing like changing a light bulb: you need an access platform, you have to close off the area underneath and stop work in that aisle during the job. At height, you pay so you never have to go back up. An LED high bay with generous heat dissipation and electronics rated above their operating point lasts longer than one pushed to its limit, and that difference does not show on the day you buy: it shows up in the year-three fault log.

Before ordering, it is worth writing down the site's lighting requirements: the actual clear height from the floor to the fixing point, the lux required on the working plane, the type of task carried out underneath and whether there are racks or overhead cranes that interrupt the beam. With those four figures the choice becomes simple arithmetic and the order is right first time. Without them you buy by eye and correct it later by going up on a platform, which is the expensive part. Send them to us and our technical department will return a lighting layout on plan with the wattage already decided.

How many lumens each clear height needs: the calculation that decides whether your order takes a 100W industrial LED or steps up to a 200W industrial LED

Wattage is chosen by mounting height and by the lux level the task below demands, not by habit. And that choice sets the size of your order, because it determines how many units you end up hanging from the ceiling.

The range starts at 80 W and rises through 100, 120, 140, 150, 160, 180 and 200 W. From one power level to the next, it is not only the flux that changes: so do the weight, the body diameter and the fin area needed to dissipate the heat. Choosing the right level is what stops you paying for extra light points or falling short on illuminance.

Many of the models come in a multi-wattage version, with a selector on the body itself to set 200W-150W-100W before the unit is hung. For a warehouse that grows in phases, or an installer covering several projects, that means a single product code on the shelf instead of three, less capital tied up in stock and one less mistake when picking the order.

The figure to check on the datasheet is the luminaire lumens, not the chip lumens: the latter is always higher and is not what reaches the floor. Next to it is the efficacy, which in our range sits between 160 and 200 lm/W depending on the model, and that high energy efficiency is what underpins the payback calculation for a hundred-point installation when you have to defend it in a purchasing meeting.

The quick rule for choosing the power level, always subject to calculation: at six or seven metres of clear height, the middle of the range with a wide optic covers an open floor well; from ten metres upwards the layout calls for more power and a narrower optic, because the beam has to reach the floor intact. A 200W LED high bay with a 60º optic over a narrow aisle between tall racks performs better than two half-power units with wide beams. The required level is set by the task carried out underneath, never by the square metres of floor area.

A well-written specification does not simply ask for industrial LED high bays. It asks for wattage, optic, colour temperature in kelvin and dimming type. High bay lamps that arrive on site without those four details end up being returned or wrongly positioned, and on a high-level installation you pay for that twice: in materials and in platform hours.

If you would rather we did the calculation, send us the floor dimensions, the clear height and the type of work carried out underneath. Our technical department will return the wattage, quantity and layout of light points, and with that your order is ready to go. You can also sort it out by phone on 654 777 000.

Order by datasheet, not by nickname: 100W UFO or UFO 100W, 200W UFO or UFO 200W, 150W UFO or 150W industrial LED UFO

The same fitting reaches us written in six different ways in the same month: with the wattage first, with the format first, with the two swapped around. It makes no difference. What identifies a product is not the nickname it travels under in emails, it is the datasheet, and that is where you need to look before signing off an order line.

Six lines close that order line with no margin for error: wattage, luminaire flux, beam angle, colour temperature, ingress protection rating and driver type. Add the version, fixed or dimmable, and there is nothing left to clarify by phone when the goods are on the loading bay. A badly written order line is paid for on site, not in the office, because the wrong fitting is discovered once the platform has already been hired.

The format is decided before the wattage, and it is also on the datasheet. For an open floor with the roof at a single height, the round disc wins: symmetrical distribution around the vertical axis, cones that overlap in a grid and an even lighting result between points, which is exactly what you want to light large spaces without harsh shadows. For narrow aisles and assembly lines, where you want a continuous strip of light rather than a circular pool, an elongated format works better. And where the roof is pitched or overhead cranes cut across the beam, the choice is made on the plan, not from the product list.

Every LED high bay luminaire in the range accepts three optics and one accessory that changes the result more than anything else: the 60º reflector, which attaches to the body and narrows the beam for aisles between tall racks. That accessory is ordered with the unit, on the same line. Fitting the wrong optic and compensating by adding watts is the most expensive way to light a floor.

Weight and diameter are also declared, and they increase with power. High-power units need different fixing hardware from what is enough for an industrial high bay luminaire at the lower end of the range, so on lightweight roofs or technical suspended ceilings the fixing must be checked before quantities are confirmed. A properly hung unit does not vibrate, does not swing in the draught from high-speed doors and does not force you to go back up six months later.

Send us the line exactly as the owner, the designer or the end client wrote it, with whatever nickname it carries. We will send it back converted into a product code, with optic, colour temperature and quantity, ready to turn into an order. If you buy for resale, it is closed from your trade account with your pricing already applied and a catalogue personalised with your details.

Aluminium high bay body and heat dissipation: the SMD LEDs, OSRAM LEDs and Philips driver we declare on every UFO LED high bay

A diode does not burn out, it degrades. And it degrades faster the hotter its junction runs. That is why the body is aluminium and why it has fins: the metal draws heat away from the circuit and releases it into the air. A plastic housing made to look like metal saves on manufacturing and makes you pay later, in flux lost after two years and in colour shift. That is why the material is the first thing to ask any supplier about.

Our units are built with materials chosen to withstand the real conditions of an industrial building: die-cast aluminium, IP65 sealing and components with a known thermal curve. An IP65 rating means complete protection against dust and resistance to low-pressure water jets, exactly what you get in a cold store that is hosed down or a workshop with dust-laden air.

Inside, the chip is declared on the datasheet as SMD, type 3030, with OSRAM, Bridgelux or Lumileds chips depending on the production series. Power comes from a Philips Xitanium or Sosen driver. When a unit fails early it is almost never the diode: it is the electronics powering it, running above the temperature they can handle, sealed inside a closed housing and hung at twelve metres, where the air is hotter than at ground level.

There is a wide variety of brands and models of chips and drivers on the market, and not all of them behave the same inside that oven. We publish which one each unit uses. Comparing two LED high bays without that information is comparing two closed boxes, and on a volume purchase you pay for that lack of transparency in full.

LED technology has been mature in this segment for some time, so today the gap between a high-quality unit and a cheap one lies in the thermal assembly and the electronics far more than in the diode. The practical result of a good aluminium-chip-driver combination is a long service life with limited lumen depreciation and stable light quality, with no colour shift or loss of colour rendering. In industrial settings, that translates into fewer trips up on the access platform, which is where the maintenance budget really goes.

An industrial high bay luminaire is also judged by what you cannot see. The Zhaga connector on top lets you attach accessories without opening the body or breaking the seal, and that standardisation is what prevents a later modification from ruining the factory IP65 rating. It is the difference between an LED high bay that can evolve and one that has to be replaced entirely when the use of the floor changes. Ask for the datasheets of the models you are comparing and check those three lines: chip, driver and body. Once that is decided, we will confirm your quantities with no surprises.

IP65 and 90º: why a 150W 4000K industrial LED high bay performs differently from the same LED light at 5000K or 6000K in a ceiling light

Three figures on the datasheet decide the result, and none of them is the wattage: ingress protection rating, beam angle and colour temperature. Those are the three you need to have decided when you place the order.

The sealing determines where the fitting can go. With IP65 it can be used in cold stores, wash-down areas, open loading bays and workshops with a lot of airborne dust. An industrial high bay without adequate sealing collects dust inside the optic and loses output without anyone noticing, because the drop is gradual and the eye adjusts. If your floor is cleaned with a hose, that line is non-negotiable.

The angle decides the distribution. We manufacture 60º, 90º and 120º optics. The widest floods the surface and works at lower heights; the intermediate one is the middle ground for medium-height buildings; the narrowest concentrates light and is the one that solves narrow aisles between tall racks and ceilings above twelve metres. At the same wattage, switching from one optic to another changes the number of light points and the spacing between them, and with that the lux that actually reaches the working plane. So it also changes what you end up buying.

Kelvin does not change how much light there is, it changes how it is perceived. Neutral 4000K is the general working tone, one that does not tire the eyes over a long shift or make the building look like an operating theatre. Moving up to cool 6000K gives a sense of sharpness for inspection and visual checks, at the cost of a harsher atmosphere. A large part of the catalogue comes with switchable CCT, three selectable colour temperatures on the unit itself, which means you do not have to decide the tone at the purchasing desk: it is set during installation, with the selector in plain view.

Then there is glare, which is easily overlooked at height. The narrower the optic, the more concentrated brightness is perceived from below, and that contrast is tiring at fixed workstations where the operator looks up frequently. If there are screens, glass or polished surfaces below, the reflection bothers people before the direct source does, and it is corrected by moving the light point out of the line of sight long before reducing power.

It is best to fix the colour temperature for the whole floor before ordering. Two tones under the same roof can be told apart from the far end of the building and force you to redo the whole row so that they match. On the datasheet of an LED high bay luminaire, that figure sits next to the beam angle and the colour rendering index (CRI), which is the third parameter to check when product colour inspection takes place underneath. Decide the colour temperature for the whole floor before confirming the order, ask for a sample unit if you are unsure and order the rest once you have seen it switched on in place.

What is specified at the factory and cannot be added later: fixings, CCT and the dimmable 1-10V industrial LED high bay, 150W dimmable or 200W dimmable, with low energy consumption

Some decisions only exist while the order is still open. Once eighty units are hanging at nine metres, correcting them costs platform hire, a closed aisle and a second installation invoice. There are three of them, and it is best to have them settled before you confirm.

The first is what it will hang from. Hook, eyebolt or suspension cable are not interchangeable depending on the structure, and on lightweight roofs or technical suspended ceilings the fixing hardware is checked beforehand, not on site. Tell us what you are going to hang it from and the suspension accessory goes on the same order line.

The second is the colour temperature. The switchable CCT version leaves the tone open until installation; the fixed-tone version must be ordered with the tone already decided for the whole floor. Either works, but you cannot swap one for the other afterwards.

The third is dimming, and it is the most expensive to correct. A unit that does not come dimmable from the factory cannot be made dimmable later with an accessory. Our dimmable versions work with the 1-10V protocol, analogue and with no proprietary electronics in between: a standard wall dimmer will do, and so will the building's existing management system. Everything else is built on that input, starting with motion sensors, which fit into the socket on the top cover without opening the body or running new cable back to the distribution board.

The numbers add up on their own on the night shift: a floor that dims to a fraction of its output when nobody is there and only rises to full power when the sensor detects someone uses far less energy than one running at full output for twelve hours straight. Dimmable LED lighting is what separates a designed installation from a simple fitting replacement. Tell us if you want it dimmable and with a sensor and we will prepare your order with the correct version from the first unit; if the project runs in phases, we note it on your account so that replacements come out identical.

Where the LED high bay ends in your schedule: LED ceiling lights, LED linear fittings and 300W outdoor LED floodlights for the rest of your industrial buildings

A complete floor is rarely solved with a single format, and a project's lighting schedule reflects that. Knowing where this range ends and another begins stops you buying the same thing twice or leaving an area half lit.

The boundary is drawn with two short questions. The first is the height at which the fitting sits: above five metres the high bay takes over, and below that, formats that stay out of the direct field of vision work better. The second is whether the light point is indoors or outdoors, because that determines the required ingress protection rating and with it the entire product family. With both answers written down, the schedule is put together in one go rather than piece by piece.

From there, each area has its own line. Over assembly lines, long corridors and the adjoining office, linear luminaires do the work; in changing rooms, toilets and plant rooms, recessed or surface-mounted formats take over; outside, on the loading dock, the yard and the car park, floodlighting comes in, and there the criteria change completely, because the column height is what matters and the beam narrows as that point rises. Each family has its own page and its own calculation: here we simply mark the boundary.

In the schedule, the LED high bay luminaire takes its line and the other families take theirs. Whatever wording the specifier uses for these industrial bay lights, what needs checking on every line is always the same: wattage, optic, colour temperature and ingress protection rating.

What does not change when you move from one family to another is the terms or the person you deal with. We manufacture in-house, so a series stays alive and later replacements slot into the same row with no mismatch in colour. For anyone managing several sites or maintaining a portfolio of installations, that matters more than any line on a datasheet, and it is why it pays to cover every area with a single supplier rather than splitting them among several: energy efficiency is bought once, range continuity pays off with every replacement.

Send us the plan with the areas marked and we will send you back the full schedule, each line with its wattage and optic, priced at your rate. With that in front of you, the order is closed in a single conversation, without requesting quotes item by item.

Frequently asked questions before buying: industrial UFO LED, 100W LED, 150W LED and industrial LED lamps

High bay, luminaire or lamp? Does the product change depending on how you ask for it?

The product does not change; the person writing does. In a specification it appears as an industrial high bay light; in a search engine people type industrial LED high bay lighting, or even highbay as one word; in a maintenance quote they are listed as industrial LED high bay lamps. We work with datasheet terminology, the only kind that lets you compare two units without having them in front of you: wattage, luminaire flux, efficacy in lm/W, beam angle, colour temperature, IP rating and driver type. Send us the text as it is and we will convert it into product codes.

How do I open a trade account and what changes when I buy?

You fill in the registration form, attach the documents proving your business activity, whether as a company or as a sole trader, and send them to comercial@factorled.com. Once approved, your account moves to wholesale pricing with volume discounts, access to a catalogue personalised with your logo and details, blind shipping with no visible sender and a dropshipping option with the range connected to your shop and updated daily. Credit with deferred payment is granted subject to review: each application is assessed individually and is subject to approval; it is never automatic. Payment is accepted by Visa and Mastercard, PayPal, Stripe and bank transfer.

What warranty does it have and what do I need to make a claim?

Cover extends up to six years of warranty depending on the product, with three years as the baseline for the range. It is not a uniform figure across the whole catalogue: each datasheet states its own, because the cover depends on the components used in that specific model. To process a claim you need the order number and the product code, both available in your customer area together with your invoices.

What is the delivery time and who pays for shipping?

The delivery time depends on the destination and you will see an estimate when you confirm the order; goods leave the warehouse without delay. For the Canary Islands, Ceuta and Melilla, DUA customs processing and prior contact before dispatch are also required. Shipping costs are not a fixed amount: the basket calculates them by weight, volume and delivery zone, and shows you the amount before you confirm payment, because a fitting from the top of the range does not travel like a box of accessories. As soon as the parcel leaves the warehouse, you will receive an email with the tracking number.

What if it arrives damaged or I have units left over from the installation?

Inspect the parcel with the carrier present: if it is damaged, note it on the delivery note before signing anything. If the damage only becomes apparent when you open the packaging, let us know as soon as you see it. Returns at your own discretion are accepted within the period set by our policy, on one firm condition: the original box must be intact, with no stickers or tape stuck to it, and contain everything that left the factory, including inner packaging, manuals and any accessories supplied with the product. If this is not met, a deduction is applied to the refund. Return shipping is paid by the customer. Returns are handled through an RMA request in your customer area, with no phone call needed, and the goods are not moved until that request has been approved.

If you already have the floor dimensions and clear height, your LED high bay order can be closed with a call to 91 805 67 67 or via the website chat. And if you are still deciding between two wattages, send us the plan before you buy: it is cheaper to correct a calculation than to correct an installation at twelve metres.
