G250 LED Bulbs

G250 LED bulbs: the giant 250 mm globe for big spaces

The G250 E27 LED bulb is the largest format in the catalogue: a globe 250 millimetres across, almost always built as an LED filament, which stops being a replacement bulb and becomes a decorative lighting piece on an architectural scale. You do not buy it to replace a blown bulb, you buy it to resolve the design of a high ceiling, a double height void or a shop window that needs a focal point. If you are looking for a large filament LED bulb able to carry the character of a room on its own, this is the size.

What a G250 bulb is and what size it has

The G stands for the globe shape and the 250 for the bulb diameter in millimetres: 25 centimetres of glass sphere with a large thread E27 base, in other words twice the diameter of a G125 globe. Inside, the LED filament traces its luminous path in full view, with the look of the classic lamp and the durability of LED: between 15,000 and 25,000 hours compared with the 1,000 or 2,000 of an incandescent. It is worth knowing that a filament piece delivers fewer lumens than an opal LED of the same wattage, between 300 and 800 against 800 or 1100, because its job is to create atmosphere rather than flood a work surface with light.

Where a 250 mm globe is installed

The G250 calls for projects with height and square metres. It is mainly used in:

• Hospitality: restaurants, cocktail bars and high ceilinged dining rooms.
• Hotel receptions and offices, hung alone above the counter.
• Retail shop windows and showrooms, as a draw from the street.
• Stairwells and double height rooms, where a small piece would be lost.

Measure before you install it. It needs genuine clear space around it to read as a sphere, and it demands a lampholder and ceiling fixing sized for its weight and volume: 25 centimetres of glass does not hang from just any lightweight holder. As for visual proportion, a single centred unit commands the room and organises everything around it, while several at different heights create a luminous cluster that fills the vertical void of a stairwell.

How to choose your G250 LED bulb

Start with function: if the globe is going to be the only light in the area, pair it with complementary technical lighting, because a filament brings atmosphere rather than light levels. Move on to colour temperature: 2200K vintage amber reinforces the classic feel and is the natural choice in hospitality, 2700K or 3000K warm white is welcoming and versatile, 4000K neutral white suits corporate spaces and 6000K cool white is out of place on a decorative piece. Then decide whether you want it dimmable: on a sphere this exposed, being able to lower the intensity helps control the glow and change the mood by the hour, but only references that declare it on their spec sheet can be dimmed. Finally, the glass finish is decisive at this size: clear shows the filament with maximum sharpness, while amber and smoked cut the glare and are kinder when the bulb sits at eye level.

Frequently asked questions about G250 LED bulbs

How big is a G250 bulb?

Its bulb is a globe 250 millimetres in diameter, around 25 centimetres, with an E27 base. It is the largest format in the decorative range.

Does it give enough light for a room?

It is a decorative LED filament bulb: it provides between 300 and 800 lumens depending on the model. Combine it with technical lighting if you need working light levels.

What lampholder does it need?

An E27 base and a ceiling fixing able to take its weight and volume. Check the mounting before you hang it.

How many units should I put in a stairwell?

A single centred one if you want a standout piece, or three at different heights to fill the vertical void.
