Description
This is a bayonet cap LED bulb in the traditional GLS shape, the rounded household bulb profile that most UK table lamps, pendants and ceiling fittings were built around. It draws 14W and gives 1,521 lumens, and the pack rates that as a replacement for a 100W conventional bulb. The light is 6,500K daylight: a crisp, blue-white light rather than the yellow of an old filament lamp. The bulb has a frosted white envelope rather than a clear one, which diffuses the light source into an even glow instead of bright points. It arrives as a box of two.
Daylight at 6,500K is the coolest of the common colour temperatures, and it suits places where you want to see clearly rather than settle in: kitchens, utility rooms, garages, workshops, home offices, garden sheds and stairwells. It reads sharp against warm white bulbs, so if the rest of a room runs at 2,700K or 3,000K, either change the lot or keep the daylight bulb to one working area. The 200 degree beam spreads light around the lamp rather than forward, which is what makes a GLS bulb suit a shade, a pendant or an upward-facing fitting.
There is no dimming: the specification lists this bulb as non-dimmable, so pair it with an ordinary on/off switch; a dimmer circuit can cause flicker or buzz and shorten the life of a lamp not built for it. The pack prints a 10 year lamp life, and the energy label gives class E. It is rated IP20, which means no protection against water, so keep it to dry indoor positions. Each box holds two bulbs and the minimum order is six boxes, twelve bulbs in all. It sits alongside our wider range of LED candle, golf and GLS bulbs in B15, B22 and E27 caps.

Frequently Asked
Will this fit my existing light fitting?
It takes a B22 bayonet cap, the fitting with two small pins on the metal base that pushes in and twists a quarter turn. Check the old bulb for those pins rather than a screw thread.
Can I use it with a dimmer switch?
No. The specification lists this bulb as non-dimmable, so it needs an ordinary on/off switch. On a dimmer circuit you are likely to get flicker, buzzing or a shortened life.
How does 1,521 lumens compare with the bulb I am replacing?
The pack rates it as a replacement for a 100W conventional bulb, which is the brightest of the old household sizes. For most rooms that is a main ceiling or standard lamp bulb rather than a bedside one.
What does 6,500K daylight actually look like?
It is a cool, blue-white light with no yellow in it, the coolest tone commonly sold. Beside a 2,700K warm white bulb the difference is obvious, so it is worth matching bulbs within one room.
Where can I use a bulb rated IP20?
IP20 means no protection against water at all, so this belongs in dry indoor positions only. It is not suitable for outdoor lanterns, porches or anywhere it could be rained on or splashed.
How many bulbs do I get, and is there a minimum order?
Each box contains two bulbs. The minimum order is six boxes, sold in multiples of six, so the smallest order brings you twelve bulbs in total.
