G4 LED Capsule Bulb 1.2W 90lm Non-Dimmable - Warm White 2700K

This is a G4 capsule LED, the small push-fit bulb with two thin pins rather than a screw or bayonet cap. It draws 1.2W and puts out 90 lumens at 2,700K, and the retail pack gives it as a 9W replacement with a 15 year lifespan. The beam angle is 300 degrees, so light leaves the bulb in almost every direction rather than being thrown forward in a cone. That matters more on a capsule than on most lamps, because a capsule usually sits inside a glass shade, a crystal fitting or a lens that spreads the light again.

Capsules of this size turn up in the places where a full-size bulb will not fit: under-cabinet strips and plinth lights in a kitchen, cooker hood lamps, display cabinets and shelf lights, and the small arms of chandeliers, wall lights and multi-lamp pendants. At 90 lumens a single one is accent light rather than room light, so think of it as one of several working together, or as the light inside a cabinet rather than the light above a table. The 2,700K tone is the warm, slightly yellow white people associate with old filament bulbs, and it sits comfortably beside warm metals and wood.

This one does not dim: the specification says no and the pack is marked non-dimmable, so put it on a plain switch and keep it off a dimmer circuit. It carries a G energy rating, though at 1.2W the running cost is small either way. Check the pin socket in your fitting and what your existing capsule runs at before ordering, as the manufacturer does not state a supply voltage here. Each unit is a single bulb and the minimum order is 12, sold in multiples of 12. It sits alongside our wider range of LED bulbs, which also covers GU10 spots and B15 (SBC) candle bulbs in warm and cool white.

Will this fit any G4 socket?

It fits a two-pin G4 holder, where the pins push straight in without twisting. Check your existing capsule has two straight pins rather than the looped single pin of a G9 lamp.

What voltage does it need?

The manufacturer does not state a supply voltage for this bulb. Check what your existing capsule is rated at, and what the driver or transformer feeding the fitting supplies, before you order.

How bright is 90 lumens in practice?

It is accent-level light, and the pack gives it as a 9W replacement. One will light a cabinet or a cooker hood; a chandelier or cluster will usually want several working together.

Can I put it on a dimmer?

No. Both the specification and the pack mark it non-dimmable, so wire it to a plain switch. On a dimmer circuit a non-dimming lamp can flicker, buzz or refuse to light.

Does the manufacturer state an IP rating?

No IP rating is given for this bulb, so treat it as one for dry indoor fittings only. If you need a rated lamp, choose one where the manufacturer prints the figure.

How long should it last?

The pack prints a 15 year lifespan. It does not print the daily running hours that figure assumes, so treat it as the maker's stated life rather than a guaranteed period.
