G4 LED Capsule Bulb 1.8W 215lm Non-Dimmable - Warm White 2700K

This is a G4 capsule bulb, the small two pin lamp that sits in the compact fittings where a halogen capsule once did the same job. It draws 1.8W and gives 215 lumens, which the pack puts at the equivalent of a 20W halogen capsule. The colour is warm white at 2700K, the yellow toned warmth most people associate with the halogen it replaces. The beam angle is 300 degrees, so light leaves the lamp in nearly every direction instead of being pushed forward in a cone. The pack prints a 15 year lifespan, and the energy rating is E.

G4 capsules turn up in the fittings nobody thinks about until one stops working: under cupboard strips in a kitchen, cooker hood lamps, glass display cabinets, plinth lighting, desk and bedside lamps, and the small arms of multi arm pendants. The two pins sit very close together, and a G4 will not go into a G9 socket even though the two caps look alike at arm's length, so pull the old lamp out and count before you order. The wide spread earns its place where the bulb is seen through clear glass or has to light a shelf above and below it at once.

It is not dimmable, and the pack says so on the front, so wire it to an ordinary switch rather than a dimmer, where a non dimming lamp can flicker, hum or fail early. The manufacturer states no IP rating, so treat it as a lamp for dry indoor positions. Each box holds one bulb and the minimum order is 12, sold in multiples of 12, which works out well when you are relighting a whole run of cabinet lamps or a pendant with several arms and want a spare in the drawer. It sits alongside our wider range of LED bulbs, which takes in GU10 spots and B15 candle lamps.

Will this fit a G9 lamp holder?

No. G4 and G9 both have two pins and look alike from a distance, but the pin spacing and the holders are different. Check the cap marking on the lamp you are taking out before you order.

What voltage does it run on?

The manufacturer does not state an operating voltage in the specification or on the pack, so check what your existing capsule and any transformer or driver in the fitting are rated at before ordering.

Can I put it on a dimmer switch?

No. The pack marks this lamp non dimmable, so it belongs on a plain switched circuit. Run on a dimmer, a non dimming lamp can flicker, buzz or fail well before its rated life.

How bright is 215 lumens in practice?

It matches a 20W halogen capsule by the figure on the pack, which is enough for a single cabinet shelf, a cooker hood or one arm of a multi arm pendant rather than lighting a whole room.

Is it rated for damp or outdoor positions?

The manufacturer states no IP rating for this lamp, so we make no claim for it. Treat it as a dry indoor lamp and keep it away from damp or outdoor positions.

How many bulbs will I receive?

Each box contains one bulb. The minimum order on this listing is 12 boxes, sold in multiples of 12, so a single order gives you twelve individually boxed lamps.
