G9 LED Capsule Bulb 4.2W 470lm Dimmable - Warm White 2700K

This is a G9 capsule LED rated at 4.2W, giving 470 lumens of warm white light at 2700K. The capsule form is the small two pin type used in compact fittings, and the LED chips sit inside a clear body so light spreads right around the lamp rather than firing in one direction. It is dimmable, and the retail pack states a 15 year lifespan and a 40W replacement figure. The energy rating is E.

G9 lamps turn up wherever a fitting is too small for a conventional bulb: multi arm wall lights, cluster pendants, cabinet and display lights, cooker hoods and picture lights. If you are replacing halogen capsules, this is the swap most people are making, and the practical difference is heat as much as electricity. A halogen capsule runs hot enough to mark a small shade over time; a 4.2W LED does not. Where several G9 lamps share one fitting, change them all together so brightness and warmth match across the arms.

Dimming needs a dimmer rated for LED loads, usually a trailing edge type, and it needs enough lamps on the circuit to meet that dimmer's minimum load: one 4.2W lamp on an old halogen dimmer is the usual cause of flicker or a short dimming range. At 2700K the light is the warm, slightly yellow tone people associate with halogen and filament lamps, so it sits comfortably beside existing warm white fittings in a living room or bedroom. Each box holds one lamp, and the minimum order is 12, sold in multiples of 12. It sits alongside our wider range of LED bulbs in GU10 and B15 (SBC) fittings, including dimmable candle bulbs in warm white 2700K and cool white 4000K.

How do I know my fitting takes a G9 lamp?

Pull the old lamp out and look at the base. A G9 has two flattened wire loops set close together that push straight into the socket, with no pins to twist and no screw thread.

Will it work on my existing dimmer switch?

It dims on a dimmer rated for LED loads, normally a trailing edge model. An older halogen dimmer often has a minimum load far above 4.2W, which shows up as flicker or a very short dimming range.

Is 470 lumens as bright as the halogen capsule I am replacing?

The pack gives a 40W replacement figure, so it is aimed at the common 40W halogen capsule. In a multi arm wall light the total across all the arms is what you actually notice.

What does 2700K warm white actually look like?

It is the warm, faintly golden tone of old halogen and filament lighting, rather than the cleaner white of 4000K. It flatters wood, warm paint colours and skin tones in the evening.

Does the manufacturer state an IP rating for this lamp?

No IP rating is stated on the specification or printed on the retail pack, so we quote none. Treat it as a lamp for ordinary dry indoor fittings and check the rating of the fitting itself.

How many lamps do I receive?

One lamp per box. The minimum order on this listing is 12 boxes, sold in multiples of 12, so a single order gives you 12 lamps in total.
