Energizer Capsule G9 1.8W Clear Non-Dimmable - Daylight 6500K

This is a G9 capsule bulb, the small two-pin lamp that slots into wall lights, cooker hoods, mirrored fittings and the compact heads on multi-arm ceiling lights. It draws 1.8W and gives 200 lumens, and the retail pack states it as a 20W replacement, so it is the LED answer to the little halogen capsules that ran hot enough to discolour a shade. The light is 6500K daylight, the coolest and whitest tone in common domestic use, closer to an overcast midday sky than to a candle flame. The energy rating is E.

Daylight at this temperature does a specific job: it keeps whites reading as white and stops colours shifting the way they do under a warm lamp. That makes it useful over a worktop, inside a cooker hood, in a utility room, at a dressing mirror, or in a garage or workshop fitting. In a living room or bedroom it will read as clinical beside warm white, so choose the tone room by room rather than fitting one throughout. The 300 degree beam spreads light almost all the way round the capsule rather than throwing it forward, which suits fittings where the bulb sits behind glass or inside a diffuser.

This lamp is not dimmable, so run it from a plain on/off switch; on a dimmer circuit expect flicker, buzzing or a refusal to light, and change the switch rather than the bulb. The pack prints a 15 year lifespan and holds one bulb. Fitting is simply a push: line the two pins up with the socket, press in squarely, and keep the power off while you do it. The minimum order is 12 units, in multiples of 12, which suits changing every capsule in a multi-arm fitting at once and keeping a few spares in the drawer.

Will this fit the G9 socket in my existing light?

Yes, if the old lamp had two stiff looped pins side by side that push straight into the holder. G9 is a mains-voltage cap, so there is no driver or transformer to check.

Is 200 lumens enough, and what does 6500K actually look like?

It matches the output the pack gives for a 20W capsule, so it is a like-for-like swap rather than an upgrade in brightness. At 6500K the light is crisp and white with no yellow in it.

Can I put it on a dimmer switch?

No. The specification gives it as non-dimmable, and on a dimmer circuit you are likely to get flicker, buzzing or no light at all. Use a plain on/off switch.

How many bulbs do I receive?

One bulb per box. The listing carries a minimum order of 12 units, bought in multiples of 12, so you would receive twelve individually boxed lamps.

Where can I safely use it?

The manufacturer states no IP rating for this lamp, so treat it as one for ordinary dry indoor fittings and check that any enclosed fitting is rated for the lamp you put in it.
