Energizer LED Capsule G4 1.2W Clear Non-Dimmable - Daylight 6500K

This is a G4 LED capsule, the small two pin lamp that replaces the halogen capsules used in low voltage fittings. It draws 1.2W and gives 90 lumens at 6500K, a daylight white that reads crisp and slightly blue against the yellow of an old halogen. The capsule body is clear sided with the LED chips set around it, so light leaves across a 300 degree spread rather than being thrown forward in a cone. Two straight pins push into the socket; there is no twist or click to it.

G4 capsules turn up wherever a fitting needs a light source it can hide: under kitchen wall units, inside glass display cabinets, in cooker hood lamps, in reading and desk lamps, and in the small arms of a multi arm pendant. The 6500K daylight output suits work surfaces, display shelves and anywhere you want colours to read true rather than warm. Sitting in a run beside older warm white capsules the difference shows at once, so it is worth changing a whole row together. The manufacturer does not state a supply voltage, so if you are replacing a capsule in a transformer fed or driven fitting, check the old lamp before you order.

It is not dimmable, as the specification and the pack both make clear, so keep it off circuits fed by a dimmer switch or a dimming driver. The pack prints a 15 year lifespan and gives 9W as the replacement wattage for its 1.2W draw. The energy rating is G, with the label quoting 2 kWh per 1000 hours of use. Each unit is a single bulb in its own box, with a minimum order of 12 and further orders in multiples of 12, which suits keeping spares for a fitting that carries several capsules at once. Energizer LED bulbs in B15 and GU10 fittings are on sale here too.

Will it fit my existing G4 fitting?

The cap is G4, the two straight pins that push into the socket, so it suits any fitting made for a G4 capsule. Check the pin spacing on the old lamp and the supply feeding the fitting before you order.

How bright is 90 lumens in practice?

It is a modest output, and the pack quotes 9W as the halogen wattage it replaces. Think of it as lighting a shelf, a cabinet or a work surface rather than a whole room.

What does 6500K daylight actually look like?

It is the coolest, whitest setting on the usual scale, closer to midday sky than to the yellow of a halogen capsule. Colours read true under it, which is why it suits task areas and display shelves.

Can I put it on a dimmer?

No. Both the specification and the pack give this lamp as non dimmable, so a dimmer switch or a dimming driver can cause flicker, buzzing or an early failure.

Is an IP rating given for this lamp?

The manufacturer does not state one, so treat it as an indoor lamp for dry, protected positions inside a fitting rather than anywhere it might meet moisture.

How many do I have to buy?

Each unit is one bulb in its own retail box. The minimum order is 12 units, and any further quantity goes up in multiples of 12, which makes it easy to keep spares.
