G9 Capsule LED Bulb 5W 6000K - Clear

This is a small capsule lamp with a G9 base and a clear glass envelope, so the light leaves it bright and undiffused. At 5W it gives around 420 lumens, a crisp daylight white that reads cool and clean rather than cosy. The electronics are non-flickering, which keeps the light steady where a fitting holds a cluster of capsules close together. It is not dimmable, so run it from an ordinary on-off switch.

G9 capsules turn up in all sorts of places: multi-arm ceiling fittings, small pendants, wall lights, display and picture lighting, and the little glass shades on kitchen and hallway fittings. We reach for a 6000K lamp like this one where the job is seeing clearly rather than settling in for the evening, so kitchens, utility rooms, home workshops, garages and desks. If you want a softer glow in a sitting room, choose a warmer capsule instead. Where a fitting takes a set, we would change them all at once so the colour stays matched across the arms.

The glass is clear and the body compact, which keeps it discreet inside an open shade where the lamp itself is on show, and it weighs next to nothing in the hand. Care takes moments: switch the power off, give the glass time to cool, then hold it by the base rather than the envelope and wipe it with a dry cloth, since dust settling on clear glass dulls the output faster than you would expect. Fingerprints show up more on a clear capsule than on a frosted one, so that quick polish is worth doing whenever you clean the fitting around it. It carries a three year warranty.

How much light does it give?

Around 420 lumens from 5W, with a wide 320 degree spread, so it lights an open shade evenly rather than throwing a narrow beam.

Will it fit my existing G9 fitting?

It has a standard G9 two-pin base and measures 16mm across by 50mm tall, so it suits most G9 holders and slim glass shades.

Can I use it on a dimmer?

No. This one is non-dimmable and should be wired to a plain switch; running it on a dimmer circuit can cause flicker or shorten its life.

What does 6000K look like in a room?

It is a daylight white, noticeably cooler and bluer than a warm white lamp. It suits task areas and workspaces; for relaxing rooms most people prefer 2700K or 3000K.

How long should it last?

It is rated at 25,000 hours of average life and carries a three year warranty.

Is it safe to touch when changing it?

Turn the supply off and let the capsule cool first, then handle it by the base. Avoid gripping the clear glass, as skin oils leave marks that show once it is lit.
