G9 Capsule LED Bulb 4W 520lm - Warm White

This G9 capsule LED bulb is a tiny bi-pin lamp that drops into the two-pin G9 holders found in many ceiling fittings, wall lights and lamps. It draws just 4W yet gives 520 lumens, so it replaces a 42W old capsule while using a fraction of the power. The light is a 3000K warm white with a Ra 80 colour rendering, and the wide 320 degree beam spreads light almost all the way around the lamp rather than firing it in one direction. As light bulbs go in US terms, this is a bi-pin capsule of the type sold for the same compact holders.

Because the output is even and close to all-round, this bulb suits the small multi-lamp fittings it is designed for: pendant clusters, decorative ceiling lights, picture lights and bedside or table lamps where several capsules share the work. The 320 degree spread fills a shade or diffuser evenly rather than leaving a hot spot, and the warm 3000K tone keeps living rooms, bedrooms and hallways relaxed. Rated IP20, it is for dry indoor positions only, so keep it clear of bathrooms, porches and any damp or outdoor location.

The bulb measures Ø16 by 50 mm and weighs only 10 g, matching the slim profile G9 fittings expect. It runs straight from 220 to 240V AC mains through the G9 cap, with no transformer or driver needed, and reaches an efficiency of 130 lm/W. It is rated for 20,000 hours and is non-dimmable, so pair it with a standard on/off circuit. This G9 capsule sits alongside other cap and shape options in the wider range if you need a different fitting or output.

Product Specification Sheet

Range Datasheet

What fitting does this bulb need?

It has a G9 bi-pin cap, the two-pin push-fit base used in many compact ceiling fittings, wall lights and table lamps. The pins simply push into the holder. Check your fitting is marked G9 before ordering, as the cap is not interchangeable with screw or bayonet types.

What old bulb wattage does it replace?

It draws only 4W but gives 520 lumens, which replaces a 42W old G9 capsule. The 4W figure is the actual power the LED uses, so it cuts running costs sharply while keeping a similar brightness.

Is this bulb dimmable?

No, it is non-dimmable, so it should be used on a standard on/off circuit. Fitting it on a dimmer switch can cause flicker or buzzing and may shorten its life. For dimming, choose a lamp specified as dimmable.

Can it be used outdoors or in a bathroom?

No. It is rated IP20 for dry indoor use only, so it should be kept out of bathrooms, porches and any damp or exposed location. Use it in living rooms, bedrooms, hallways and similar indoor spaces.
