B22 GLS 10W LED Bulb Opal - Daylight

This A60 GLS LED bulb fits the familiar rounded household shape and runs on a B22 bayonet cap, known in Britain as a BC fitting and the push-and-twist counterpart to the screw-in styles many US lamps use. It draws just 10 W while producing 1520 lumens, standing in for an old 99 W incandescent bulb of the same form, so the actual power on your bill stays low. The light is 6500K daylight, a crisp, cool-white tone, and the wide 320 degree beam angle spreads it broadly around the room rather than throwing it in one direction.

At 1520 lumens of cool daylight, this bulb suits kitchens, home offices, utility rooms, garages and workshops where a bright, clear light helps with close work and reading. The near-omnidirectional 320 degree spread makes it a good fit for open shades, pendants and ceiling fittings that light a whole room. It is an indoor bulb rated IP20, so keep it to dry interior fittings and away from bathrooms, porches and any outdoor or damp location. One bulb covers a small to medium room comfortably; for larger or task-heavy spaces, pair it with several fittings.

The bulb measures 60 mm across and 105 mm long, weighs 34 g and runs on 220 to 240 V AC mains direct from the bayonet cap, with no transformer needed. It carries a CRI of Ra 80 for natural enough colour, a rated life of 10,000 hours and an efficiency of 152 lm per watt. It is non-dimmable, so use it on a standard on/off circuit rather than a dimmer. The opal A60 envelope diffuses the light evenly for a clean, glare-softened finish.

Product Specification Sheet

Range Datasheet

What fitting does this bulb need?

It has a B22 bayonet cap, known as BC in the UK. You push it into the socket and give it a quarter turn to lock, so it suits any standard bayonet fitting. It is not a screw-in cap, so check your fitting is bayonet before ordering.

What old bulb wattage does it replace?

It draws just 10 W but gives out 1520 lumens, which matches the brightness of an old 99 W incandescent bulb. The LED itself only uses 10 W, so you keep the same light output while cutting the energy used.

What does daylight 6500K look like?

6500K is a crisp, cool white often called daylight. It reads clean and bright rather than warm or yellow, which makes it well suited to kitchens, offices and workshops where clear visibility matters. It is cooler than the warm white usually chosen for bedrooms and living rooms.

Is this bulb dimmable?

No, this is a non-dimmable bulb, so it should be used on a standard on/off switch rather than a dimmer circuit. Fitting it to a dimmer can cause flicker or buzzing and may shorten its life. It is rated for 10,000 hours of use.
