Description
This is a 40W fire glow lamp on a B22 bayonet cap, with the familiar rounded GLS shape and a deep red glass envelope. It gives 390 lumens at a colour temperature of 1,950 Kelvin, a good deal warmer and redder than the 2,700K most household bulbs run at, so the light reads as glowing embers rather than as general room lighting. The filament is on show through the tinted glass, and at 40W it behaves the way filament lamps do, at full brightness the instant you switch it on.
Fire effect heaters, imitation coal and log fires and other decorative fittings that take a standard bayonet lamp are the usual home for a bulb like this, and it will sit in any ordinary B22 holder where you want a red glow rather than white light. Bar backs and window displays are the other places it earns its keep. Before you order, check the cap on the old lamp: B22 has two small pins on the sides of a smooth metal cap and locks in with a push and a quarter turn, while a screw cap threads in instead. It is worth checking the maximum wattage marked on the fitting as well, since a 40W filament lamp runs hot in use.
The pack states a lamp life of 1 year or 1,000 hours and more than 4,000 switching cycles, and gives the beam angle as 270 degrees, so the glow spreads all round rather than in one direction. It is listed as non-dimmable, so plan on a plain switched circuit rather than a dimmer. Its energy rating is G at 40kWh per 1,000 hours. Each unit is one boxed bulb, with a minimum order of 10 and multiples of 10 after that. A 60W fire glow version on the same B22 cap, at 710 lumens, sits alongside it.

Frequently Asked
Will this fit an electric fire that takes a bayonet bulb?
If the holder is a B22 bayonet, yes. B22 has two pins on a smooth metal cap and locks in with a push and a quarter turn, so check the old lamp before ordering.
What does the light actually look like?
Deep red rather than white. At 1,950 Kelvin and 390 lumens it gives an ember-like glow meant for effect, and it will not light a room on its own.
Can I put it on a dimmer?
It is listed as non-dimmable, so we would run it on a plain switched circuit. If you need a dimmed red glow, choose a lamp that states dimming support.
How long should it last?
The pack prints a lamp life of 1 year or 1,000 hours, along with more than 4,000 switching cycles, so it copes with being switched on and off often.
Is an equivalent wattage or an IP rating given?
Neither is stated for this lamp, so we quote no equivalence figure and no ingress rating. Treat it as an indoor lamp for an ordinary open or enclosed fitting.
How many do I have to buy?
Each unit is a single boxed bulb. The minimum order is 10 units, in multiples of 10 after that, and a 60W fire glow version on the same cap is also stocked.
