B22 (BC) GLS Bulb 60W 710lm Non-Dimmable - Fire Glow Red 1,950K

Fire glow bulbs do one job and do it well: they sit behind the fuel bed of an electric fire or a stove effect and throw a deep red light that reads as burning coal. This one is a standard GLS shape in red glass with a B22 bayonet cap, drawing 60W and giving 710 lumens at 1,950 Kelvin. That Kelvin figure is the point of it. Household warm white sits around 2,700K; at 1,950K the light drops well down into the amber and red end, which is what makes a plastic or ceramic fuel bed look genuinely lit rather than lamp-lit.

The usual home for one of these is an electric fire, a stove effect unit or a coal effect gas fire that uses a mains bulb behind the fret. It also earns a place in theatre and display work where a warm red wash is wanted from a familiar bayonet fitting, and in a shed or workshop socket where the light is there to be seen rather than to work by. Check the old bulb before ordering: a B22 cap has two small pins on its sides and pushes in with a quarter turn, while a screw cap will not fit.

Its specification lists it as non-dimmable, so give it a plain switch rather than a dimmer circuit. The pack prints a lamp life of 1 year, or 1,000 hours, and the energy label for this bulb shows class G at 60kWh per 1,000 hours. Each unit is a single boxed bulb, and the minimum order is 10, sold in multiples of 10, which suits keeping spares on a shelf. We also stock the same fire glow bulb on a B22 cap in a 40W, 390 lumen version.

Will this fit my electric fire?

It fits any B22 bayonet holder, the cap with two pins on the side that pushes in and turns a quarter turn. Screw cap holders such as E27 will not take it.

What does the light actually look like?

Deep red and low, not a general room light. At 1,950K it is far warmer than a 2,700K household bulb, which is what gives a fuel bed its glowing coal look.

Can I put it on a dimmer?

The specification lists the bulb as non-dimmable, so run it from a plain on and off switch or the fire's own control rather than a dimmer circuit.

How long should it last?

The pack prints a lamp life of 1 year, or 1,000 hours. Buying a couple of spares is sensible, since a fire effect usually runs for long stretches at a time.

Is an LED equivalent wattage given?

No equivalent figure is printed for this bulb. It is a filament lamp drawing a full 60W, and the energy label for it shows class G at 60kWh per 1,000 hours.

How many do I have to buy?

Each unit is one boxed bulb, and the minimum order on this listing is 10 units, sold in multiples of 10, so you receive ten individually boxed bulbs.
