Description
This is a 250W infra red heat lamp with an E27 (ES) screw cap, in diffused hard glass. The wide reflector bowl throws its output forward rather than all round, and the diffused finish softens the glare a clear lamp would give. The pack gives 1300 lumens at 2350 Kelvin, a warm white low enough on the scale to read distinctly amber, and prints a five year lamp life. A lamp of this type is bought for the warmth it radiates as much as for the light it puts out.
E27 is the larger of the two common screw caps used in the UK, roughly 27mm across the thread, so the lamp drops into any standard ES holder. Two things are worth checking before you order. The first is that the holder and its wiring are rated to take 250W, because a great many decorative fittings stop well below that. The second is clearance: the head is far wider than a household bulb, so leave air around it rather than pushing it into a narrow shade. Because the reflector sends its output one way, mounting the holder so the lamp faces down or across the area you want warmed gets the most from it.
The specification lists the lamp as non-dimmable, so run it from a plain on/off switch or a timer rather than a dimmer circuit. It carries energy class G at 250kWh per 1000 hours, which is the honest cost of a lamp whose job is heat as much as light. No IP rating is printed by the manufacturer, so keep it to dry indoor positions. It arrives as a single boxed lamp with a minimum order of one, and it sits alongside our wider range of bulbs, which runs from B15 (SBC) pygmy and candle lamps to E27 GLS filament types.

Frequently Asked
Will this fit an ordinary screw lampholder?
It takes an E27 (ES) holder, the larger of the two UK screw caps at around 27mm across the thread. Check the holder and its wiring are rated for 250W before fitting.
How bright is it, and what does the light look like?
The pack gives 1300 lumens at 2350 Kelvin. That is a warm white sitting below the usual 2700K household warm white, so it reads noticeably amber rather than neutral.
Can I run it on a dimmer switch?
No. The specification lists it as non-dimmable, so use a plain on/off switch, a timer or a thermostat rather than wiring it into a dimmer circuit.
Is an IP rating given for this lamp?
The manufacturer states none, so there is no published protection against moisture or dust. Treat it as a dry indoor lamp and keep it in a suitable enclosed holder.
How long does the manufacturer say it lasts?
The retail pack prints a five year lamp life. As with any lamp, actual life depends on how often it is switched and the conditions it runs in.
Why is the energy class G?
The label gives class G at 250kWh per 1000 hours. An infra red lamp puts much of its input into radiated heat, which the lumens-per-watt scale counts as waste.
