E27 (ES) LED R63 Bulb 7.3W 806lm Non-Dimmable - Warm White 2700K

This is a 7.3W LED reflector bulb in the R63 shape, with an E27 screw cap and 806 lumens of warm white light at 2700K. R63 means a head 63mm across with a shallow domed face, so the light is pushed forward out of the front of the bulb rather than spreading evenly in all directions. The pack rates it as a replacement for a 60W filament reflector and prints a 15 year lifespan, based on 15,000 hours of use. The energy rating is E.

Reflector bulbs of this size are the usual choice for recessed ceiling spots and adjustable track heads with a screw socket, and for older kitchen and hallway fittings built around 60W R63 lamps. Because the beam is directed, one of these over a worktop, a reading chair or a run of shelving puts light where you want it instead of washing the whole ceiling. At 2700K the tone is the warm yellow people know from a traditional filament lamp, which suits living rooms, dining rooms and bedrooms. If you are matching bulbs already in the same fitting, check they are 2700K as well: a 4000K lamp next to this one will read noticeably colder.

Check the cap on the old bulb before ordering: E27, also written ES, is the larger screw cap at 27mm across the threads, and the smaller E14 will not fit. This one is not dimmable, so give it a plain on and off switch; on a dimmer it may flicker, buzz or fail early. The IP20 rating means dry indoor positions only. Each unit is a single boxed bulb and the minimum order is 12, in multiples of 12, which suits a landlord or a fit-out where the same spot repeats. If other fittings in the house need filling, our LED bulbs also cover GU10, and B15 candle and golf shapes.

Which fittings does an E27 cap screw into?

E27, also marked ES, is the larger of the two common screw caps and measures 27mm across the thread. If the old bulb has a wide screw base rather than push and twist pins, this one will fit.

Can I run it from a dimmer switch?

No. The pack marks it non dimmable, so wire it to an ordinary on and off switch. On a dimmer circuit it may flicker, hum or fail well before its rated hours.

What will 7.3W and 806 lumens replace?

The pack rates it as a 60W replacement, so it gives light broadly equal to an old 60W filament reflector while drawing 7.3W. The 806 lumen figure is measured in a sphere.

What does 2700K warm white look like in a room?

It is the soft yellow tone of traditional filament lighting, warmer than the crisper 4000K cool white, and it flatters wood, warm paint colours and skin tones in the evening.

What does the R63 shape mean for the beam?

R63 is a reflector shape with a face 63mm across, which pushes most of the output forward as a directed beam instead of spreading it evenly around the whole room.

What does the IP20 rating mean?

IP20 means the bulb is protected against solid objects such as fingers but has no protection against water, so it belongs in dry indoor fittings only.
