E27 Reflector 8W LED Bulb R63 - Cool White

This E27 reflector LED bulb gives a directed, forward beam in the R63 shape, sized at 63 mm across and 104 mm tall. It draws 8 W and produces 720 lumens at 4000K cool white, throwing light through a 120 degree spread rather than the all-round glow of a standard household lamp. The cap is the E27 Edison Screw, known as ES in the UK, and the bulb is a like-for-like fit in fittings that took an old R63 reflector. American buyers will recognise this as a screw-base reflector lamp, with the E27 thread matching the common medium screw fitting.

The directional beam suits spotlights, track heads, downlight cans and accent fittings where the light needs to point at a particular wall, shelf or work surface rather than fill the whole room. The 120 degree angle is wide enough for general task and display lighting yet keeps the output focused, so it works well over a kitchen worktop, in display alcoves or in recessed ceiling fittings. The cool white 4000K tone reads as a clean, neutral light that holds colours accurately, helped by the Ra 80 colour rendering. As an IP20 lamp it is for dry indoor positions only and should be kept clear of bathrooms, porches and any outdoor or damp location.

The bulb replaces a 54 W old reflector lamp while pulling only 8 W, so it covers the same job for a fraction of the running cost, and it carries a rated life of 15,000 hours. It runs on 220 to 240 V AC mains through the E27 thread, with no separate driver or transformer needed. This is a non-dimmable lamp, so pair it with a standard on or off switch rather than a dimmer circuit. The finish is white and the unit weighs 58 g. The wider Niori range covers further E27 and reflector LED options in matching tones.

Product Specification Sheet

Range Datasheet

What fitting does this bulb need?

It uses an E27 Edison Screw cap, also called ES, which screws into the standard larger screw-thread holder. It is shaped as an R63 reflector, so it drops straight into fittings that previously took an old R63 reflector lamp of the same diameter.

What old bulb wattage does it replace?

The LED draws just 8 W yet replaces a 54 W old reflector lamp, giving 720 lumens of light. The low 8 W draw is the actual power used, so you get the same brightness for far less energy.

Is this bulb dimmable?

No, it is a non-dimmable bulb and should be run from a standard on or off switch. Fitting it on a dimmer circuit can cause flicker or buzzing, so use a plain switched circuit instead.

What does the 120 degree beam and 4000K tone suit?

The 120 degree directional beam points the light forward, which suits spotlights, track heads and accent fittings over worktops or displays. The 4000K cool white gives a clean, neutral light with Ra 80 colour rendering for accurate-looking colours.
