Description
The Energizer R63 is a 7.3W LED reflector bulb with an E27 screw base, producing 806 lumens at 2700K warm white. The R63 designation refers to the 63mm diameter reflector shape, which directs light forward in a controlled beam rather than scattering it in all directions like a standard GLS bulb. This makes it suited to recessed downlights, track lighting and spotlights where focused illumination is needed.
Non-dimmable by design, the bulb provides consistent 806-lumen output from switch-on, with no warm-up period. At 7.3W it replaces 60W incandescent reflector bulbs at roughly one-eighth of the power consumption, while the 2700K colour temperature matches the warm glow of traditional tungsten filament bulbs. The bulb fits standard UK E27 lamp holders found in most domestic and commercial recessed ceiling fittings.
The reflector housing is coated internally with a silver finish that bounces light forward through the frosted front lens, concentrating the beam into a narrower spread than omnidirectional bulbs. This beam control makes the R63 useful for task lighting over kitchen worktops, reading areas, and display shelving where directional light prevents spill into surrounding areas. The bulb measures 106mm in height and 63mm in diameter, weighing 50g.
Energizer rates this bulb with a 15-year lifespan based on average domestic use of 2.7 hours per day. The Energy Rating of E reflects current EU energy label standards for LED bulbs, where the scale has been recalibrated and most LEDs now fall into D-G ratings rather than the previous A+ grades.

Frequently Asked
Can this bulb be used in a dimmer circuit?
No. This is a non-dimmable LED bulb. Installing it on a dimmer switch may cause flickering, reduced lifespan or failure. If you need dimmable R63 reflector bulbs, search Niori for dimmable variants.
What wattage incandescent bulb does this replace?
At 806 lumens output, this 7.3W LED replaces a 60W incandescent reflector bulb. The warm white 2700K colour temperature matches the tone of traditional tungsten filament bulbs.
What is the beam angle?
R63 reflector bulbs typically produce a beam angle between 100-120 degrees, narrower than the 200+ degree spread of standard GLS bulbs. The internal reflector coating directs light forward rather than sideways, making these bulbs suited to downlights and spotlights.
How long does this bulb last?
Energizer quotes a 15-year lifespan based on average domestic use of 2.7 hours per day. Actual lifespan depends on usage patterns, heat dissipation in the fitting, and voltage stability on the circuit.
