Description

The Energizer R50 is a 4.2W LED reflector bulb with an E14 small Edison screw base, delivering 470 lumens of warm white 2700K light. The R50 reflector shape concentrates the beam into a 120-degree spread, making it suited to directional fittings such as spotlights, downlights, and table lamps with shades that benefit from focused rather than diffused light.

Designed as a direct replacement for 40W incandescent R50 reflector bulbs, the 4.2W LED draws approximately 90% less power while producing equivalent light output. The non-dimmable operation ensures consistent brightness without flicker, which suits bedside lamps, kitchen under-cabinet lighting, and display lighting where stable output is required. The E14 base fits smaller decorative fittings and European-style spotlight tracks.

The 50mm diameter and 85mm height allow the bulb to fit most compact R50 fittings without protruding beyond the shade or housing. Energizer rates the LED for a 15-year lifespan based on average domestic use of 3 hours per day, reducing replacement frequency compared to halogen or incandescent equivalents. The warm white 2700K temperature produces a soft yellow-toned light comparable to traditional tungsten filament bulbs.

Frequently Asked

What wattage incandescent does this replace?

The 4.2W LED produces 470 lumens, equivalent to a 40W incandescent R50 reflector bulb. The energy consumption drops by approximately 90% while maintaining the same light output.

Is this bulb dimmable?

No. This LED is non-dimmable and should not be used with dimmer switches, as doing so may cause flickering or damage to the bulb.

What's the beam angle?

R50 reflector bulbs typically produce a 120-degree beam spread. The reflector coating inside the bulb concentrates light forward rather than radiating it in all directions like a standard GLS bulb.

How long does it last?

Energizer rates this LED for a 15-year lifespan based on 3 hours of use per day, or approximately 16,425 hours of continuous operation before light output degrades below usable levels.
