Description
The Eveready R50 is a 4.9W LED reflector bulb with an E14 small Edison screw base, delivering 450 lumens of warm white 3000K light. The R50 reflector shape directs light forward in a 110-degree beam, making it suitable for recessed downlights, track lighting, reading lamps and accent fixtures where directional light is needed rather than omni-directional spread.
Designed as a direct replacement for 40W halogen R50 bulbs, the Eveready consumes 88% less energy while producing comparable light output. The E14 base fits standard small Edison screw fittings common in UK and European residential lighting, particularly in older downlight housings, bedside lamps and wall-mounted reading lights where the smaller base diameter is required.
The bulb measures 50mm diameter by 85mm height, giving it the same footprint as a traditional R50 reflector. The 3000K colour temperature produces a warm white tone that sits between yellow candlelight and neutral daylight, suited to living rooms, bedrooms and hospitality spaces where warmer tones are preferred. The bulb is rated for over 10,000 switching cycles and a 10-year lifespan under typical domestic use, with a colour rendering index above 80 for reasonably accurate colour reproduction.
The bulb carries an F energy rating under the current EU energy labelling system, which reflects the efficiency of small-wattage LED bulbs relative to the updated rating scale introduced in 2021. It is non-dimmable and should only be installed in non-dimming circuits to avoid flicker or premature failure.

Frequently Asked
What does the R50 shape mean?
R50 refers to a reflector bulb with a 50mm diameter. The reflector shape directs light forward in a focused beam rather than spreading it in all directions, making it suitable for downlights, track lighting and spotlights.
Can this bulb be used in a dimmer circuit?
No. This bulb is non-dimmable and must only be installed in non-dimming circuits. Using it with a dimmer switch will cause flicker, buzzing or early failure.
What halogen bulb does this replace?
This 4.9W LED replaces a 40W halogen R50 bulb while producing the same 450 lumens of light output. The E14 base matches standard small Edison screw fittings used in most halogen downlight and reading lamp fixtures.
What is the beam angle?
The bulb produces a 110-degree beam, which is wide enough to light a typical ceiling downlight spread without creating a harsh spotlight effect. This makes it suitable for general room lighting as well as task lighting.
