Eveready 4.5W R39 LED Reflector Bulb E14 - Warm White 3000K Non-Dimmable

The Eveready R39 is a 4.5W LED reflector bulb with an E14 small Edison screw base, delivering 320 lumens of warm white light at 3000K. The R39 reflector shape measures 39mm diameter by 65mm height and concentrates light through a 110° beam angle, making it suitable for directional lighting in wall sconces, desk lamps and decorative fittings that take small screw bulbs.

Designed as a direct replacement for 30W halogen R39 bulbs, the Eveready R39 LED reduces energy consumption by 85% while providing the same warm white output. The bulb is rated for a 10-year service life based on typical domestic use patterns (approximately 10,000 hours at three hours per day), reducing the frequency of bulb changes in hard-to-reach fittings. The non-dimmable construction means the bulb should only be used on standard on/off switches, not with dimmer controls.

The CRI (colour rendering index) rating above 80 means the bulb reproduces colours accurately enough for residential applications including bedrooms, living rooms and hallway lighting. The warm white 3000K output provides a softer light than daylight-temperature bulbs, creating a relaxed tone in the evening without the blue-white cast of higher colour temperatures. The 39mm reflector diameter suits compact fittings where a standard 50mm bulb would be too large.

Can this bulb be used with a dimmer switch?

No. The Eveready R39 is non-dimmable and must only be used on standard on/off switches. Fitting it to a dimmer circuit can cause flickering, buzzing or premature failure even if the dimmer is set to full brightness.

What is the E14 base and where is it commonly used?

E14 is a small Edison screw base, 14mm in diameter, also called SES (small Edison screw). It's commonly used in decorative wall lights, bedside lamps, chandeliers with candle-style fittings, and compact desk lamps where the standard E27 base would be too large.

How does 320 lumens compare to older bulbs?

320 lumens is equivalent to a traditional 30W halogen R39 reflector bulb. This output suits accent lighting, decorative fittings and task lighting at close range rather than primary room illumination.

What does the 110° beam angle mean in practice?

A 110° beam angle provides moderately wide coverage. In a wall sconce mounted 2m high, the light spreads approximately 1.8m wide at floor level, making it suitable for hallway lighting or washing light across a wall feature rather than creating a tight spotlight effect.
