Frequently asked questions
Is this Energizer 4W GU10 bulb dimmable?
No, this is a non-dimmable bulb, so it should be used on a standard on/off switch rather than a dimmer circuit.
How does 3000K warm white compare to daylight bulbs?
3000K gives a soft, yellow-tinted white similar to traditional halogen or incandescent lighting, which most people find warmer and more relaxing than a 6500K daylight bulb.
What halogen wattage does this bulb replace?
At 345 lumens and 4W, it's designed as a direct replacement for a 50W halogen GU10 spotlight.
Is the glass construction safe for everyday use?
Yes, the full glass lens is designed for normal household handling and gives the bulb a traditional, premium appearance compared with plastic-bodied alternatives.
