Frequently Asked Questions
Will this fit my existing GU10 downlight fitting?
Yes — this uses a standard GU10 twist-and-lock cap and fits all standard GU10 downlight fittings. Simply twist out the old bulb and twist in the new one. No transformer required — runs directly on 240V mains.
Is this bulb dimmable?
Yes — fully dimmable. However, you must use an LED-compatible dimmer switch. Standard halogen or incandescent dimmers may cause flickering or buzzing. For best results, use LED-specific dimmers from brands such as Varilight or Lutron. If you’re unsure, contact us on 01603 381095.
What does 4000K mean?
4000K is a cool white colour temperature — bright, crisp, and neutral. It’s more energising than warm white (2700K) but less clinical than daylight (6000K). Ideal for kitchens, bathrooms, offices, and task lighting areas.
What is the difference between a flood and a spot beam?
A 36° flood beam spreads light more widely and evenly across a room, reducing harsh shadows. A narrow spot (e.g. 24°) concentrates light in a tighter cone, better suited for accent or feature lighting. This bulb’s flood beam makes it ideal for general ambient and task lighting.
Can this be used in a bathroom?
Yes — when installed in an appropriate IP-rated GU10 fitting suitable for the bathroom zone. The bulb itself must be housed in a fitting with the correct IP rating for its location (e.g. IP65 for zones 1 and 2).
