High Definition Lights use specialist bulbs with our own Daylight Wavelength Technology™, designed to replicate the daylight spectrum. Our older models use patented halogen bulbs.

To find the replacement bulb code for your light, simply look on the underside of the base of your light. There will be a section for replacement bulbs or light engines. Look for a code that matches one of the bulb codes shown below. If you cannot find it, use the live chat function or call 0800 032 9366.
