High Definition Light Engine - 2021

Light Engine For High Definition Light

This light engine is suitable for all High Definition LED Light models, although if you purchased your High Definition Light between 1st November 2020 & 31st Jan 2021, the light engine fitted originally will be of a slightly different specification. This model has a wider beam.

If you are unsure which you require, please check the underside of the base of your light for the replacement bulb code.

If the code on the base of your light is T274, then your light is fitted with a light engine that has a narrower beam. If you wish to purchase that model, please click here. Alternatively, this wider beam version will work in your existing light.

If you purchased your High Definition Light before November 2020 then you most likely have a halogen version instead, and require a replacement bulb - click here.

T277 = Black High Definition Light Engine
T277-G1 = Heritage White High Definition Light Engine
