Questions people ask about the light engine
Which lights does the light engine fit?
The HD Original and HD Pro Floor and Table Lights, and the older High Definition LED lights. Not the HD Essential, which takes its own bulb.
How do I know which light engine I have?
Stand your light on something steady so you can see the underside of the base. The code is printed there. If there is more than one code you want the top one, and only the part before the first space. A code ending in G1 is the Heritage White finish.
How do I change the light engine?
Switch your light off at the wall and give it a few minutes to cool. The light engine then comes out of the head and the new one goes in the same way. If you would rather be talked through it, call us on the number above.
How long does it last?
We rate the light engine at five years.
Is it dimmable?
The dimming is in your light rather than in the bulb. If your light dims now, it will dim with this bulb in it.
What does the G1 on the end of the code mean?
It is the Heritage White finish. A code without it is the black one.
