Questions people ask about this bulb
Which lights does this bulb fit?
Alex Varifocus LED lights ordered before 5 November 2018, and the Gemini Focus Adjustable Light.
How do I know which bulb I have?
Stand your light on something steady so you can see the underside of the base. The bulb code is printed there. If there is more than one code you want the top one, and only the part before the first space. On this site a code ending in A is a single bulb and one ending in B is a twin pack.
How do I change it?
Switch your light off at the wall and give the bulb a few minutes to cool. The old bulb then comes out and the new one goes in the same way it came out. If you would rather be talked through it, call us on the number above.
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.
