Questions people ask about this bulb
Which lights does this bulb fit?
Every Alex LED light ordered before 5 November 2018. The code on the underside of the base reads 15188, 15188A or 15188B.
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.
How long does it last?
We rate this bulb at three 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.
Why does the bulb that arrives say A3530?
It is the same bulb with our newer LED inside, so the reference code changed. It fits and works in the same way as the 15188.
