Hi I have 8 led light fittings in the same room they are all the same 7402/led1500nw et + hfs
The problem is the first in the loop works fine but all the rest don't and have hardly registered on the multi meter, until last night they were all working

Are these lights 120 Vac lights?

How are they hooked up, series / parallel? Typically, if they are series connected if one light goes out they all will.

What changed between last night and today? Are they indoor or outdoor lights?

Hello - Is everything working again in time for the holiday?
