Hi everyone. I have replaced a normal bulkhead light with an LED maintained emergency bulkhead light which I required to be permanently on, I therefore linked out L1 and L2. Initially it worked fine for a week or so and then during a routine test it failed to light when the supply was removed, the green charge LED also failed to illuminate when the power was restored. I assumed it was a faulty unit and obtained a replacement from my supplier, this one only lasted a couple of days! I was offered another replacement from my supplier but respectfully declined and ordered a different unit from another supplier. Again after only a week or so this one has also failed, my question is, am I missing something fundamental here or have I just been unlucky?
