Hi, I was wondering has any one had problems with Eterna LED 3 hour maintained emergency exit lights?
Most of my work is inspecting and servicing fire and emergency lighting systems, and carrying out any required replacements or repairs.
Since last march, I have fitted a lot of Eterna LED maintained exit lights, and during the next few months, the maintained side has failed, leaving the fitting basically a non maintained fitting. Theres a test button on the bottom, which still works to test, the link between perm and switched feed is fitted correctly, and the voltages are ok.
I have spoken to another electrician who had the same problem, within a month, with 2 fittings, but a lot of sparks that I know, just install and walk away, and might never be back on the same job, therefore they will never know if these fittings fail. I return to my jobs every 6 or 12 months for inspections, and i'm concerned that i'm going to be failing a lot of my own lights!
Has any of you guys returned to an emergency lighting job and noticed any problems?

Thanks Micky

Welcome to the forum.

Eterna are a mid to low range make and you may find a percentage of the products do not make the grade.
Failures after a period are always hard to deal with as opposed to immediate failure that is just a nuisance.
I would expect that since LED is still rather in its early youth and maintained fittings are on all the time that the circuit for the LED driver on the 230V side has failed a similar problem to cheap GU10 LED.
Unfortunately if the percentage failure rate is high then you may need to move up to a more reliable brand.
