Strip lights

[Elsa TLC]

Hello Sparks

Working at a school.
3 separate lights in separate rooms has stopped working.

The PIR clicks but no light. Switch does nothing either..

Any ideas?

Could I nick a part off another light.

The light seems to be an emergency fluorescent fitting which has been converted to LED, the fluorescent needed a high strike voltage which can damage LED, and most conversions were designed for wire wound ballasts not electronic ballasts, as the electronic ballast made the fluorescent nearly as efficient as LED so no point. I know there were some conversions designed for electronic ballasts, but not many.

So I would be looking at proper LED fittings, not a conversion, to test one could easily destroy the meter, as some high voltages and also often the ballast is designed to shut down with no load.

Step one is to find out what emergency fittings are required.

Link the sensor out to prove the lights are ok.

No it isn't, those are Ansell Oxford LED fittings

The red LED suggests the emergency light has failed its self test. Best way is to test for power at both the permanent and switched live terminals at the light.

Sorry missed it.

There may be an emergency light test switch , usually for a group of EMs. Make sure that someone hasnt operated the test switch.
You'll need a "fish" key for this...

No it's a new money wasting fitting

My personal experience would be to return the rooms to fluo fittings for long term reliability and cost saving.

I am sure you are right, but getting a fluorescent tube is getting harder, and the LED tubes don't give out as much light, and are unlikely to work with HF fittings, and most emergency fittings are also HF fittings.

I agree there was no real advantage swapping arsenic for mercury they are both nasty and both very little used in the lamp. So we simply have to do what politicians say. Be it balcony solar or LED lights.

But where I volunteer I am registered as an electrician, and in an emergency I am allowed to do electrician work, but in the main it is not considered part of my remit, as I have not kept updated since 2008, so only when the updated electricians are not available do I step in.

So if @Elsa TLC is taking the units home after being changed then good on you, for not seeing them wasted, and it is likely you can do some repairs/swapping of components. But is at your place of work, and you're not an electrician, then I would be wary of doing any experiments or alterations.

If after altering the fitting does not last the required time before battery goes flat, there could be health and safety beaches you are unaware off. Including lack of insurance cover.
