emergency light

yes you are correct the battery will be knackered no doubt....I'll just pull out the innards and use the case for something .....

the fitting instructions say 1992....but looks like new very old stock...waste of ?4

It comes on when you have a power cut and/or the consumer unit is tripped.

It depends on which version has been purchased. Some models just side illuminate a piece of perspex with an fire exit logo. Other models are like bulkhead light fitting (approx 10W LED ) with an option of exit and running man stickers.

It doesn't necessarily have to indicate an emergency exit. If the stickers are not fitted it can be used as general purpose emergency lighting to, say, illuminate your stairs. Maybe a good idea to fit if someone has mobility problems so they can see what they are doing during a power cut or as I have done to also illuminate the consumer unit if the lighting has tripped.

I have two in the house (one in the cupboard under the stairs where the CU is, the other in the cupboard above the upstairs where the UPS and IT kit is, that's a maintained one operated by a wardrobe switch, so as as you open the door, it comes on) and one in the shed.

The last one I got from CPC was switchable between maintained/non-maintained by a wire link, the LED ones are noticeably brighter than the T5(?) fluoro ones.

We have 2 "Nightsearcher" torches which can be configured in such a way as to live on their trickle chargers and come on when the power fails. One lives in the hall and the other beside my bed. When the power fails here, if there's no moonlight you quite literally cannot tell if your eyes are open or shut; or at least you couldn't until I bought the torches.

Living here without emergency lighting would be very foolish.

Yep, very handy, keep your 1st call standby stuff there as well. Another place is above the stairs, so you don't fall down 'em, or misjudge when you are at the bottom in the pitch dark of a power cut.

Bought one with the intention of using it in maintained mode in the windowless boiler/meters/CUs room. Unfortunately it's "cool white" which I hate, so have a warm white LED bulb and the emrgency light in non-maintained mode.

Are there any "warm white" LED maintained emergency lights?

A pack of 100 warm LEDs from aliexpress for £2 and an evening's de-/re- soldering?

How long do intend to stay in a windowless room in the company of the boiler, meters and consumer unit? Surely it doesn't matter in that location what the colour temperature for the light?

In real emergency a cool white may actually cut through smoke etc. better than a warmer colour temperature.

Is it water proof?

em may be shower proof under a bulkhead..why?

It doesn't, the French used yellow headlights because they gave better visbility in fog/rain.

NT

have they not stopped that now? ....

Probably not because warm white LEDs are less efficient, so you need higher power to achieve the light output.

Before you get too excited, do check it works. It's probably been removed from an installation because battery has got to replace-by date, and it's cheaper to replace the whole thing than it is to get replacement batteries.

Such units can actually continue working fine, *providing* the unit hasn't been left unpowered for a long time with the battery flat.

Wire it up to charge for 24 hours, and then let it run for 3 hours. If it dies significantly before 3 hours, probably not worth using, although a couple of charge/discharge cycles might revive it.

Well if its non maintained, then you can use it for emergency lighting and that is about it ;-)

Close to the CU is handy should you need to reset a MCB/RCD without lights.

TLC do the replacement batteries for some types...

I was wondering if it could be used to make a submarine for bored hamsters.

It would make a nice change for them instead of running around in a wheel all night.
