Wiring Bulk Head Lights

VincentW · Nov 30, 2016

Apologies for what will seem a daft question to you guys - I am not an electrician, and have not got to grips with the different voltages on appliances.

Can someone tell me if these lights can be wired into the mains - these state 110v so if not would these usually be powered by a generator or transformer.

Again apologies for my lack of knowledge.

If you stick 230V it will damage the light as well as being extremely dangerous, where did you get the fittings from? so DON'T connect them up to the 230v mains

We have these in our warehouse - quite a large amount, so how would they be powered please.

Sorry to be obvious, but they need to be powered from a 110volt AC or DC supply!

If you only have UK (230VAC) mains then you'll need a transformer to reduce the voltage from 230 to 110 volts.

I believe construction usually use 110v (I may be wrong), so where would use a bulkhead emergency light like this ? I think its an emergency light anyway - although it does not have a battery of any sort inside

could be emergency lights powered from an external 110V source. e.g. a battery pack.

Thats what I thought, however what makes them emergency lights as opposed to standard 110v bulkheads if they are powered from an external source surely a normal bulkhead would work the same

Has it got a capacitor inside? EDIT: A big one.

if they are emergencies, on loss of the lighting circuit supply, the emergency supply would kick in. 110V would mean less batteries to supply them.

Some older emergency light systems have a central battery instead of batteries in the lights. Ones I have seen in the past have been the size of a tea chest if you are looking for one on site.

Vincent can you show us a picture of the packing and any instructions

tetctrix may have hit on it. Some emergeny lighting systems have a central (battery) supply for all emergency lights.
Standard voltages are 24, 50, 110 and 230Volt

They'll be powered by something that looks like this:

The packing is just a plain brown box - ive sent over a pic of the inside PCB

What was your intended use for these fittings Vincent, or are you just trying to find out what they are ?
