12V Bayonet Lamps

[mpsrdf]

Hi all

 

Does anyone know if you can get a 12V lamp that will plug straight into a standard mains Bayonet lamp holder?

 

Regards

I know you can get 24v lamps that do. The old central-battery emergency lighting system we had at the local theatre used them before it was upgraded to the more modern self-contained fluorescent type.

One question: WHY? Could an inverter not do what you need to do?

Try car spares/accesories shops, I think 12v 50w GLS bulbs for car inspection lamps are quite common, though I'm not 100% sure if BC or ES is the more common cap.......

Halfords do them - they have 12v inspection lamps that take them.

 

Dont bother looking in the lamps section - go to the workshop tools bit, and they are in there. They are usually made by ring lighting.

 

They are half the price of cpc etc.

conservation of energy I thinks is the posh name.If you've a 24 volt backup battery your also going to need a 24v charging circuit ,so why not make the load 24v,no need to convert back to 240v.and loose something in the convertion,and older inventors weren't the most efficient,
