old driving lights for a shop light ?

I have a couple of driving lights that I,ve had for years and never installed them. I thought they would make a good flood light for the shop. I have lots of 12 volt power supplies but the light just says 12 volts halogen but nothing for amps or anything else. I looked online but nothing came up. I want to hook to 110 shop wiring

If you know the wattage you can do the math and determine amperage

Re: old driving lights for a shop light ?

standard wattage should be about 55

watts = volts * amps, so watts / volts = amps.

55w/12v = 4.58a

I thought about doing something similar. I had one bulb go out and replaced them both so they would match, so I still had a good working one. Wasn't sure the best way to mount it for a work light. Figured it was going to be more work than it was worth considering the LED lights you can get nowadays.

Might be easier if you use fog lights as they have built in mounting brackets.

This is a joke right ? You can't plug a 12 volt bulb into a 110 outlet . The most you'll get is a flash as it overloads

Re: old driving lights for a shop light ?

You would need a DC converter. Power brick, wall brick, whatever you call it. 12v converters are somewhat common, but 4.5 amps is a lot. Might be able to use a laptop power supply. Voltage would need to be 15v or less to avoid burning out the bulb. Amperage can be higher than needed. It will only pull the amps it needs.

Part #2 is how you will mount the bulb so it is usable. if you plan to have it in the same location always, you should be able to just cut a hole in a piece of wood and mount it. Having it portable gets a little more difficult.

Oh yes, they would be easy to mount up.

In my calculation I used 55W, but that should be what EACH bulb pulls, so you would want something capable of more like 9-10a.

Might go for something like this:
https://www.amazon.com/ABN-Car-Power...rds=12v+10+amp

Wire the lights up to a lighter plug so you can power it from the car if needed.

Re: old driving lights for a shop light ?

Thanks RPM. Like I said before ,I hate throwing out good stuff . I clean out my garage and end up going back thinking of a way to use it. It,s winter here so I have to keep my self busy. Have a bunch to do on the trucks but most involves painting . a couple weeks and the days get longer. Looking forward to that instead of Xmas.
