Workshop Lighting question


I have a workshop that only has one light fixture. I got an adaptor to screw in the fixture with a receptical plug on it. I was going to get some of the 4 foot flourescent fixtures that you can plug in. Each fixture has 2 40 watt bulbs. I was going to get a power strip or surge protector and try to use 3 of the fixtures.
Would that be too much running through the one light fixture the plugs are going to?

Thanks

Probably not, but it is a hack way to install the needed lighting. Some can also say it is unsafe including me.
Use the cable that supplies the existing fixture for the new lighting circuit. Remove the fixture and see the box it is mounted too. There should be some knock outs if it is a metal box, or some holes if plastic.
Insert your new cable into the box and make up the connections. White to white, black to black and bare to bare or green to green.
Then feed each light individualy with more cable as needed. You can also jump from light to light, your call. Throw that screw in base receptacle away.

The problem isn't the power draw, it's the installation method. Running things from extension cords isn't the best way to do things.

You wouldn't be the first one to do it though.

Workshop Lighting question


So if I run the lights by hooking up the wires directly and jump light to light, could that wire from that one fixture run 2 drop in lights with 4 40watt flourescents in each fixture?

Thanks

Yes.

The circuit will handle appx 1800 watts and you are likely well below that. You are only adding 120 watts.

edit....adding 240 watts

edit again.....160 watts.....but you are taking out the existing whatever watts. You will be fine as long as you use approved wiring methods and make you connections properly.

Wouldn't it be 320 watts since he is using 2 lights with 4 40 watt bulbs in each(2x4=8x40=320)?

Sorry, I did change from the original post. I figured if I was going to run the wire I might as well just hang 2 with 4 bulbs each instead of 3 with 2 bulbs each.

Workshop Lighting question


How big is your working area? Have you considered 96" inch fixtures. They run about $30 - $50 each. Cover much more area and use just a tad more power.
I know it is tempting when you see 40 watt fixtures for less than $10.00.

Note: Ballast replacement cost is usually more than the fixture cost. I bought some 96" fixtures ($30.00) and when I needed a ballast they were close to $50.00 each.

Your call. I just go for the 96" in every workshop setting. Your area is small, so it's up to you. Good luck.

Absolutely! I had some 96" magnetic ballast twin flourescents in my unfinished basement. When I went to replace the bad ballast, I found at HomeD magnetic ballasts for about $28, electronic for about $39 and a totally new fixture with electronic ballast for $32. Amazing how the sum of the parts are far more expensive than the whole!
