Installing a Fluorescent light

In my 1 car garage, I only have 1 bare bulb light. Its barely enough to see in the garage, even with a 100-150watt bulb.

I would like to either install an outlet in exchange of the bulb fixture and hang 2 separate shop lights and plug them in, or hardwire an 8ft 4 bulb fixture.

Thing is, I still want to keep the bare bulb for winter, so its instant light, and the bulbs don't have to warm up.

If I hardwire a fixture, and I tap into the junction box above in the attic that has the bare bulb, do I run the NM-B right into the fluorescent fixture itself with a strain releif, or do I put a j-box in, and run wire through that?

why not just get yourself a couple of florescent cold start ballast fixtures. then you can eliminate the incandescent all together. Cold starts are good for as far as -20. That would be around -3 or so Fahrenheit i think. personally i would run armored cable if they're going to be hung from the ceiling with chain but romex would be fine if they're going to be mounted directly to ceiling and the cables run in the attic.


Sarcasm is my friend
I'm here to learn too, i do mostly commercial/industrial/new construction and this place is a great way to pick up tips on residential from some good electrical minds. Excuse the spelling, my phone has a mind of it's own.

I would also suggest cold start ballast fixtures. It gets pretty cold here and I have never had any start problems with them starting. No need for junction boxes with a fluorescent fixture most of them have knockouts to bring the cable directly into them.

Make sure that what ever light you decide to get regarding fluorescent that you get one that use T8 lamps, not T12. They stopped making T12 lamps last year. You can still buy them but when they are gone, then that could be a problem. T8 and T12 are t he diameter of the lamps.

Echo the need for T8 and check the ballasts carefully. If you need to, plug the ballast model number into a search to get the manufacturer specifications. You probably want a programmed-start ballast rather than instant start to spare the lamps.
