Wiring Question


Hello there, im looking for a little help.

Im planning on building a box, which is going to consist of a row of about 7 or 8 75w flood lights, kind of similar to the Red/Yellow/Green lights you would see at a dragrace track...except they will all go on/off at the same time.

What would be the best way to wire them?

Thanks.

I would just use surface bell boxes piped together with EMT and a premade cord and a cord connector in the last box.

Hey thanks for getting back to me!!

By premade wire, what exactly do you mean? Do you have an example you could show me?

Also were you suggesting they be wired in series?

I have some electrical knowledge,im in now way a specialist, but im a real quick learner.

Wiring Question


W/P j box




Hub cover



lamp holder





Connect the boxes with threaded nipples.





Run a pigtail into the back of the first box.



Attach the green wire to the ground screw on the first box. Attach black/whire wires thru boxes to lights.


Attach a deck flange via threaded nipple to the bottom box and screw it down to something big enough to support your light set.

running series or parallel.... one way if one light burns out, they all go, the other, if one dies, the others stay lit. pretty sure you'd prefer the latter.... with bulbs in a box, you'd have heat buildup to consider as well. perhaps if you drew up a sketch of what you want to build and post it, we could help more. =o)

Thanks for all the help. Yeah the only advantage to the series is..its easier, but yeah I definitely don't want any lights to go out and kill the rest.

As far as the box goes the lights will be on the outside, so there really wont be any place for the heat to build up.

Thanks for the help guys. If i have any more questions ill ask away.

This is not true you can wire it as series. Not the correct way and lights will be dim the more lights the more dim.

OK, so let's get technical. All 120v lighting wired correctly will be in parallel.

That's because it IS true.
If you wire in series then it is NOT 120v lighting anymore.

8-120 volt, 75 watt lights wired in series, would only give you about 10 watts of lighting.

Wiring Question


Should every light have its own cord cap, or can I group them together? Like say 2 groups of 4 lights, or 4 groups of 2 lights, with each group splitting off from a central line with its own end cap.
