Some Metal Halide lights have 120V-480V multi tap transformers, I sell them in my store, they draw the same wattage regardless of which voltage you run them on.

Re: Shop Lights
 

To clarify. The H.I.D. lights put out the same wattage but require more amperage to operate the lower the operating voltage. Amperage is what spins the meter....

Amperage times voltage =====Wattage Wattage is what spins the meter not amperage, which is why your electric bill is read in KW not KA. 120V x 10A = 1200W 240V x 5A= 1200W 480V x 2.5A=1200W.

That is Ohms law. Watts/volts =amps

I thought Ohms is what you did when you crossed your legs and closed your eyes.

For High Output cold weather lamps and ballasts make friends with your local sign shop that specializes in illuminated signs. If they have a good relationship with their sign materials supplier the cost is much less than electrical supply house.
There are also LED lighting systems used in signs that put out more white light than you can imagine, if you like to build your own stuff.

Times 2 on that.

They may even have some fixtures that are practically scrap to them.

Look for the HO T12 rectangular pin lamps, at a minimum.

I use the T5

Re: Shop Lights
 

We spent a lot of time and probably too much money on this when we built our shop, but the results were great and I wouldn't change a thing.

40' x 52' shop with 96 4' T8s. 24 8' fixtures with 4 4' bulbs each. White ceilings and walls. After not finding anything to suit us at the big box stores, we spec'd these fixtures from an online lighting and design site. Our electrical guy ordered them at his supplier. The shades have perforations to get a percentage of the light on the ceiling and dispersed to help eliminate dark spots. We have them switched so that we can turn on as much as we need, where we need it. The front and rear rows are shaded toward the front and rear walls and the ends of the rows are near the side walls. Lighting on the benches and areas at the walls is excellent.

I constantly get fliers from Harbor Freight with coupons for these little flashlights, FREE! ( http://www.harborfreight.com/27-led-...ght-67227.html ) So I go in and redeem the the coupon... I think when I get to a couple hundred units, I will put them up in my "race car bay", for lighting.... It will be a pain in the *** to turn them all on and off, but WTF? They were free....... All this cold N. Illinois weather, gives me way to much time to think about this stuff...... ;-)
