Dang, that's cool. And your login name makes a lot more sense now. The sintra would be awesome for making a 4-bank. My only solution at the moment is to tie to fixtures together with aluminum straps. It'll work, but it ain't pretty.

:) I'll take functional over pretty anyday....just like I prefer my women. :)
 
but the light bulbs are 40 and 40 W right?

80 W is not all that bright me thinks, is it possible to see a still or osme footage using these home made kino's?
 
A 40W T-12 flo produces the same light as a 120 (or is it 160?) watt incandescent. So, yeah, you do need a fair number of light, but I've gotten decent results with just the three 2-banks I currently have. Only have boring focus chart footage the moment, though. If I turned those 2-banks into 4-banks, I think I'd be pretty well set. Also, I'm using an M2 35mm adapter, so I need more light than a standard DVX.
 
I am reviving this thread, because I need the info on if I can pick up the necessary parts from Home Depot or similar..."Zoomforce"???
 
've been using T8 bulbs in my DIY fluorescents. I bought a box of 24 Philips TL950's at 5000K and 98CRI (local electrical supplier, $140 CAN).

The T8's are 32 watts, and more efficient than T12's at 40watts, both in terms of power, and lumens.

The ballasts from my two tube fixtures ($20 on sale from Canadian Tire) are electronic, and dead quiet. No issues so far with interference.

Also, every T12 fixture I have seen comes with magnetic ballasts. Its usually only the T8's that use electronic.

A 40-watt fluo ostensibly puts out as many lumens as a 150-watt tungsten bulb. However, the light pattern is much different: fluo's are inherently soft, with very quick light falloff. A bare tungsten bulb is extremely hard with very little falloff.

So comparative output is dependent on how far away you are from the light...

Yes, but a bare bulb gives you a rather ugly light, so you have to diffuse it somehow, and then the falloff goes shorter too. So it's pretty much useless on most situations, except fo lighting a scenery.

Well, that's what I think at least.
 
Home Depot no longer sells this fixture, and the replacement looks nothing like the original "Commercial Electric Shoplight". to me....Any Ideas??

I just got the shoplight fixture yesterday. You are right, they arent selling them at home depot, but the LOA shoplight is on sale at Lowes still. I got mine there for about $17. Home depot has the best selection of bulbs though.
 
A question I thought about yesterday: will an electronic ballast work with any fluo tube, if the wattage is not exceeded?

I mean a 36W electronic ballast will work with say a 30W fluo tube? Or the tube has to be a high frequency type?
 


How about a square or rectangular bank of CFLs? You could wire them to turn on in rows, much like dimming.

What are the drawbacks, as opposed to making these long flourescents, oh "shadetree-engineers" of the internet?????

I would think they would be smaller and more protectable when transporting,.. can't say anythinga bout the light output.

Give me feedback!

And also, when buying flouros for this purpose, what temperature should they be rated at to get as close to possible to natural light?

Anybody have any ideas on expanding this original design to accompany 4-bank? I know the only housing you can buy at Home Depot or Lowes is a 2-bank.
