so what do people think of this hard but easy task at hand by creating this little green box.

[i_am_Doug]

...Its a brown box.

[BlazinFire47]

indeed, very brown may it be, green like a lightsaber, glow it does.......

we just ignored the entire chassis mod/creating a box, and just stuck ours directly to the back of the HDPE sheet.

Took about 15 minutes instead of 2-3 hours :)

What type of PSU did you hook the box up to. How many volts too, we finished the box, but our leader is a bit scared that we might fry it. Whom ever tells us the PSU and the Voltage thanks, its greatly apreciated.

Whom ever tells us the PSU and the Voltage thanks, its greatly apreciated. I tested one of the assemblies and it draws 650ma when cold and as I recall got to 800ma after about 5 minutes running, I also tried both 14v (typical 12 volt supply) and a 12v gel cell, Not a big difference in current. So to sum up 4 times 800ma gets you 3.2 amps at 12 to 14 volts So a 3.5 amp or greater 12v (14v) supply should be fine don't forget a in-line fuse unless you supply is auto sensing of a short or over load.

A quick solution to get your camera calibrated, but how's it going to stand up to constant shelling from poof balls? :ahh:

My team actually built a really nice box from some 2x4s and plywood. I'll bring my camera and take pictures tomorrow if I remeber to...

[Doug G]

We built ours much the same way, a 2x4 frame, some sheet aluminum on the back, but it just doesn't seem bright enough. We may try lining the inside with foil next.

At first outs was extremely dim, after about 3 minutes it got brighter, then I walked down to the wood shop to get some tools, and when i got back about 10-15 minutes later, it was very bright. I believe that the lights just need to worm up..

Our box took about an hour to make and about 30 minutes to wire. I wired it up to one of our 12v batteries and used a breaker panel from 2 years ago and a 20amp fuse to power it.

I was just wondering if anyone else used the correct offset for the lights from the diffuser panel?

Also, ours was plenty bright with just wood, has anyone compared a wood box to the official boxes to see how the light compares?

[AV_guy007]

we used aluminum and a 12v battery and it was bright almost instantly :) . i dont think they have to warm up.

[skimoose]

cold cathodes do need to warm up for maximum light output.

4 hours of work? i can understand taking your time, but you had nothing better to do?
