LED UV Light Box: Build Your Own for Under $150

[Paul Cunningham]

Slow going.

It took more than a day to accomplish this, but I have some good news to report. My original print times, when the box was new, were about 240 seconds, not bad. My new print times are now about 100 seconds faster at 140 seconds total duration.

A shill post, but does point to the ascendancy of LED as very useful lighting.

This new company caught my attention last week.

Based in Wisconsin, they seem to be making some parts in USA, not clear on the LED source.

I expect Heiland competition soon.

This is really interesting.

I built my own unit years ago from 24" T12 UV fluorescent bulbs. I made it about 22" by about 25", so that it was oversized for 16x20. I checked around on the internet to get dimensional information. For example, the 1.25" diameter bulbs are spaced 1/4" apart. It turned our really nice, it was painted, and it had a drawer/shelf that rolled out and back in for the artwork. What was hilarious, is that I had a separate ballast and circuit for each bulb. Took me months to finish. Hundreds of connections.

That said, are you sure that your LEDs strips are spaced closely enough, in comparison to the distance to the artwork? (Rhetorical question.) I notice that the light sources are closer together along the strip, than side-by-side.

I'm wondering what the spectra distribution of LED lights are, compared to that of the earlier tubes? Are they bright enough? (Rhetorical question.)

As a comment, it will need to be longer and wider than your largest piece of art, to avoid the light fall-off at the borders of the light source.

It occurs to me that you could have easily purchased a brand new one, if you had sold your Arca. (Probably would have had some cash left over.) (Just kidding.)

I expect Heiland competition soon.

I just emailed Jürgen to see if he's been thinking about it. My Nuarc works beautifully, but I'd love to go bigger.

I was checking out Amazon the morning and found this (there are several similar) that powers the LED strips. This is still inexpensive and provides some features that my power packs do not so if you want to try building one of these, check this power supply out.

I have this same power supply that I use for my drone battery charger. Its great in that it does duo power input but it is kind of just a box with wires attached and there may be better options. Cheep yess but no features.

I’ve been using this power supply in my UV box for the last several years. Works like a charm.

Randy, thanks for the tip. I emailed them asking about color characteristics such as CRI. Hopefully, I'll hear back. They might be a good source of product for all sorts of photographic purposes. I currently us a Chinese edge-lit panel in my 810 scanner, but it's be great to have a local source.

Thank Eric. I have searched many tutorials, and this is the one I expected
