Thanks for the replies.  I'll have to dig in there and see if the old one has anything on it.   

Do you think it will tell me voltage in/out and watts?

Got it, appreciate the input.  We have a bunch of huge skylights, it's like being outside in here, so we have to have a dark room, plus we would
need like a million cabinets to store screens so we had to build this one out. It's the long term storage/exposure that gets me, can be such
a hard thing to pinpoint, IE "maybe we could have gotten a little more detail out of that one". I guess I could image a high mesh screen and leave
it sitting for a couple weeks for testing.

Ya with sky lights you probably need to do it. Here we've left screens certainly for hours out, not normal thing but its happened. Without any noticeable affect.

We have LED Lights in our entire shop, high bay out in warehouse/print area and also normal LED in our offices. We coat/image/burn in direct light, no dark room here. We did mention to the light people the type of work we did and he did make a choice on light color but not sure what it is to be honest.

I just know we never have screen issues and I didn't want to mess around with a darkroom, our building doesn't really have a great spot for that.

Can you pull the old one and find the numbers on it?  It's probably half the price elsewhere.

Building out our new screen room, and wondering about work lighting. We've always used the UV blocking sleeves on fluorescent bulbs,
but I've always hated being under that weird yellow light.

It's a drop ceiling, and my thought was a couple of those drop in LED replacement panels. From what I've read, regular LED's emit almost no
UV light, and especially at a distance of 8 feet or so it shouldn't be an issue. My concern is long term accumulation, some of our higher mesh screens
may be sitting around a month or so.

Anyone have any real world experience with LED lighting in screen/storage rooms?
