...whats the pro lab choice these days for a light box to put film over to view with a loupe? thanks in advance.....what would someone like Richard Photo Lab In L.A. use for example......need to buy one...thanks in advance
I've had a Hall Production unit for over 20 years now. It has the original lights and I use it weekly for MF & LF image viewing. The unit I have is very large. Made more for lots of 35mm at one time I suspect. I bought it new and it was a bit pricey, but they now have a 12" & 18" models. My unit is 40" long. They're still making them to this day as near as I can tell. http://www.hallpro.com/
Professional labs involved with critical print reproduction would (and do) use profiled and colour-/temperature corrected LED lightboxes/tables. Some cost a few thousand, while others look like they've been in use for decades. And the good old hobbyist make-do of an old shoebox with a single white lamp inside can still be found popping up occasionally at kerbside clean-outs!
For many years I used a tiny A4 sized LED light-table originally intended for art and craft use (Gepe made it I think). It became very blue over time and was disposed of in 2009. The studio light table now is a heavy, red-cancelling (~therefore, images with red/pink appear paler), flat panel LIGHTPAD 940 (940 lumens — more than enough to light up the entire studio and tan my dial to boot!) made by Art-O-Graph. My brother built an angled wooden table with a rubber top, upon which the light-table sits so I don't have to hover directly above, but assume a comfortable seated viewing position. The light-table is teamed up with a Cabin 8x 6x6 / 6x7 wide-field asph. loupé (plastic loupés are definitely not recommended for critical assessment). It's possible to make your own LED lightbox using LED strips if you have a creative electronic mind.
You can also use an iPad/Android tablet with a lightbox app installed. This is extremely handy for on-the-fly assessment when you're travelling. I use such an app on both my Galaxy tablet and LG phone. Brilliant!
I have the same thing as Mattking and I also find very useful. I store it upright beside the enlarger in my darkroom so it hardly uses any space. It's large enough for a print-file sheet with negatives. Also inspecting the glass negative carrier with the negative for dust is easy on this "light box".

Dimming is a rather new feature. I guess it makes sense with a very bright box and varying viewing situations as in strong lit rooms/outdoors vs. darkroom work.
