Potentially useful LEDs for darkroom/alt applications

[Ron McElroy]

For anyone still looking for LED exposure units, the 100 watt Everbeam 365nm floods are back in stock at Amazon. I just ordered 4 of them.

I got my last 2 of 12, 50 watt 365nm yesterday

I think many want them for Hell-O-Ween

Still configuring, but very close to using 6 in close formation

Thought I'd post a shot of my little light box made using an Absolute reel from Waveform.

S11 LED Bulb - 7.5 Watt Equivalent LED Globe Bulb - 27 Lumens - Red

Just ordered 8 more for testing

They are cheap enough for anybody to self test

I am revamping my safelight environment to larger areas

A few years ago I bought an LED grow light to supplement the light in my orchid house during the winter - the Platinum Series P450 LED grow light, 450 watts. Its one of those lamps that gives a very intense pinkish light. Well, I retired my greenhouse 18 months ago (affordability issues - thanks pandemic) and so I have this $$$ grow light I have no use for. Until recently, that is. I started making Salt Prints of some 8x10 negatives and thought I would test this grow light to see if it could be useful in making Salt Prints. As it turns out, I can fully expose a Salt Print in 7-9 minutes under this light. Seems pretty good to me.

I wouldn't suggest anyone rush out and buy one of these for alt print making processes, but I wanted to share the fact that it does work very well.

When I bought the white LED reel from Waveform (see box above ~6,000 lumens, 5000k, continuous spectrum, super high Ra and Re, ie quality overkill), I added one of their red reels to my order out of curiosity. Their red has a relatively narrow band and might also lack the anomalous spikes that fog peoples' paper/films. I haven't done any safelight tests with it yet. I have 16 feet of it and a few inches are probably enough to light a darkroom LOL.

I might also get one of their amber reels and put a few inches behind my Kodak OC filter instead of the old incandescent bulb. Might help to increase the longevity of the filters.

Now that's an idea!

I now have a pile of KODAK Bullets, I love the Art Deco design, one will be my bed reading lamp, that will replace my DIY reflector below

Switching out the 15 watt incandescents will save the NOS KODAK filters

and I can use those bulbs in my fancy old contact printer

A short string of red led Christmas lights serve as my safe light since GE discontinued their Guide Lamp night lights.
I got 'em on clearance at CVS.

I have one of the 100w Everbeam's for 8x10 and it works well for Salt (and presumably other alt processes). Earlier in the year I purchased 8 of the 24" Barrina 395nm 9w T5 LEDs but the single Everbeam gives much shorter exposures.

How are you going to mount yours? I'm thinking of picking up at least 1 (possibly more) for larger negatives.

Nice. Those Waveform Absolute realUV strips look pretty cool (and available in 365nm), but looks to be more expensive than the Everbeam's. Visiting their web page, how many feet did you use for your light box?
