I intend to try LEDs, and think you should try them first. . .The real safelight is very very dark, so I don't even bother to use it.

It's confirmed when I looked at the dry neg this morning, absolutely no fog from standard amber safelight, so the ektascan can be opened in the darkroom no problem! Awesome now I can cut some 4x5 and actually see what the heck I am doing! So glad to finally have access to a darkroom!

I use Kodak T-MAT G/RA Xray film and I load and develop them with a "normal" red bulb safelight at about 1 meter, it's a bit dim but no fog at all.

Red LED is the best, they have a sharp cutoff. On the side of my Ektascan box, it has a safe light symbol and the words 'Kodak LED, GBX-2' now I google that and find.

GBX-2 is no longer recommended, Kodak LED is.

Notice the wavelength specs. They are the same as the cheap LED's I have all over my darkroom from.

That site is the cheapest and that bulb is great. I put them in old Kodak bullet safe lights without a filter, makes them directional, at 48" no fog and I can see everything.

I've tried to point my red LEDs directly at the film at about 5cm for several seconds while developing and nothing happened. No fog at all.

I have noticed no fogging of paper or X-Ray film using these LED bulbs. I keep the darkroom rather bright with one on each station. And since these use only 1.9 watts per bulb, I nearly never turn them off.

Today, while I was on the site, I ordered a big Red LED flood bulb for my shooting area, so I can bounce it off the white ceiling when using a lens without a shutter. Pull the darkslide and pop the strobes.

Where do you guys buy your safelights? I have an 11 watt red bulb from freestyle but a 1.9 watt safelight bulb sounds better lol

I have never had issues with cheap 160 LED wee light and twice folded red gel sheet ;) But then i used it like few times for Xray film (use it all the time with collodion and for silver printing though) .. Still like to load film in darkness. Makes it more intimate ;)

My models like a red room...
