I have the Kodak GBX-2 filter which is advertised for use with X-ray film.
THE problem is the new improved 2 Watt red LED
When we first bought them they were 1 watt
Nothing written in the box or LED
I just found a NIB 1 Watt as I bought the originals by the box
double trouble
Jason told me either 1A or XRAY filter with RED LED No probs at all. Put it together and test it!Quote:

What type and wattage are you using with the Kodak filter?
At what distance, is it bounced or direct?
It is good the filter is still sold, I had a handful of damaged old ones, pinholes and worse
Kodak GBX-2 Dark Red Safelight Filter 5.5" for Blue-Sensitive X-ray Film & Green-Sensitive Medical X-ray Film
I just ordered one, I have several KODAK Bullet fixtures with 1 Watt Red LED, bounced off ceiling
I think an incandescent white 15 watt bulb was specified
Oven Bulbs!
I measured the direct light distance to make sure it was not under six feet. About 7 feet or so direct.
I suspect strongly I was told to get; what Jason linked me at the time was the older one watt variety.
The light is bright enough over the dev tray to lift the film up and clearly examine the shadows; straight replenished Microdol-X about 18 minutes typical

I have the 15-watt bulb that came with the kodak fixture. It’s still good. Kodak says a 25-watt bulb can be used indirectly.
My tests this morning were with the leds bounced off the ceiling.

KODAK Safelight Filter #GBX-2, 5 1/2' Round Size, for Blue Sensitive X-Ray Films & Green Sensitive Medical X-Ray Films.
Universal safelighting for both intraoral and extraoral dental filmsThe GBX-2 (ruby red) safelight filter is a universal safelight filter that can be used in dental darkrooms where both intraoral and extraoral films are processed. A frosted bulb of 15 watts or less should be used in the safelight, which should be at least 4 feet (1.2 m) from the film.The GBX-2 safelight filter may be used in darkrooms where manual processing is performed, provided that film handling under safelight conditions is limited to approximately 2 1/2 minutes.
