I'm still using the 7w incandescent red bulbs. Though my body is between the bulb and the film, I'm also fighting light leaks in my community darkroom. So, I generally use the SP10 covered for the first 3-4 minutes of development of single sided mammo film. I should try using it as a tray only and check for issues.
I find myself wondering if Infra Red lights and night vision goggles might not be the way to go for making film and developing.
About the time this thread started, I used X-ray film with an old red safelight bulb that came in one of those boxes of photo stuff we accumulate. No idea what it was or where it came from. It never fogged anything. It no longer works, thus my search for a new bulb. I tried one of those Viper night vision monoculars that were the rage on APUG. It fogged panchromatic film. I don’t remember the wavelengths involved, but the wavelength that doesn’t fog is invisible to the Viper. I suppose I’ll get it out and at least test for fog with X-ray film.
I bought today a Dental Safelight with KODAK GBX-2 filter made for Blue or Green sensitive X Ray film
Last decade we didn't know which KODAK filter was correct now eBay is dumping
This is the safelight I am using and I don't have any fogging issue but I keep the light at about 2 feet away from the film.

Camera: 8x10 Kodak Rochester Empire State made around 1920
Film: Agfa X-Ray exposed at ISO 100
Development: 6 mn in Caffenol C-H @ 20°C
I found KODAK GBX-2 / GBX2 (NEW IN BOX)
eBay
It sure looks like even dentists are dumping x-Ray
I never tried that safelight filter as I never heard of it until very recently
I will add several to my DR
Well those tricky eBayers
They had 2 FS one used one new, the used was 1/2 price
4 Days to here, Dentist wall mount, made for X-Ray

I have the SuperBrightLED bulbs, purchased about 3 years ago (I’ll look to see the wattage when I get a chance.). I was having fogging issues with Fuji HRU, so I tested. The lamp was about 6 ft from the film, pointed towards the ceiling, with a reflector dish around the bulb, so here should have been no direct light, only reflected. This was about 2 minutes exposure with a lens cap on the film:
Attachment 220767
I bought some rubylith gel, but I haven’t had a chance to attach and test it.

Just to recap this setup does not fog Fuji HRU even after 25 minutes of exposure. Kodak 1A in bullet, Lowes 1W LED (I think)
No fog with Ilford Commercial Ortho, either
Filter is seven feet from developer tray
Superbright have no markings, on both the old 1 watt and new 2 watt
They look identical, but one is way more powerful
Also the usual reflectors have heat holes near the base, which leak bright light
I cover those with gaff tape
