I see in alot of the old space footage the Apollo era 'nauts using cool little lights. About 6P in size and really cool looking. Anyone have any info on the old space age lights?

wonder what the runtime was?

During flight, Apollo vehicles used pure O2 at about 5 psi. The suits used pure O2 at about 3.8 psi. The shuttle and ISS use 20% oxygen 80% nitrogen at 14.7 psi.Not sure if they used oxygen or an air mixture for the flight itself, they stopped testing at pressure with pure oxygen after Apollo 1...
Nyctophiliac, I think I read somewhere that NASA uses Photon Microlights, and US astronauts gave some as gifts to Russian Cosmonauts. I think that may be on LRI's website. I'm not sure what other lights they might use. I'd be interested in finding out as well.
