red light is required during the astronomy nights, if someone uses white light they get a quick reminder to turn it off
led lamps use pulses vs dc current to save battery, but that will require a bit of circuitry perhaps not worth the effort given the elegant simplicity of your lamp
one more thing is tape red fluorecent light tubes to the tripod legs, it helps prevent kicking accidentally and also finding it if you walk away more than a couple steps
Thank you, Armando. The pulse would be nice, but it could be a bit tricky to make the whole circuit small enough to go into this particular housing.
Also, thank you for the advice of using the fluorescent red tube on the tripod. That would also work when I use the tripod along the street or on the sidewalk. In that case, the phosphorescent tapes (not necessarily red) would work, too.
