I have a few very useful lamps and light-emitting objects. I wear a RovyVon Aurora A7 keychain light on a bead chain around my neck 24/7. It has a handful of light levels for the main LED at the front, from 3 lumens to 650 lumens. (The older 550 lumen version had a smaller battery and a dazzler strobe on the main LED that the updated 650 lumen version does not have.) There is a lantern-mode white light on the side that has 3 functions: low, high, and a flasher mode. There's also a side-mounted UV LED (purple, "black" light). The shell of the flashlight is glow-in-the-dark blue, and is "charged up" by the UV light. When you turn off the light the case glows bright enough to see what you're doing. I find it works great for a night light that doesn't wreck my night vision, but if critters are going to be attracted to it, that may not be ideal. NEBO makes a little keychain light, the MYCRO. It has several brightness settings for the main white LED, but also has a separate RGB diode that they have set to give green or red. They're both very low light level, probably around 1 lumen, but it's enough to see by. Both are charged using microUSB and have fairly short charge times. They're both seriously durable as well.
I also plan to experiment with electro-luminescent wire. I have a nice length in white and one in red. The red is particularly nice, bright enough to see and even read by. Stretch it out where you need light, turn on the inverter on the battery box, and there you go, light. My only concern is that inverter. I haven't checked to see where it's emitting the worst noise, but I would expect it to give off some amount of RF noise somewhere, so it might not be ideal for radio operating, depending on where on the spectrum that noise falls. It might be low enough and on frequencies that won't matter to Amateur use, but I can't say for sure as I haven't tested to see where the birdies are chirping. The benefit is flexibility, relatively good light output, and low cost. The potential issues are in the necessity for a high-voltage inverter that could put some nasty hash somewhere we don't want it to. It might be shieldable, I don't know. Anyone test such stuff for noise output?
