My LEDs are these:

An update on this. I ordered eight of the lamps Fred links to just above, from the source he linked to (the shipping was more than the cost of the eight lamps at 69 cents each). They arrived yesterday and I proceeded to try them out in a little-used Electron Beam. One of the red ones was intermittent (I'll contact the seller about that). The other red one and the clear ones all gave me current draws on continuity indications between 30 and 38 mA on fairly fresh AAs. They are plenty bright.
Now that EB and my original Solar Launch Controller are Q2G2-safe with much less hassle than the LED mod I did to another EB, but since the lamp protrudes from the EB and is quite a bit smaller in diameter than the hole it's in, it feels a little precarious. The Solar controller's lamp well is much deeper, so no issue there. On a semi-related note, I also recently purchased a Pratt Hobbies FullBoost handheld controller, which uses EIGHT AA cells. It uses a beeper and draws very little current, but a Q2G2 on 12V fires INSTANTLY when you push the button .
