id like a low lumen (50-80) p60 dropin that will drain 3 x AA (derelight javelin) dry without turning off when voltage gets very low, is malkoff the only dropin that can do it or are there others?

If you can use less lumens, you can build one in about 10 minutes...
Uncertain about this application re: the OP's 3x AA request. I have found that 3x C alkalines yield blue-shift within seconds on my 5mm LED. I'm fairly certain 3x AA alkalines will provide the same result - severe overdriving of the LED. 3X NiMH (and their lower cell voltage under minimal loads) would work fine, but will provide only ~10 lumens or so.
2xAA would provide a number of options re: the inexpensive multimode low-voltage dropins such as SolarForce.
There really are very few adequate solutions for what the OP is looking for, aside from the Malkoffs. :thinking:

He could put a resistor in it right, lowering the voltage getting to the LED, and using a nichia, maybe get 25 lumens???
