I use 4 Ni-MH in my quantum 2000, very similar set up to the Turtle. I think the Turtle is a bit brighter. I would suspect most 4 AA LED lights would be fine using Ni-MH or Ni-Cad.
When I run 4 Ni-MH in my light it pulls about 50mA per LED, with alkaline it was pulling 80mA. Supposedly they claim it is OK to run 80, but I like being able to use the rechargables and the LED's don't get so hot that way either. I did actually test the Quantum by running it on 4 D cells for over 2 days constant and didn't have any problems.
