I mostly like the pineapple, specifically for its nice tint. However, I have three complaints:
1. It's really under-powered with a AA battery. You have to use a 14500 to give it some useful output for outdoors. Inside, it's okay with a AA for most uses.
2. It's horribly unregulated. Output starts off okay with a full cell. But by the time that cell is half-drained, the output has dropped a lot. It's worse than any other AA light I have, by far.
3. PWM. Nasty, especially on low modes. The frequency should be much higher (or use current control).
That is based on my experience with the original pineapple. Perhaps they've improved it in later versions. For such a fancy light, they really should have used a better driver.
