Anyone have got one of this? I took a close look at the LED module in a store, it seems that the only thing on the board is the LEDs. I don't even see any resistor on the board, and this is a 4AA light! Are these LED running on 6V unregulated or did I miss the resistors? I'm looking to buying this light. I just want to make sure that the LED is at least resistored.
Let me answer my own question. I've just bought a petzl duo LED. I have removed the LED module to take a look. I find some SMD resistor on in. So yes, the LED is resistored.
