Would it be safe to drive a 1W Q4H from a 18650 Li+?
Or, should I use a resistor?
How about a 3W SY0J?
Or should I try higher Vf devices?
Heat sinking is only moderate, copper pipe.
The particularly interesting thing here is that the Luxeon voltage drop pretty much limits the amount of discharge of the lithium cell. Kinda self-limiting.
Any thoughts are welcome.
