[PSUBS-MAILIST] LED lights

[Alan via Personal_Submersibles]

Brian,
I have had at least 7 blow on me, but off higher voltage.
It may be that the load is on & the current surges in, or if there are adjustable
pots they may be set too high.
On higher powered lithium battery power supplies to motor controllers they quite
often have a pre charge resistor ( forget the other name for it) .
This lets charge trickle in & fill up the capacitors before full power is
put on the circuit. I have this on my 48V lithium battery pack, so does Hugh.
Alan.

I guess my reasoning for staying with incandescent was that it was a no brainier for me but I liked what I heard about LED. I initially figured that if 10 lumans is good 10,000 is much better but I am finding out that once you get up to that high a luman, a lot of things kick in that you have to deal with!
