Hi guys,
First time post here, here goes!
I have an old Speleo Technics Nova headlamp that I use for caving and would like to modify the battery pack. There's a thread on the exact light here - http://www.candlepowerforums.com/vb...5-Watt-LEDa-head-lamp&highlight=technics+nova.
I'm wondering if anyone could give me advice on the best battery setup to use. The light has a switching regulator that can take a maximum input of 5V to power the 5w Luxeon LED - the light switches output between 5 light levels depending on the voltage.
I could power it with a few 18650's in parallel but I wouldn't be getting the optimum light output with 3.7v. Is there a way to use a higher voltage battery combination that is limited to 5v or would this only waste energy in heat? Is there a 5v battery that would be more suitable?
I've a pretty basic understanding of electronics and lighting so any advice would be very welcome!
Thanks,
Eddie
