Hi all,
So, forging along after picking up some rudimentary soldering skills, cheap equipment from ebay, some PCB knowledge, rudimental understanding of MOSFETs, resistors, and capacitors started working on a simple MOSFET switch that is turned on by the M@g stock switch.
Fun so far with modding and now have picked up a used DC bench power supply from who else but ebay. My wife is beyond jealous now but it's still fun.
I've found out my 12v bulbs: 64625 flashed at 13.9v, 62138 flashed at 15.2ish volts, 64623 flashed just over 17v, 64458 took to 20.5v and it is hard to tell the difference between it and the monsterous 24v 64655 driven to the limits of my equipment which is 13amps @24v.
Only have 2 64458's so didn't take it to flash point.
Update on 64458's driven to 22.5v and held for few moments then with the next increase it instantflashed I would say between 22.5 and less than 23v.
Super white and hot, would be tricky to direct drive it on 17 cells although I've heard other doing so.
64610 flashed at 15.08v.
Bulbs connected via Kiu socket and measurements varified by DMD piggybacked to power supply which has an analog meter. For $50 I'll live with it since it has 13amps, 72v limit.
FM's new 3" reflector used pointed to ceiling. So brightness is my subjective impression.
Burn test(held piece of colored paper- actually a Hersy's wrapper to the rim of reflector) on the 138, 623, 625 are about the same taking some seconds to ignite.
64610 at 14.5v would draw smoke from the paper but not ignite.
Both 64458 and 64655 driven to above mentioned volts ignited the paper the instant it was at the rim of reflector.
Now for the liability statement you can get hunt playing with fire and electricity, water and electricity cause some really impressive results.
