I had my cheap 5mw diodes wired in parallel and I turned the power down pretty low before I hooked up my red. The part that has me baffled is the 5 mw diodes barely got warm at full power so I figured if I was careful with my adjustments it would be ok but it went from "on" to led in a bump...

I know the saying "you get what you pay for" but I'm a frugal slow learner. I bought a couple of these cheap eBay drivers with the intent of running 2 diodes off one at about 5 volts. The description was pretty vague, but they were cheap so I scooped them. Well, I led'd 2 of my good diodes...

Good point. I'm sure the red will handle quite a bit more. I've read about folks here pushing them up to 450. But I'm not trying to kill it before I put it in my host so I wont give it too much. I've also looked at the datasheets on the flat ir and its about maxed already. If I go any higher...

Thanks! I'll have to mess with it when I get home from work tonight. I dont plan on pushing them (at least the red) too hard but i want to at least be able to get close.

The test load components were 4 4007 diodes in series and two half ohm resistors series. All the components listed in the first post were just the driver. I set it up based on the attached pic. But if youre saying a 5 ohm resistor as the current set will give me 250mA then I'll play around with...

I built my own driver so I can play around with a bunch of diodes I hacked out of lightscribe drives. I have a flat package 790? (Near ir at least) with a standard glass aixiz lens and an open can red with a g2, both smoking an old shoe over 10 feet away. Pretty awesome for a n00b imo, but when...

Lets try this again... I've been lurking here for a couple months gathering as much info as I can. This started (for me) as research on burning lasers for a mini dvd drive reprap cnc engraver I'm building and quickly spiraled into tuned cavity 445nm 10 watt fire starting cat hair singing...
