Since it is just a prototype to find out how large of an area I can cover with a 100W IR led, I just need to make it work for a few minutes at the time. I'm not too concerned with durability etc. If anybody has a really simple solution, that would be perfect...
Can you cite a reference to that? 100mW from an IR LED will not cause blindness as far as I know
No, docedison said 100mW would cause blindness. I'd like some evidence of that.
So far this seems to be the simplest solution: "Use a MOSFET to switch it but drive the gate high/low with a second transistor".Will this work?
Any more suggestions on how to make a simple prototype?
