420ma Will give you around ~300mW give or take. the duty cycle would be 1 minute on, 1 minute off for maximum diode longevity. Cr123 Batteries will give you a good long battery life.Rangedunits said:I dont has cr123& chargers;( how much mW? Runtime?

250mW of red is still one helluva hot laser. You can kick it up a bit by getting a glass lens for it, but 300mW isn't realistic.jayrob said:I've built a lot of long open can diodes at 420mA's. I have had a couple that did 300mW's at this current with a Meredith glass lens. But most of them need about 430mA's to reach 300mW's. This is with the Meredith glass lens.
Using an AixiZ acrylic, you can expect about 245mW's (on the average) at 420mA's...
