Hey guys, i'm hearing that the lowest you should run the A140's is 400 MA, does anyone know about how much optical output that will translate to? I want to run it as low as possible, for the sake of beam quality and the fact that I have no desire to carry a 1w 445 around. But I do want that frequency. :(

hey man,
i have a chrome pen build at 420mA and its doing 250mW, ive also got a trustfire TR-801 with a problem driver (the driver was meant to output 1200mA which is around 900mW) but it LPM's at 200mW so i imagine less than 400mA is where they become unstable.

Oh right on, thanks! How do you like the beam on that pen build? Is it overkill?

yeah its not bad, the beam on these diodes seem a lot cleaner at lower powers.

Oh great! Thank you! So is that just for the A140's? Are there simple formulas for estimating output from PHRs? Or red diodes?
