Heatsink is too small for zero duty cycle.

depending on diode efficiency & lens about 1.3A ~ 1.6A

M140 diode will work for this kit? I messaged the seller for details however have had no reply

My M140 445nm diode is running at 1.62A. I have not properly metered it yet, but when I put it on the LPM just briefly the other night it easily hit 1.2W with a 3 element lens.

M140 diode will work in this kit. You can add copper diode module and copper heatsink, but I don't think you will ever get it to a continuous duty cycle.

Which host would be good for a zero duty cycle running at ~ 1.4W?
