I just bought a 15W LED 445-450nm LED laser module from eBay:
“High Power 15W 15000mw Blue Laser Head Diode Engraving Module For Engraver”
There are no instruction at all included but I have it setup and working. I am just not sure how high the PWM can be set. The only information from the seller is:
Output Power: pulse 15W average 8W
Modulation frequency: ttl can be modulated
Does anyone have one of these and know if you must keep the PWM duty cycle < 53% (8 watts out of the maximum of 15 watts) or if the laser module manages the power level to keep it at or below 8 watts and you need to run it at a 100% duty cycle for full power?
So far running it at 50% seems only slightly more powerful than my 2.5W LED laser :-(
Thanks so much!
