Paul.... you blew the meter off it's 199.9 mW/cm² scale. That's a "bit" of improvement over your first units ~2 years ago reading like about 10!

Hold the meter at "face distance" away from the LED array (about 2" ?) and hopefully the reading will show on the LCD.

Todd.... That "1" display on the meter means "over-range". The full scale 199.9 mW/cm² for the same 10 minutes would be 0.199 W/cm² x 600 sec = 119.9 J/cm² fyi.
