I finally managed to save up and get myself a 50mW rated spartan which arrived on 2/14/17 and from the beginning noticed it dims VERY quickly. Most runs have it dimming at around 30 seconds into the run.
I am wondering whether this is completely normal for these when rated 50mW or whether I should contact Gary at DL and try to work something out.
This is a very nice wavelength but at the same time is very pricey for a unit that won't hold it's rated power for more than half it's rated duty cycle. Especially bothers me seeing most of these units tended to peak much higher than rated then settle at or above the rated power for the remaining duty cycle.
Attached is a power graph.
Ambient temp for this was 65F laser temp was 75F. Battery is an IMR unprotected cell fresh off the charger. Temperature was measured with an IR thermometer.
