Hi there Brad, just thought I’d shine some “light” on why you are having this issue with the dimmer. (I’m a theatre lighting Technician) Due to the design of the electronics within the dimmer, even when the output is set to 0 there is still a small amount of current flowing through the devices connected to the outputs. The resistance of the filament in the mini gem is enough to dissipate the current without the fixture producing visible light. However this current is enough to partially operate the switch mode power supply that the laser uses. Also a side note: The polarity on the input side of the switch mode power supply is universal, so often times the factories in China don’t bother getting their labelling correct.
