I’m surprised I haven’t seen anyone mod their LT1 like this yet. I don’t think there would be compatibility issues with the driver running emitters with different forward voltages on the different channels. The mixing ratios would be a bit off, though.
If the LT1m goes with a similar driver architecture, it also should be possible there.
I’d love to get an accessory kit for my big LT1, also as the battery case is just like many soda can lights another accessory could be a choice of light heads turning the LT1 into a flashlight, maybe 3x xhp70.2 for a flood style and a single reflector sbt90.2 for a throw type head. Yes I’m interested in a mini LT1.
