This is from Dave in the what's new thread:
"The drop down and limits are not changing much from the V2. The constraints are heating based for the flood.
Any emitter can run for 60 seconds at a level programmed above the drop down level.
The limits for programming are:
Flood: 1700mA
Reflector: 1500mA
Spot: 1800mA
There is no change from the V1 and V2 lights in terms of daily use. Just like before these limits are marginally safe. If you stick with the default programming you do not need to be concerned with heat, the light takes care of itself. If you go up from the default programming then please watch how hot the light gets! if it is uncomfortable to hold please let it cool off.
Cheers
Dave"
But I think there might be a more detailed manual coming out in the future.
