Just a quick observation,
there is talk of wanting it to be for 1s, 2s and 4s cell configuration, this would mean the battery tube would have to be made in two parts, one for 1s4p, 2s2p or 4s1p and an extension for 4s2p or 2s4p.
Not a problem design wise but how about cost :question:
Personally I would like a good thrower that I can use, not a pencil beam for bragging
I don’t know what y’all light up at 500m+ but with me, it’s usually wildlife or sometimes unwelcome people or a car. So 3-5m of beam width would be perfect in comparison to say a wide beam with more lumens from the xhp that would be wide enough to light up an area as big as a house or two.
The OP has the diameter already spec'd at 120mm. Does that mean that a specific reflector has already been chosen? Sure would like to hear about it as it will about the biggest differentiater from other thrower lights.
