The T20C XP-G R5 has quite resonable throw for the size of the head. The Lumintop TD15 series lights have a much deeper reflector, for greater throw.Here, the T20C is brighter coz it's a newer R5, but boy Sunwaymen have short throws?
It's true that most of the high-output Sunwayman lights (like the M40C, M60R, etc.) are not particularly throwy. That is because Sunwayman opted to go with shallower reflectors (for wider spill but less throw). :shrug:
But that's the nice thing about having so many choices to choose from - you can always find something somewhere that matches your needs.
