they started out making hunting spotlights, a system that had a scope mount bulb holder and a handheld bulb holder.
you could then fit one of three reflectors (140mm, 170mm and 240mm)
many in Australia loved the reach from the 240mm reflector on their hunting rig and started fitting them to the roo bars on their 4x4s.
the range has expanded quite a bit since I last looked at them - the battery powered units look quite good though, being able to unclip the battery and fit a curly 12v cord is nice.
