Friend, colleague and fellow blogger Kevin Willmorth, principal of Lumenique, performed an interesting experiment recently to produce an LED PAR lamp with a light pattern somewhere between an R20 spot and a PAR20 flood, with an R20 flood’s light output.
He produced his own LED lamp using spare parts from a halogen PAR20, CFL, 4W 120VAC LED device, a spare LED heat sink, and some epoxy … and got surprisingly good results considering its Frankenstein construction.
