Why use luxeon K2 star when you can use Gullwing form for high power led? They're about 1/4 of the price.
I want to build a high power led project which use a lot of LED. At futureelectronics.com, the gullwing form is 2.50$, while the K2 star is 9.50$. Specs reveals that the gullwing form is not insulated and should be, but that doesn't seems to be such a hard task, is it? Also, people with high-power led instructable seem to prefer K2 star.
Am I missing something here?
