Hi! Could anyone help me find two LED's that are between 5-10 watts?
Try BestHongKong.com or even DealExtreme.
They need to be very bright
They'll be bright, just compare them to 75mW LED's
and preferably the standard light color. (not blue, red, green, etc...)
Standard light color??
Assuming you mean white by that, you still need to define the color of the white, as they come in a wide range of "whites", from very bluish white to a very yellowish white (more yellow than an incandescent lamp).
The bluish whites are the most efficient, but with them, color recognition sucks big time.
