Well I wired my first 10 watt LED today Not as hard as I first thought, thanks to a good tut and other members with knowledgeable answers. However, I am at somewhat of a loss to see the difference in brightness between a blue LEDengin 10 watt, and a Blue Seoul P4 LED.
Of course I set aside my bias (I dig upon P4's big time ) in order to go to a 10watt blue. But I'm still kind of scratching my head. At first I thought my focal length was off, so I switched lenses. It seemed to help, but over all I can't see much of a difference. I also tried different blades with different amounts of diffuser. Both 7/8 and 1" stock. What I notice in almost every case was the brunt of the LED's brightness seemed to be 3-6 from the emitter, dimming as it reached the tip of the blade.
Where a P4 and a Rebel seems to maintain a brightness evenly to the tip.
I will have pics soon, both of the wiring on the LED and what the blades look like.
Perhaps someone could shed some light on this for me? (aw man pun intended )
