UPDATE 200802: Color Mixing Problem
Tested some lights and found problems in mixed configuration. The 16mm lens can’t mix the color properly, resulting in odd looking beam. Only E17A module combined with 70° lens has acceptable beam (still not perfect to my eyes). Those with single color selection don’t have this problem.
The number in each corner represents the LED configuration on the MCPCB. Distance to the wall = 20cm. Shot with ultra HDR to mimic real human view.
The solution are:
- Change the module to E17A. Not perfect, but usable with the widest optic. The picture above shows 3000K + 4000K E17A module, not too visible due to relatively close color difference. In person, you can still see the faint orange diagonal band across the beam. But those with wider range, for example 2000K + 6500K, would be visible. Please make the change no later than 200810, otherwise I will solder the LED as ordered.
- Use special Gaggione color mixing TIR lens. Tested, and the beam was perfect! But unfortunately I can’t show the picture since the only sample left was destroyed when I tried to trim it to fit inside H04RC. I already ordered 50pcs medium and 50pcs wide. This lens is very expensive for the size but it’s the ultimate cure for the problem. Trimmed and modified to fit H04RC I ask for $3,7/pc.
