trencheel303: if you check my January rainbow thread I've posted an extra pic in one of the comments comparing them three green wavelengths, where the colour differences are more real as seen with naked eyes
.
There were 2 reasons I haven't used 1W 808nm:
1) Safety. To shoot a rainbow of 100-200-300mW surely is a fun, but the eyes are what I care most for. Wearing OD7+ glasses covering the spectrum of 405nm-445-455nm-515nm-520nm-532nm was OK, but with the two reds on - 638nm and 660nm - it wasn't easy, closed eyes and/or looking through live mode screen with goggles on Nikon D5200 did the trick. Imagine invisible 1W of infrared on top of that... not easy to do, when it comes to safety.
2) I didn't have an extra 16340 battery left. All were used in the rest of the Skylaser line... will have to buy more, eventually:thinking:.
Tmack: Point well made:beer:. Especially breathing condensation trick makes a real wavelengths mixture magic.
Just a recap shot that reveals the actual set-up. The dull grey wall turned purple:shhh:.
