The last I talked to Simon, I thought he was going to carry these, but a lot gets lost in translation. On top of that, Simon is taking care of his daughter full time and trying to run his business. He’s done a lot this year. Three new colored S2+, shorty tubes, the L2 and two new UV lights. There is only so such the man can do, but I’m impressed by what he’s accomplished this year.
Egg-zactly! We need to filter out that annoying visible light! I’ve wanted to do this for ages, but the only option, other than an expensive custom-fit filter was found on a page suggesting that I buy and break open an incandescent blacklight bulb and tape the broken glass over the light. :Sp
It appears inherent of 365nm led design that apart from the peak around 365nm there is a low intensity broad band of visible light (400nm leds do not have that, and I am testing an LG 385nm led at the moment and it also does not seem to have the problem). Only Nichia found a way to minimise this (but it is not completely absent).
So the visible light problem is not restricted to cheap leds (the expensive Ledengin 365nm led also puts out the whitish light), and a uv-pass filter just fixes it very effectively.
