Correcting \'too green\' Luxeons

Gentle Friends,

An intersting thread on this topic was started over on the LED forum by a member who found a filter material that corrected the color making it 'more white'.

It ended up with my buying a large sheet, cutting it up and offering it to CPF members who would send me a self addressed, stamped envelope. I still have plenty of material, it seems to me that some here might be interested?

Re: Correcting \'too green\' Luxeons

OK, folks, the last piece is 'spoken for', the SASEs are coming in, the first minusgreen filters ship tomorrow.

Thanks to all involved, I hope they report back here on their results.

The first 8 pieces are on their way to their new (hopefully happy) owners.

Re: Correcting \'too green\' Luxeons

I received my piece of "minusgreen" from Mr. Owen yesterday and THANK YOU VERY MUCH Doug! I have a slightly green but bright L4. Let me say I much prefer SLIGHTLY green way more than the sickly blue/violet most KL1's and KL3's are known for. I wanted to try some to experiment with the L4. I can tell you, this stuff is amazing! It totally cleared out any green and turned the beam just about pure white! /ubbthreads/images/graemlins/grin.gif Now there is a slight penalty and with my naked eyes I can tell the brightness is not what it is without the minusgreen. It's not a great difference but it's there. I'm sorry but I don't have a light meter to measure the difference and have no web picture host and can't post pictures. All I can say is if green LS's bug you, try this stuff and you'll be amazed. One more thing, this stuff doesn't come with any sticky backing like WriteRight. What I did on the L4 is I used a piece of minusgreen slightly smaller than the lens and then went over that with a piece of crystal clear WriteRight that covered the whole lens.

Thanks Doug

I tried the 1/8th minus green on my TL-3 LED and 3AA SL Lux (both slightly green). Big improvement. There Is a noticeable drop in brightness, but not bad for the color inhancement.

Re: Correcting \'too green\' Luxeons

Doug-can you wet the surface going against the lens, and make it stick decently ?

Re: Correcting \'too green\' Luxeons

Glad folks are having good results with the 1/8 minusgreen. I'm gald I went that way, rather than the 1/2 minusgreen, as nobody wants to take out more photons than necessary.

I like the idea of weting the surface, but think water might be a bad choice as it will dry out. How about mineral oil?
