Derek,
Thanks for sharing Swatch Book!
The New Swatch Book, Designer Edition, does not have page numbers.
Does anyone know of a different edition currently for sale that has page numbers?
The Swatch Book Designer Edition is arranged Per wavelength. Starting in the Ultra-Violets and progressing to the Infra-Reds, The diffusing films/fabrics, and then the Diffusion Foils and Reflective Films/Foils.
I will play around with it some and report back my results.
I guess for those that have a newer swatch book without page numbering, mention the approximate Wavelength section the filter is from.
Example: #100 Spring Yellow ~600nm or #332 Special Rose Pink ~700nm. This way those with and those without page numbers can find a particular filter much easier and faster.

....They don't have their limited-palette Zircon (high temperature) gel filter swatch book listed on their website, but I e-mailed them, and they sent me one for free. This Zircon swatch book has (so far) five "Minus Green" filters, six "Warm Amber" filters, and three "Diffusion filters"...
They are still listed on the siteApparently the Zircon swatch book is no longer available. There are various Zircon sampler "packs" of 12" x 12"sheets here:

The best, quickest way to getting a throwy light with color would be to pick one you already like and just add the proper filter to get the color you're after. It's actually way better than letting a manufacturer choose your color for you, as you can go warmer, cooler, more or less saturated depending on your tastes and not someone else's.Does anyone sell LED throw flashlights that come with a Red, Green or Blue beam?

Filtering will not increase the CRI. Filtering lowers certain color temperatures to make a light more aesthetically pleasing. The main point is You may have a light You really like but hate the tint, and filtering can help. Most LED lights last many years and great percentage of the older one's are still in service.I noticed this thread dates from nearly 10 years ago. At this point there are any number of LEDs available in all color temperatures with CRIs at least in the low 90s. Given that, I question the point of filtering. Maybe it can fix small variations around the margins, but that's assuming the correct filter exists. But honestly, almost nobody would be able to tell CRI 93 from CRI 98, assuming a filter could get you from 93 to 98.
Thanks for keeping up with this after all these years. I've had so many emitters swapped but have a modded E1L that for some reason was determined to be too difficult and I couldn't stand the light coming out of it. Now thanks to some minus green it's become one of my favorite lights to reach for.I found the Lee Zircon filter # 802, which is approx. equivalent to minus 1/4 green, to be nearly perfect for filtering ALL my Zebralights. Zircon #803 would be approx equivalent to minus 1/8 green.
I've updated the first post in this thread with the new info. Happy filtering : )
Yes, it's an old thread with still usable information. There are lots of emitter choices. Apparently you didn't read the pertinent parts of the thread or you would have understood better the reasons that some of us have been using the filters and the fact that you can do much more than fixing "small variations around the margins." Seems you're also confused as to the differences between CRI and output color. The first has nothing to do with this thread and the second is the primary focus of it.I noticed this thread dates from nearly 10 years ago.

My first instinct if I had a light I liked but hated the tint would be to swap out the emitter. That's doubly true if it's an older light. Swapping out the emitter for a modern, more efficient one could give 5x to 10x the output for a really old light. Moreover, emitters are dirt cheap nowadays compared to what they cost in the past.Filtering will not increase the CRI.

It's a long thread, so no, I didn't read most of it. My general take is that LEDs have improved vastly since this thread was started, both in terms of tint and CRI. Tint seems to be more a preference than anything else, so I get that part of it. Even modern LEDs may not have a tint you like because they're designed to mostly be on the BBL. Some people prefer a light source which is slightly off the BBL. Filters let you get something which isn't manufactured. I'm not really that sensitive to tints unless it's noticeably extreme. Bluish or aqua tints bother me the least. Purple tints bother me the most. Green is somewhere in between.Yes, it's an old thread with still usable information. There are lots of emitter choices.

You may well be hyper sensitive to green tint. Note that one person's "white" can easily be someone else's green or purple or blue tint. I've heard the lens of your eyes yellows with age. A light which seemed blue in your youth might now seem perfectly white.jtr1962,
Just because an LED has a high CRI rating and nice color temperature doesn't necessarily mean it will have a pleasing tint. Color temperature and tint are two different animals, color temp is the variation between red/yellow and cyan/blue, while tint is the variation between green and magenta.
I have 4 lights that have CRI ratings above 90, and every single one of them has a greenish tint. When I place the proper level of magenta filter over them (or minus green if you prefer that nomenclature), they suddenly become extremely beautiful to my eye, with nearly perfect white beams and wonderful color rendering.
I believe I'm hyper sensitive to any green tint from my many years as a professional color printer, where I printed wedding photos all day long, and believe me, you don't want any hint of green in flesh tones, as it tends to make folks look a bit sickly.
Many folks don't mind a bit of green tint, because it can actually make outdoor foliage look rather nice, but for me, it's a no go. And yes, I've got two lights that specifically have Nichia 219b LEDs at 4500k , and they still appear just a bit green to my eye. But once I put a filter on them, then WOW, the green tint is gone and the colors just pop, and I'm a happy camper.
Hey, if you'd like to try some of this Zircon filter material for yourself, just PM me your address and I'll slip a small piece of Zircon 802 in the mail to you. You just might become a convert :twothumbs
