Hi Boaz, would love the current list.
Updated list headed your way .
Stay tuned kids we’ve got another giveaway coming up soon.
Walks up to your trenchcoat self…“hey brother…you got that dc? I need a fix…”
For real though, could you send me a list of what you’ve got in stock?
1 Thank
Hi @Boaz .
I’ve got some 12V floodlights mounted outside on the house (for security lighting.) Do you have anything that will survive being outside (and on the outside of the lens) that can reduce 5700K down to around 3000K to 4500K ? I don’t want the beam spread changed too much either.
(I was going to pull them apart and do a LED swap, but they’re pretty well sealed and not coming apart.

The material is tough enough because it’s the zircon Amber sheets and they are much thicker and lots tougher . The sheets are cut 3” by 6” so you probably need a couple sheets .
Here’s the lee filter calculator which will help you decide which filter you’ll need to get to the temperature you’re interested in .
I carry 5 out of the 6 possible zircon ambers because two of them were so close visually I just picked the one I liked best . …
I carry the 806,807,808,813,814….the 809 is the one I didn’t buy .
Their most numbering system seems odd to me so I list them from lightest to darkest T-1 is the 814 and T-5 is the 806
Playing with the tint calculator is lots of fun and helps you get headed in the correct direction .
The filters are fixed and the led tint you begin with is always the wild card .
Tint is too personal for anyone to say what is right or what is wrong . The answer is to try multiple filters over your lights and let your eye tell yo when you’ve gotten what you’re looking for .
- again I stress having at least a few minus green filters in your bag of tricks since green issues plague led emitters and can be easily fixed .
I need a bigger raincoat .

Pssst … I got the stuff .
I’ll send u a pm

Hey, could you send me the current list?
Would it not make more sense to publish the current list in the sales thread?
Happy to do it ….
Pm sent !
Update list headed your way
There are numbers of lists in the thread . One at the original post and a couple mixed in the 600+ posts . But the one I send via Private Message has prices , my PayPal and some extra how to pay info .
At some point I’ll clean up this diffusion thread and the minus green thread , the giveaway threads , combine users pics and make a shorter version . Maybe easier to navigate .
For now … just Pm me and I’ll help any way I can .
2 Thanks
Heck yeah, thanks for doing this! Sending a PM!
Z2 Filter Increase in CRI with a TS10v2 4000K
I made a post about it on Reddit and thought I should post it here as well.
After installing it in my MAO TS10v2 4000K, I measured the light and was surprised by the reading.
So, I tested again with another TS10v2 and got the same result. The Z2 filter increased Ra and R9.
My guess is that removing the bump in the green on the spectrum helps to get closer to the target. R12 is still low, however.
Orange TS10v2 without a filter, and below with the Zircon 2 filter.
I have no idea how to read that…am I correct in assuming that the R9 values are as relative to its own light source? Or do they just get objectively higher with the zircons?
**for clarification…the “Spread” so to speak across the spectrum initially had low R9’s because of the relatively high values of green etc, and hammering out those green values through the filter brought up the RELATIVE R9? Like if you take out the outlier, the delta values decrease so the spread looks more even across the board?
Well, the most important things to look at are CCT, DUV, Ra (average R-values), and R9 (Red).
I believe you are correct, as my understanding is that the deviation from perfect color reproduction at the given CCT results in lower R values. Therefore, if a light source deviates from the reference curve of the light CCT (here 4000K), it will have lower R values for those colors.
So, I made some more measurements and redid the ones I already had to make sure the conditions were the same. The results show that up to a point, CRI will increase as the filter eliminates the outliers, and past that, it makes things worse.
Additionally, a low DUV can impact CRI, although it doesn’t have a direct effect. Using a Zircon 3 filter shifted the DUV to -0.0080, which didn’t seem to affect CRI, but further reduction might contribute to a decrease. This might explain why combining Z2 and Z3 filters lowers the CRI, unless it is due to overcorrecting outliers.
I measured sunlight to have a positive DUV of up to 0.0077, which, despite being a visibly very different tint, still falls within the acceptable range for CRI calculations. This could indicate that overcorrecting the outlier could be the cause for the lower CRI with Z2 & Z3 and not DUV being too low as it would be in the acceptable range to be considered white light.
