Indigon, I really enjoy your posts about Lee filters, thanks for sharing your experience
>I've had good luck with the older V2 & V3 HDS XPG & XP-G2 (Angry Blue-Green tint as Hogo mentioned) by using a Lee filter #162 Amber
thats a HDS 140?
if so, the #162 Lee, would make it an HDS 109 lumen model (High Cri in the pics is a 100 lumen model)
> My new 219B 4500°k HiCRI which I like a lot (slightly) enhances the colors, particularly the reds and browns, but they are not the true colors as I see them in daylight, the colors are actually a little richer at night with this 219B 4500°k.
I agree it oversaturates.. gotta take the good with the bad.. Id rather see a stronger red, than a brownish red. I do not use any Lee filters on my N219b 4500k 9080 LEDs
> Next I tried experimenting with the Goblin-Yellow-Green beam corona on my 4k XP-L but that's another story.. (Hint: #506 Marlene).
If that is a HDS 325 Lumen, after the filter it drops to 219 lumens (within 10% of a HDS 200 High CRI 219b 4500)
maukka recently bought an HDS 200 lumen 3oClock High, 5000k 219c High CRI
he added a
Lee 803 and raised the R9 from 67, to R9 95!
the 803 filter (79.9% light transmission) would drop 200 lumens to 160 lumens
the Lee 803 is a high temperature version approximately similar in light transmission to the Lee 1/4 minus green, that I use on my 3000k 219c. It would drop an HDS 200 3000k to HDS 165 lumens
I like to use 1/2 minus green on my Low CRI 6000k Cool White beams, that I find too yellow/green:
It would drop an HDS 250 to HDS 180 lumens
It would drop an HDS 325 to HDS 234 lumens. I recommend the 1/4 minus green for being Rosyer than Marlene, and 5% brighter.
I was skeptical that a filter could actually Raise CRI, but it does, at the cost of lumens from 20% to 33%, depending on the filters in this post. That is similar to the change in Lumens when HDS Low CRi 250, is upgraded to High CRI 200, a drop of 20%. or stated inversely, the HDS 250 low CRI is 25% brighter than the HDS 200 High CRI
I use Lee 1/8 minus green to reduce the yellowness of my N219b 4000k 9080
it would make an HDS 200 into an HDS 173 lumen
I like Lee filters, they help fix lights whose tint I find too green or also the ones I find too yellow. Almost as good as an LED swap, similar loss in lumens, similar improvement in CRI, but easier

example of the effect of 1/2 minus green on one of my very green Beams. the Novatac is the unfiltered reference, it has less green tint than the RRT-01 Magnetic Rotary on the left
no filter:
1/4 minus green filter on the RRT-01 only:
