LeeFilters Swatch Book for $.01 from LeeFiltersUSA

That’s a great price! A local dealer sells it for 20 euros… too bad you can’t order from Lee internationally.

At least Thomann has it a bit cheaper at 7 euros

Don’t worry djozz. I actually ordered two (max allowed). Once I get mine, you can have one of the swatch books. Just cover the shipping from Denmark.

This is not bad either https://www.rfsystems.nl/shop//artikelen/lee-filter-swatchbook-designers-frlexxt10.htm

Nice find!
That’s a good deal for us in EU :slight_smile:

I ordered two books there, one for work (school), one for me. But thanks for the offer Valor! :slight_smile:

I’ll gladly take the extra one and pay for your troubles since djozz already ordered his. :slight_smile:

Very interested to measure how the minus green filters work.

Deal:)

Their Zircon range would probably be more effective since it’s designed with LEDs in mind.

Maukka,
The filters finally arrived from US. Are you still interested in one?
I will need find out how much the shipping is from DK to FI.

regards,
Val

Sure, I’ll hit you with a pm.

What does it do? Excuse my ignorance.

It is a sample book with all the colour filters that Lee produces. These filters are usually used for theater lighting, in front of a spotlight.
Use for flashlights is limited, you can create and alter tints with them, at the cost of light output. The sample filters in this book are large enough for most smaller flashlights. For me it is a nice thing to have, but I will probably not use it much for anything.

Got the Lee filter samples from Valor today. Tried it with a diffused Xiaomi USB light, that has a greenish tint (gets worse with higher output modes). Measured on the highest of the five modes.

The diffusing filters (a lot of different kinds) also seem very cool.

Three different minus green filters tested: minus eighth, quarter and half.

Light loss
No filter: 100 %
1/8: 88.8 %
1/4: 83.8 %
1/2: 73.7 %

Color temperature shifts a bit lower with the filters. Here’s the CRI data.

No filter

1/8 minus green

1/4 minus green

1/2 minus green

Holy moly…I’m glad I sent you those filters.
I’m really curious what your test setup is?
Care to tell a bit more about your intstruments? :slight_smile:

I’m using an X-rite i1Pro with BabelColor CT&A and just Excel for the CIE chromaticity plot from the xy-coordinate data given by CT&A.

Cool, thanks!..I wonder if a cheaper X-rite ColorMunki Display could be used for similar test… :nerd_face:

I can recommend the i1Display Pro and the free Argyll commandline software. I use those two to do my runtime graphs. The spotread program bundled in the Argyll package gives you the color temperature and xy-coordinates for tint, but you would need a spectrophotometer for CRI data and spectral distribution. Don’t have experience with the ColorMunki, but it looks simliar to the i1Display Pro, which is not that much more expensive.

I will look into it :wink:

Ordered some sheets of Lee Zircon filters. Six 61x61cm sheets were 40 euros. They’re supposed to handle heat better. I got the minus green filters in three variations, 803, 804 and 805.

Here they are installed in front of the Olight S1 Mini CW. Normal minus green filters are included. The 804 and 803 Zircon filters are better at retaining the color temperature while just moving the tint towards the BBL. However, they can’t be used to correct a severe green tint. Also would have wanted the stronger 802, but it wasn’t available.

Here’s the relative output (click links for CRI data):
No filter : 100%
Zircon 803 : 79.9%
Zircon 804 : 83.6%
Zircon 805 : 86.6%
279 -Eighth : 87.2%
249 -Quarter : 81.5%
248 -Half : 71.5%

Also, finally got my Acebeam X45 to be what it was supposed to be from the factory. Excellet CRI, great warmish tint with acceptable shift thanks to the sliced XHP70s. Also, no tint shift between modes, just CCT shift. Green on the lower modes is very common on Crees.

Of course, this is all at the cost of output. It’s now at about 50% compared to stock.
