A swatch book of light filters is a nice-to-have in an arsenal of a flashlight modder.
In case someone wants to grab one, LeeFilters USA has designer swatch books on sale for $0.01 (normal price $2)

International shipping might make this less of deal for us in europe 
Back at 2 bux now.
Remember to use the coupon āSWATCHā (as it states on the page)
What are the size of the films?
Valor, how did you enter an international address? The available address fields did not let me do that.
I gave up. I had to use my US addressā¦
From the images around internet the size seems to be around 4cm x 8cm (1.5ā x 3ā)
but donāt quote me on it 
Thatās a great price! A local dealer sells it for 20 eurosā¦ too bad you canāt order from Lee internationally.
Donāt 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!
Thatās a good deal for us in EU
I ordered two books there, one for work (school), one for me. But thanks for the offer Valor!
Iāll gladly take the extra one and pay for your troubles since djozz already ordered his.
Very interested to measure how the minus green filters work.
Deal:)
Their Zircon range would probably be more effective since itās 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, Iāll 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. Hereās the CRI data.
No filter
1/8 minus green
1/4 minus green
1/2 minus green
