Rosco Roscolux Congo Blue, 20 x 24 inches Color Effects Lighting Filter

I bought this filter for making a pair of near-infrared goggles, and it works well for that purpose.Item arrived earlier than the estimate I was given, which is always a nice surprise. It did not come in a mailing tube (and it was very slightly creased at one end as a result), but I think that was because there needed to be room for a very nice full-color catalog of Full Compass Systems products. An acceptable sacrifice, for sure.

Our stage lights are a bit warmer in color temperature so the film looked more purple than blue. We used the film for an Easter play as part of a night scene with green light filters, the effect was stunning, also looked good for the flash of lightning effect.

just what i was looking for and a good size to cut several applications for . seem nice and thick so won't warp as bad as some f the thinner products out there from fixture heat

Great color, while still allowing for a good amount of light to pass through. Shipping was fast! Nice price

Exactly as described. Purchased to use as a blue film for a camera. Definitely recommend.

these filters are too weak. the orange is almost transparent with an orange hue. the congo blue is better but still doesn't compare to other brands. the red is probably ok.

In least for making infrared goggles.I don't know how well it would work for its intended usage but it worked very well for me.

Great quality!
