Great product, I was surprised how easy it was to use, I used mine to block a laser beam for photography and it worked a treat!

Small Liquid Crystal Light Valve - Controllable Shutter Glass
I've never seen anything like this before, It's crazy. It is normally like a glass ( tilted, not clear) and then with each voltage increase, It goes darker and it really does block a lot of light at 5V. I think it's a must have, even if you dont use it much, It. Is. Just. Super. Cool. :D

Small Liquid Crystal Light Valve - Controllable Shutter Glass
This Light Valve was as good as I expected. It allows about 50% of light transmission when 0V to 1V is applied (maximum brightness), then between about 1V and 5V it reduces light transmission to about 2% (maximum darkness). It was interesting that transmission stays restricted for about 30s when voltage is removed unless a low voltage is applied to cause the change to become instantaneous. The darkening was slightly mottled rather than being optically pure and even, but this was not a big issue.
