Is the skylight UV blocking?

I do not know for sure, but Per the Eplastics website The ePlastics OnLine Plexiglass acrylic plastic sheets including the Bronze and Gray acrylic solar control shades. - Note that the color, solar energy, and transmission values do NOT change with thickness.

I purchased the dark tinted skylight and strongly assume it does block some uv light. I have not tested it to be certain.

I'm not sure if they block all UV and Blue rays, but they are awesome especially for the price. I look at a computer screen at work constantly and when my eyes start to hurt, I put them on and it really helps. They are nice looking too.

As for UV protection it is comparable to both the Sun Mountain and the Gustbuster UV versions. I've used both.

No, there is just enough light to be comfortable. Very adequate for blocking out the sun.

Barely. It's inhibited by a layer of some sort that keeps the light from coming straight through.

No, 99.3% of the UV produced by the bulbs is blocked for safety. Vitamin D from Sun exposure is due to the UV and bright light therapy is believed to work through the bright light hitting the retina and causing changes in the actions of the pineal gland. Please make sure to check legitimate medical sources for more detail and authorative information.

The works with sunlight and long time in black UV light. Best with sunlight. Will work both behind a window and outside.

I think it may depend on the color you chose. I bought the wheat and covered a pergola roof and made curtains with it. At night you can see a few stars and the moon. during the day the sun does shine through but it blocks enough that it doesn't blind you if you look at it. I've heard others say that the darker colors will provide more shade but depending on the grade you purchase it my not provide as much uv protection. The curtains have folds in them so they block more light. However I really like being able to pull them flat and see the sunset in the evening. If you want total block, Coolaroo won't do it alone. You'll probably need to use some sort of backing material. You could double the layers and they might be enough with some of the darker colors but not with the wheat. Hope this helps.

Yes. It completely blocks out the light.I hang it in front of my garage window.

Except for the one umbrella that's SUPPOSE to block sun, they're all translucent . . .so they will diffuse the sun, but not block it. The one umbrella that's opaque and called a "sun block" does shade, but because the shiny side is underneath, light is reflected back up into the face, so is not a good "sun blocker". If you can see the upper section of an umbrella from beneath (as shown in the picture to your left) it does not block the sun . . .only diffuses it.

It blocks out the sun great- you may want to remove it in the evening if you need to look through that window for turning out on to a street street see if cars are coming, that's my only complaint: In low light situations before people put on their lights, it is tough to see through

i put mine in and i dont have a reflector on mine it works fine i would think that it would block some of the uv light

Love it in the sun, need it in the rain! Yes, our JoeShade UV blocking umbrella also blocks the rain. It's a "Full Service" umbrella. Thanks for asking. "Stay Cool"

You CANNOT see the UV light. When the UV light is engaged, there is a bright blue indicator light. However, this is not the UV light. The blue indicator light will not damage your eyes or skin. The actual UV lightbulb is mostly protected from exposure inside the filter's housing. I believe the warning in the instructions refers to viewing the light when the purifier is disassembled.

I always have a UV or skylight filter mounted on my Canon lenses, purely as protection for the lens from either dust or damage. The hood can be screwed directly onto the filter and it does not effect your pictures.

Yes, it is my understanding that it has everything to do withe the intensity of the light. It is not providing any UVA or UVB rays which might be filtered out by glasses. I wear my glasses while I sit next to my Happy Light and read or work on my computer. So does my mother.

I don't think so...it is a mesh material, not total sunblock, like a black out curtain.
