Hi! I have some halogen light fixtures that came with our house when it was new. Once, when changing a bulb, I accidentally misplaced a circular glass fixture. I wanted to see if I could track down a replacement. I took a picture of one of the remaining ones. It appears to read "UV-001." Would this Optivex UV Glass Filter be a suitable replacement? It's an MR16 type fixture.
By Jacob from Pegasus Lighting on December 7, 2012
Yes, this should be a good replacement. Select our smallest size designed for MR16 lamps.

Hello, I'm interesting on this filter 5,4 inch , just 2 question, which is the temperature max (about) and is a filter for all uv a/b/c (sorry for my ignorance in uv range) ?
P.s. Do you shipping to Italy?
By Pegasus Lighting on February 26, 2014
It filters 99% for all UV radiation below 400 nanometers in wavelength. That includes UV A/B/C.
This item is made of glass, so it has to be very hot for it to cause damage.
Yes, we ship to Italy.

How do they attach to the existing fixture?
By Jacob from Pegasus Lighting on March 12, 2014
Generally the fixtures will have clips for attaching. If the fixtures do not, then the manufacturer may have an accessory that will allow the clips to attach. For MR16 light bulbs, we offer a clip accessory - http://www.pegasuslighting.com/clip-on-holder.html

I have halogen track lighting with glass UV filters. If I hold my transition lenses eyeglasses up to the light, the lens darkens leading me to assume that the glass filter is not filtering out the UV radiation. Will the Optivex filter, block the UV radiation that is turning my transitions lenses dark.
By Pegasus Lighting on December 27, 2014
Answer:Mark, these UV filters UV blocking exceeds 99% for all radiation below 400 nanometers in wavelength.
I do not know how sensitive transition lenses are or what amount of UV triggers them but I do know that they don't transition in the car because of the windshield filtering UV. My expectation is that the Optivex filters would be adequate to prevent the glasses from transitioning.
