Strange TwinSonic Dome that i've never seen before

[zappel]

I have 2 domes here that i have never seen before.
Usually the domes are not patterned. Can someone tell me something about it.

Are they clear domes with an interior sticker/coating? Looks like they are muting the light output a bit so it makes me wonder if these were used in the movie industry. They used several ways to dull the pop or brightness of lights to make them more camera and visual friendly.

Colored domes with a clear insert would likely be more universal now that I am thinking of it a bit more. Interesting find either way.

Yes you are right. I removed a dome and you can see a foil inside. Thanks for the quick tip.
