this may be a good idea for those who were looking for purple spot lights last year...
only thing is,
does that paint chip off due to the heat?
i know it's made for glass, but i would think the bulb would get pretty hot!
Keep in mind I only did this once for a show, but I'd have no problem doing it again. I may do it for my haunt this year. Maybe half and half on a spot lens.
I think it would work on an incandescent light too, because the same principle is involved.
Truthfully, I just used whatever glass paint Michael's had. Don't remember the brand, and I'm not sure it matters. I do remember I had to apply like three coats of it to get as dark a green as I needed, but that means it started off a light color if it helps you Bayou.
The type of Glass Paint I've used in the past is by Pébeo and is called Porcelaine 150. It requires baking (you can also air dry) so I can't imagine that the heat of the bulb would be a problem. I purchased it at Michaels. They make the paint in different transparencies, so keep any eye on the labels.
