So glad I found this thread! These little filters are very cool. I've had them about a week, and have already transformed several lights into more of a generally useable (& warmer) tint. I just hope they have the staying power to remain vibrant over time. I imagine if the lights are used on high less often, then the filter is less liklely to fade?
I certainly have no use for many of the primary colors, but have put many of the magenta/orange/pink/neutral hues' to good use. Most of the frosted and flame retardent filters aren't what I need, but the initial low cost paid for itself just with the ones I HAVE used so far!
If you're thinking about these....go for it, you can't lose .
