This thing allows you to use inexpensive color gel filters on yourLED accent PAR38 spotlights for the holidays.

My home has a bank of accent spotlights. In past years, I've used expensive ($20) colored halogen bulbs. I've recently updated the spotlights to LED and they run so much cooler I figured I can add cheap gel filters instead of buying dedicated bulbs. (I can't find colored LED spotlights anyway!)

The holder should fit any PAR38 bulb. If you stick with halogen, you'll need a filament that can take the heat!

Post-Printing

After printing the frame and 4 brackets (I placed them inside the frame for printing), glue the brackets to the frame. There is a center-guide to align the brackets.

Cut the color gel filters to 6" square (or a little less) and slide into the corner slits.

Outside, place the back clip on the bulb and bend the frame to place the other clips.

I found the green too white, so I combined blue + yellow gels.
