We are thrilled to introduce our new Light Bulb Filter Films. They are sheets of film that measure 12.5" x 8" and come in different colors. They're lightly adhesive. You just cut a piece off and cover a lightbulb with the film, which will turn the color of the lightbulb to match the film! This is an awesome way to dramatically change the look of any room, party, light for a very small investment! Each film will cover about 4 standard size lightbulbs. Just cut with scissors! Energy Efficient CFL Bulbs up to 60 watt are recommended for use with the Color Gels.
