I bought a photography table tent a few weeks ago and a pair of tabletop LED lights to use with it. The lights were very inexpensive so I didn’t expect very much from them, but they produce quite a bit of light and are small and easy to use. The lights came with blue and yellow plastic filters that fit over the light, but let’s face it, I’m never satisfied with just two colors of art supplies! Are you?
So immediately I went looking online to see what else I could find — never mind the fact that I have no immediate use for these things. The filter gels, which is what they’re called, averaged about $12 for a sheet, but my lights are very small and I don’t have a need for a large square filter. I found a Roscolux sample book and ordered that. If I could cut out one of the samples and fit it over my lights, that would be great, but if not then at least I would have actual samples of the gel colors. Then, if I want to buy larger sheets later on, I’ll know what colors to order.
I’ve done traditional photography and darkroom work, so filters are nothing new to me. I still have a collection of Cokin and Tiffin filters that I use occasionally (hey, not everything has to be Photoshop!) but they won’t fit my new lights without being cut down and I don’t want to ruin them. So, here are some photos of my lighting adventure.
Here is the LED lamp. There is a gap between the white bulb and the black lamp housing, which is a bit difficult to see in this photo. The bulb I want to cover with the filter is just over an inch and a half wide. You can see the blue and yellow plastic filters that came with the lamps in the background, and that black ring top right (also shown below) is what screws over the lamp to hold the filters in place.
And this is a close-up of the ring for the housing. I really only need to cover the opening with any new filter or gel that I use, although the lamp housing will accommodate something up to about 2 inches.
Here’s the yellow plastic filter that came with the lamps. It measures about 2 inches across so it’s wider than the opening in the housing ring. I cut one of the Roscolux samples out of the book (actually not the whole piece, but about three-quarters of it) and placed it over the yellow plastic filter to compare sizes. I marked where the gel was too large and cut off the corners (not shown) so it would fit the lamp housing.
Well, it’s close! The red Roscolux sample gel is narrower than the yellow plastic filter, and here’s what it looks like when the lamp housing is assembled with the gel in place. Although the red gel doesn’t entirely fill the space inside the ring, crucially, all of the LEDs are covered. When I tried the lamp, it worked wonders. The white photography tent lit up like some demonic Halloween world, blood red and spooky and very, very bright. And that was with only one colored lamp!
So, it’s possible for me to use my samples for some actual photography, although I’ll need a second sample book to cover both lamps. If I buy larger photo lights I will need to purchase entire gel sheets, but for now, this is fine for experiments. I have my lights, and my camera. But now, I just need a good subject …
