Hi all,

I just finished installing some architectural lighting for a client (a church) that has a nice, tungsten look. In contrast, the intelligent spotlights they've used for their stage for several years (Chauvet Q-Spot 560) are stark, cold white. Have you ever used gel paper (thinking 1/4 or 1/2 CTO) on a light that wasn't designed with a gel frame? I'm wondering if it's worth taking one of these movers apart to see if there's a place I could put a gel sheet.

Ideas:
-Attach gel on the outside of the lights
-Take the lights apart and put a gel sheet inside of the lens
-Modify the color wheel by putting different shades of "color correction" gel sheets in?

Does anyone have any experience with this?

Thanks,
Andrew

Hi Andrew, the correct solution in this situation is to use a glass gobo of appropriate color since this fixture doesn't have replaceable colors.  You don't need to make a pattern on the gobo - just a circle with the correct color made to the appropriate size/thickness will work.  While cheap and simple, putting gels into the light can interfere with moving parts and cause problems - especially if the gel melts or burns.  Hope this helps!

in addition to these good points, you may need to experiment with the color, as a generic CTO filter may not end up where you want it depending on the color content of the light source.

Jeff, that totally makes sense. I opened one of these lights up and found that one of the two gobo wheels has removable gobos, so I guess it's time to call a custom gobo maker. Got a favorite?

TJ, thanks. It sounds like it will be best to order a variety of correction gels to find out exactly which color works best with the light, then get a some glass gobos made.

Thanks for the replies, guys!

For converting LED sources, Lee Zircon Warm Amber series are my go to line. Especially the Warm Amber 2 for converting white LED's to a tungsten look. It's almost perfect.

I like the idea of using a gobo to do this opposed to outside mounting as the filter does affect the colors, some more so than others.

That's a good point. We don't typically use the color wheel for anything, but it would be nice to keep the colors unaffected, just in case.

You could replace several of the gobos with different # filters to have some variability.

I don't have any favorites in particular, but something like this will probably work.  As mentioned though, which exact color to get might involve some guesswork.  While these aren't inexpensive, it's the most correct way to solve the problem and should last the life of the fixture.

Unfortunately your fixture doesn't appear to have replaceable colors, so this would involve destruction of the existing color wheel and cementing a new color into place.  Since you have 2 gobo wheels I'd go the gobo route understanding that you'd be giving up the ability to overlay CTO on a rotating gobo...all of the other functionality remains in place.  Hope this helps!

Haven't used them in several years, but these used to be our source:  https://us.rosco.com/en

Maybe not destruction, the white color will be just an open cutout. Cementing a dichroic CTO filter in that slot would do IF you never need a cold white. I'm sure a supplier could cut the glass to the right shape and recommend/provide an adhesive. A scan of the color wheel would provide them of the correct dimensions. This would keep all the other colors correct and wouldn't limit you from the gobo selection.

One of the gobo wheels has replaceable gobos.  remove the patterned ones and replace them with filtered.
You don't have to modify the color wheel.

When I first read the thread title, i was wondering what the goo was that was leaking out of the hot mover.

Ha! Gives a whole new meaning to warm white gel.

Gobos are on order! I’m going to try 1/8 CTO first and see how it goes. Thanks for the help, everyone. I’ve never really used gobos except for occasionally messing with the built-in gobos on different movers, so I wouldn’t have even thought to look for glass filter gobos.

[Andrew Henderson]

Forgot to post a follow-up after receiving the gobos! We’ve had great success with the CTO gobos we ordered from Gobosource. We ended up installing 4 gobos in each light: 1/8 CTO, 1/4 CTO, 1/2 CTO, and 1/1 CTO. It’s been really nice having the options, depending on what we’re doing! We tend to go with 1/4 to 1/2 during live music or dramatic events, and 1/8 to 1/4 for preaching/speaking. It tends to depend on the ambient light in the room and the intended ”vibe” of the room. Having the color correction options has really allowed us to improve the presentation without upgrading fixtures.
