Trouble with flicker on DMX LED lights

Hi, welcome to the forums. My guess is the fixtures you have have a low quality LED driver with low refresh rates, so you need something that has a higher refresh rate. I would have you look at grabbing just one of these to test with: https://www.eliminatorlighting.com/mini-par-rgbw-led 
They are pretty affordable at 29 bucks MAP price each. they have a really nice white and they do color mix with RGB, you'll get more of a tighter wash coverage instead of a flat field "spot like" coverage with these, but they are a good  price to test with. 
Also we have not heard of anyone telling us these Mini pars flicker on videos. 
Here are a few example of them on the Eliminator booth at various tradeshows (Eliminator is a sister brand  to ADJ for the low-to mid level budget, but STILL  quality)

There is actually one running inside of a white scrim table throughout this whole video.... but the rest are in the center of the triangle truss in that video.

This video they are on the truss going vertically up and down on the back, you'll see them as you can see the individual red green and blue leds and the white. But they color mix in the air just fine.  

Does this help, do you need me to point you to a dealer for you to purchase them? We don't sell on Ebay.  

Yes, that does help a lot That price point is fine, although they say they are $39.00 each, not $29.00 when I open the link. That's still a good price however. Do I understand they the individual LEDs are not tri-color, you just have several Red, Green, Blue, and White LEDs in the same case? How far away does the light need to be from it's subject in order to get an even color mix? I assume the closer you get the more you would see individual colors brighter in some areas. Also, I always thought that to get white, you just turn up R,G, and B at the same time to the same intensity. That's how the ones I use now work. No matter, as long as they produce enough lumens to be 15 or 20 feet away, they will be fine.

As seen in my video, I do need there not to be much bleed over from one skeleton to the next. If I want to light just one, I need to be able to do that so that it's noticeable that only that one is being singled out, so I do need more of a spotlight than a floodlight.

I will probably purchase one soon to check it out regardless.

The light that you saw flickering in the first video is a tighter focused spot with a sharp circle, which is the exact effect I want for the extra head that gets lifted up. I use 2, one shining in from each side. Those were the first link for a light that I posted. I was only using white for that spot in this video, but it would need to be able to do colors as well. Do you have anything like that light? Until one that I have breaks down, those are the only two lights I currently have that I have flicker trouble with. Your link gives me a decent replacement for when one of the other lights die, but I still also need to replace those highly focused pin spotlights, similar to something that would be aimed at a mirrorball, maybe a little bigger area. The ones I have throw a fairly small circle even at 20 feet, which is what I want for that spotlight.

Thanks again!

I may have answered my own question. I went to the main website and found this.

It looks just like the ones I use, but it seems to be only white, not color-changing. That would be a problem.

Hi, look at the pinspots that ADJ offers, but they will go up in price, but for the ADJ stuff you'll not see any pricing on there, just ADJ points, and for the points, subtract one point and that gives you the advertised price, but you'll pay less if you purchase through a dealer. 
Look at these options:

The Pinpoint GOs are good, but battery powered, also the Saber spots are good options as well and come with a variety of lens options too...

Thank you so much for all the info. It's a little more than I wanted to spend since I already have a working system (to the naked eye) that looks really good using $15 to $25 fixtures, but I think it's worth it not to have the distracting issues in the videos. It was surprisingly difficult to find anyone who knew what lights to look for and the people who sell most of the lower priced fixtures have no idea what I was talking about and apparently could not be bothered to test their own products to see.

I appreciate your insight and knowledge, and as soon as I'm sure that I will still be getting paychecks, I will be purchasing some of the items you presented here.

I like the eliminator series, and I'm trying to decide between the Saber Spot RGBW and the Pinspot LED Quad DMX, both from ADJ. I already know the quality of ADJ products since I was a mobile DJ for 25 years and used many products from ADJ, but I got out of that business in 2005, so I never really got into the LED lighting or DMX during that time.
