Hello all, and I appreciate everyone chiming in. Some update on my end.. I received a sample heatsink and am comparing my options. One of the heatsinks advertise compatible mounting holes for the MeanWell HBC series (a different driver than what I originally proposed). This is attractive to me...

I will start with the variable potentiometer with testing and report back. A potentiometer is certainly the most inexpensive option. The color spectrum specs are listed, and are within the tolerable ranges for high quality light. The main things to look out for are R9 values (skintones) and R12...

Yes, I do plan to test one prior to building all. Thank you for verifying the PFC and PWM setting. To Tom's point, wouldn't a simple analog potentiometer be a safer option? By using PWM, wouldn't it introduce a higher chance of there being flicker, due to the nature of its design? Concerning...

I apologize if I was vague, as I shouldn't have been. Up to 2,000FPS is fine to maintain flicker free operation, at any shutter. Another assumed characteristic of dimming that is required is little change in color-shift. Obviously, also, if one dimming technology is more efficient as far as...

Hi Hutchphd, My dimming requirements are to achieve smooth dimming without causing any flicker appear on camera. I can compromise a bit on the "smooth", and have it dim in "steps" if that's what needs to happen. But I cannot compromise the LEDs appearing as flickering when recording at High...

Hello, I am looking to build an LED Panel for a film/video application. I have a few specific requirements in mind. 1) Color Accuracy beyond general CRI ratings. 2) Flicker Free to Camera (What specifications in LED drivers should I be looking for to ensure this flicker free application?) 3)...
