Thanks for your response! For filming purposes, ideally the light should be 5600K and as high CRI as possible. Shots filmed with a 65 CRI light are going to miss quite a bit of spectrum and will look dull, but 3000K color temperature is going to be too yellow as well.
There are some LEDs with 95-98 CRI, but it looks like integrating them would require quite a bit of re-engineering, as their dimensions and specs differ: https://www.yujiintl.com/high-cri-led-lighting
I see that Cree has a 5700K 90 CRI LED available - XHP-70.2 - that seems identical to MK-R in size and spec, at least at first glance, except they’re higher powered (29W / 4000lm): https://www.cree.com/led-components/products/xlamp-leds-arrays/xlamp-xhp70-2
Do you think it might be feasible to build several Lumen Lights with these? Ideally we’d like to install 14000-20000 lumens on BlueROV, so depending on max output, it would need between 4 and 8 lights in 2 or 4 groups.
