Schulz 7000 lumen video light?

Hy,

I would like to buy Schulz GSW80 video light I saw on Dusseldorf boot.On test I compared it with new Mangrove 8000 lumen light had, and Schulz produces very impressive light. They had 2 versions of video reflector 7020 lumen warm light , and 9000 lumen cold light! I never shoot with cold light! Does anyone know what is the difference when shooting with cold light vs. warm light?

Thank you

I would imagine they mean that the colour temp would be high 6000k (white) as opposed to sub 5000k which is more orange.
