I have 2 of these cracking lights they are produced in the USA by FloLight and are 5600K daylight balanced. I have seen them advertised by Prompterpeople.co.uk in the UK and now come in 500W (£399) and 1000W (£699) flavors.
These lights are well built, sturdy and heat free. Remember the burnt fingers using the old Red Heads, a thing of the past and the best news is the ability to add velcro to the back of the barn doors and velcro your scrim or colour filters…NO HEAT.
Another nice feature is the ability to dim the lighting from 100% to 25%. I tend to bounce the lights if I have a white ceiling giving a smashing 5600K diffusion with no shadows. One further feature is the 4 pin 12v XLR allowing you to run these lights on 12v batteries, great for outdoor work. A word of caution I find these lights very harsh if used direct with no scrim if filming an interviewee, in fact I will go as far as to warn you not to use these lights direct into someone’s face without diffusion.
