The good folks over at EVSOnline gives you a peek at Cineroid's L2C-3K LED Video light. Instead of providing two different LEDs which normally cuts your output in half, they decided to provide options for swapping out ALL of the LEDs. Of course this means you can't dial in mixed temperatures. It definitely looks like a good light, but if you want the variable temp options, be ready to throw down over $500 bucks. Three different packages, available via B&H (click here).
