[chris pike]"From my experience, I would argue that bicolored LEDs are not a good use of money. You are better of buying a daylight LED and throwing a CTO gel on it. What is your opinion?
You will get more power with daylight LED + gel than with a bicolored LED adjusted to match."
With incandescent & HMI lights, sure. With LED's, no. A "warm" (i.e. 3200K) LED is manufactured to already be emmiting at that spectrum so you're getting more output that way rather than "throwing away" light by gelling a 5500 LED source. The color temps in between are often just a blending of the two outputs.
Also, I don't like working with the knobs on the bicolored LEDs, they are difficult to properly adjust."
Pretty much agree there and that's largely going to be up to the manufactures design.
