I was curious why daylight and tungsten was easier to deal with, especially for skin tones. Looking at the spectral distribution of light, tungsten and real daylight provide a continuous spectrum of light, while fluorescent/CFL produce highly spiked light- not continuous. The good news is that the latest LED lights come very close to tungsten/daylight for continuous spectral light. I've got some low-cost CFLs in 2x3 and 2x2 light rigs: I'm going to replace the CFLs with LED bulbs at around 5000K (probably Cree- thanks for the tip FilmMan!) to match the other ~5000K LED lights I use (currently Z96, YN300, YN600, and F&V R-300). An LED spot in a clamp-on work light will also be handy. http://www.cs.cmu.edu/~zhuxj/astro/html/spectrometer.html http://www.popularmechanics.com/technology/gadgets/tests/incandescent-vs-compact-fluorescent-vs-led-ultimate-light-bulb-test#slide-1 (see the spectral charts) (CFL can work OK, but I had to use a tuned camera color profile and make sure WB was set carefully, otherwise trying to fix in post was time consuming).

Cheap CFL bulbs are convenient, efficient and economical - but they typically have a lower Colour rendering index compared to Tungsten based lights and other more expensive lighting systems. Just how much of a difference is there? You decide (additional images/stills on my website: http://www.tommajerski.com/critest.html ) Shot on the BMCC 2.5k in Raw mode. Samyang 35mm 1.4 lens with no ND or filters. White balanced perfectly before the same colour grade was applied in Davinci Resolve 10. Debayered to UHD for better youtube viewing quality. For best results, set it to 4k quality and video on a HD monitor. White balanced exactly to the same point before applying a simple Contrast + Saturation grade.
