Through various circumstances he ended up with a major league education on how fluorescent tubes are made, how higher CRI’s are achieved, why it is harder to make higher CRI bulbs, etc. At the end of the process Richard had the tube manufacturer very interested in supporting him in offering a “just under 90” CRI, reasonably priced bulb to compete with the likes of the Studio grade bulbs from Osram or General Electric. Just remember this practical advice about CRI. Richard completed several video projects using fluorescent biax and CFL’s that were CRI 80 (color temperature 3500K was his favorite and was more readily available than 3200K anyway) and he never once saw a green tint to any of the video or any other artifacts that he thought were unacceptable. These “green” artifacts usually only show up in film and not video so if you are primarily doing video work (and not film) then you will probably never have to worry about it as long as you use appropriate color temperatures in the range of 3000 – 3500K or 5000 – 5600K.

This is our 5600K color temperature PL Biax bulb. The test report, is for the most part, self-explanatory. It is run using an Integrating Sphere (see our Article on Color Temperature and Color Rendering Index). As would be expected, 2 or 3 bulbs are usually chosen at random for testing from a batch produced by a factory. You can find our 3200K test results here.
