Charles DeRosa Posted March 3, 2006 Share Posted March 3, 2006 What are people's thoughts and experiences putting kino bulbs in normal fluorescent fixtures, especially if mixing it with other lights. Because the kino ballast overcranks the bulb and a normal fixtures doesn't I'm afraid to trust the color. It looks off to the eye (which of course isn't particularly trustworthy). Also, what kind of drop in output have you found? Down about 30% I'd guess. Thanks, Chuck DeRosa Los Angeles Link to comment Share on other sites More sharing options...

May I suggest two Macbeth Color Checkers in a 45-degree "V" arrangement, with one side of the V lit by the Kinoflo unit, and the other by the regular fluorescent? So you get a side-by-side comparison of color rendition and tone scale. Link to comment Share on other sites More sharing options...

Premium Member David Mullen ASC Posted March 3, 2006 Premium Member Share Posted March 3, 2006 I put Kino bulbs all the time in ordinary fixtures on location. I haven't noticed a visible shift in color. Anyway, when talking about color accuracy, compared to what other tube you could put into the fixture? A Kino 55 tube in an overhead fixture is still going to have a higher CRI value than a Chroma 50, Vitalite, or worse yet, a Cool White. Link to comment Share on other sites More sharing options...
Premium Member Phil Rhodes Posted March 3, 2006 Premium Member Share Posted March 3, 2006 Hi, It's entirely possible to change the colour of a tube by driving it differently. Overdriven they go purple, underdriven they go yellow. This could very adversely effect the CRI. Phil Link to comment Share on other sites More sharing options...
