I'm pretty sure I know the answer but can I use normal florescent light bulbs in a kino fixture? Are there any cheaper bulb alternatives other than the proprietary ones? Apart from color temp, why not use normal daylight balanced florescent bulbs?

A woman that runs a lighting store near here offered to sell us 2 foot bulbs "close to daylight" for $115 a pop. the price to me sounds close to kino bulbs.

Thoughts?

As for the bulb cost, I'm glad you posted here first. If I'm reading this correctly, the store wants $115 per tube?! Kino safety coated 2' daylight tubes are $22 a piece. Otherwise, $130 for a 6 pack of tubes.If the price is for a 6 pack , that might be reasonable.

Technically, no matter what tube you buy you're looking for two things in the tubes: color temperature and the associated Color Rendering Index. Adrian Sierkowski has a great explanation of CRI in this thread: http://www.cinematog...=1 Kino tubes have a high CRI, color accuracy and wavelength. The closest match would be the GE cinema plus tubes, which I think actually come in at a higher price than the kino tubes.

That combined with the price and safety coating more suitable for film environments make the kino tubes a good combination for the fixtures.
Hope this helps.

Thanks for reaffirming what I thought I knew. I had a producer ask me for her friend who owns the lighting store. I gently told her that we were just fine in our set up and that the bulbs were "special film grade bulbs". $125 per...I'm not sure why anyone would have thought we needed that but hey, thanks for the replies guys.
