Hey .. just my 2 bits but .. I have been using these..
http://www.skaeser.com/servlet/Categ...HTING:COOL-FLO for years ..
they are way much cheaper than KinoFlo lighting and for video and photo I have found HUGE success with them .. I have recommended them to everyone I know .. long and short you do get what you pay for .. they are not the same quality construction as the much more expensive Kino's but for the price and bulb costs .. they are awesome in my book ....
