Florescent lights and flickering
Posted 08 September 2006 - 09:11 AM
I am looking to build a small eye light unit that I will place on camera (Arri SR2). Due to budget constraint?s I am looking at using your regular mini house hold florescent tube and fitting rather then the more expensive kino. I am told by many people that you will get flickering problems. Is this so, and if so how noticeable will it be in a eye light on a facial CU for example?
If there is anyone who has tested this could you please let me know what your result where?

So don't do it for an eye light. You would be asking for random trouble. What you could do instead is buy a simple clamp lamp with a silver reflector. You can find this in a hardware store. Then put some heavy white diffusion like 216 on the face of it. Also put on a small hand dimmer (you can get that at the hardware store too). Adding some 1/4 or 1/2 CTB is a good idea becaue you would almost always be dimming the light very low which would effectively add too much orange to the light output. The bulb itself should be a photo flood bulb. But a standard 100 watt bulb will work fine. What you get is a nice round light wieght controllable eye light that will cost you about twenty US dollars.
BTW you should post these type questions in the Lighting forum

For a green screen heavy feature I shot I built all the fluros out of leftovers from a rubbish skip? I do this job for the glamour
I upgraded the ballast and spent an afternoon testing the fluros for color. It gave me 6 good lights from about 20. I also got my brother who is an electrician to check my wiring. It was very cost effective.

The table overhead lights were R20 tight spots so it fell off the table pretty hard. I put black wrap on the opposite sides of the overhead fixture to kill most of the spill from the translucent lamp shades and the limbo effect worked out fairly well for such a tight area. The Dinette area is only about 10' x 10'. You can watch the short here:
