Thanks everyone on the suggestions for the Graflok back. ... anti flicker "special" flourescent tubes I do not know for certain but I would bet if you had a dual power supply to the lamps you could stop the flicker. Flickering is caused as the current changes direction inside the tubes. You need AC power to strike the arc but once it is going DC would do the trick. As a suggestion get 300V caps and feed them rectified AC ( pulsating DC ) from the power line with a diode ( 1 KV rating might be required) in series with the output of these caps connect them in parallel to the same AC connections to your lamps. By having a switch for the AC side and DC side, once the bulbs were lit off you could switch off the AC power stopping most or all the flickering. Caps for this might be cheapest from someone who supplies them for motor starting. Using 'AC" caps vs DC would be an OK substitution and keep things from getting exciting if the DC caps were installed backwards. Keep everything "unplugged" until you are finished wiring everything. Of course if you REALLY wired things wrong there are circuit breakers. Also, for real, this could lead to a dangerous situation where, if things were wired incorrectly, you could place the "wrong " side of the AC line to the fixtures. So make sure they ( the fixtures) are grounded and find a GFI plug for your first test. If you have no idea of what I am talking about do nothing. Or find an electrical or electronic engineer friend to figure things out . _______________________________________________ Cameramakers mailing list [EMAIL PROTECTED] http://rmp.opusis.com/mailman/listinfo/cameramakers
