Lighting in London
Posted 10 June 2008 - 11:29 PM
I have a few videos coming up in London and I've never worked with lighting equipment that is 240v.
Do you still work with 15/20 AMP circuits?
Does that mean you can hold a 4000w on one 20amp?
Does anything change when working with Tungsten Lamps? Kinos? HMIs?
PS: I'll probably re-orient myself once I hit the rental houses

Industrial premises, including sound stages, will differ, but generally use Ceeform connectors where blue is single phase and red is three phase in 16, 32, 63 or 128 amp capacities. Presence of a connector rated to a given capacity probably doesn't indicate that capacity is actually available. Bigger stuff than that will be on camloks but you will presumably hire a local electrician before you go anywhere near that sort of thing.
This does create the happy circumstance whereby a household circuit should be able to supply 3120W and you certainly can run 2.5KW HMIs or a redhead-blonde combination in people's houses without problems. Electric kettles and space heaters are usually 3KW here so circuits are built to stand it.
Flicker on discharge lighting, including fluorescents and HMIs where they use iron ballasts, and local TVs, will be at 50Hz. I don't know what the safe shutter angles for 24 or 23.976fps are.

Hopefully I'll have a gaffer/spark to just keep me in check, in case I switch back to the land of 15AMP/120V/60Hz thinking.
I've ordered mostly smaller units with a 2.5k Par, 2k OpenFace and a Image80 being the largest.
