The Problem that i am facing is for our biggest production i am running out of power
. I need to power
40 1000w Pars, 4 Cyberlights CX, and 20 LCD
lights. If i have done me math right i am about 58 Amps short of having enough to power
everything. Note that the Cyberlights run on 208
I haven't done the math but I take it you worked it out on everything being on full at the same time?
I have been in the same boat but so long as you tell the students never to bring every light up to full you should be able to get a away with it.
For example unless you are using all Par
64's with just one colour then generally they shouldn't be on full all the time.
It is just a matter of balancing the load if the power
supply have current
meters then it is easier. But even if you don't and you can find out what circuit
supplies which dimmers you can spread the load across the different packs. It sounds like you might have this info already but if not talk to the schools electrical contractor.
Failing this if the circuit
breakers are at least labelled for lighting by turning turning them off one at time you can get an idea of which controls which dimmer
. I take it from your plug
diagram that each dimmer
has 3 channels per 120v leg
that comes in from the plug
. Someone who has used these packs may correct me. If you have to do the circuit breaker
test make sure the dimmers are only lightly loaded.
The inital patch up takes a while but since you have a DMX
board you can then softpatch
the lights into a more sensible order for plotting.
Another thing to think about is using PAR
64's the best thing for the show or should you hire in other lights such as more leko
's. My question only really applies if you are using some of the PAR
64's as area lighting as opposed to just using them for colour washes. Because as you know you can get lower wattage lights that are better for the area lighting then the Par
64's which help cut your power
How far off is the schools new theatre
? If it is within the next year or so and the lighting rig hasn't been set set in stone you might like to contact some local suppliers. Ask them if they can provide a few lights from their range so you can do real life comparisons. They may say no but it can't to hurt to ask. You could sweeten the deal by a free add in the program. If they come to the party you might also be able to invite other teachers/technicians from local schools for a showcase of their product. Obviously you'll have to get your school's permission. I have done a school show where a lighting manufacturer's products made the difference between having enough lights and not enough. They also threw in the loan of one of the follow spot's they made. This was dealing direct with the actual lighting manufacturer as opposed to one of their suppliers.
My idea might be more trouble then it's worth.
