I'm strickly talking single phase here, in the festival world 3 phase isn't generally something we do. While of course you can run the par cans off a 200AMP distro try adding any addtional rented and or upgraded fixtures (rented discharge lamp moving heads) or rented followspots and it will easily put you above a limits of a 200AMP distro. you'll want to have plenty of head room rented and or future gear, and with lighting that power gets used up - much much faster than audio. In audio a 14-50 50AMP single phase (50 on each leg) would be able to power a pretty decent sized concerts, not so much with lighting.
Hi again Jason;No argument here re: how additional loads mount up but I'd still like you to explain to me how your 32 - 1 Kw lamps require a 300 Amp service regardless of single or triple phase.Please show me your math that gets you there.Toodleoo!Ron Hebbard
So LED's are nice and all, but they don't have the same effect as a good PAR can, nor do LED's look as good as one to the front. So, what I'd like to do, is build a simple rig of PAR's (8-12 trees of 4 with a dimmer pack on each) with a 200A single phase distro to go with it. This way, I can either take just 2 trees on a small show on T-bars, or set them up with 4 on the front and either LED's or the other trees on the back, or any combination. Where would be the best place to start to purchase cheap (but decent) cans and figuring out the best way to wire everything up? Also, what would be the best size bulbs to use? Biggest stage these would see will probably be a 32 x 28 if that.(Also to note, at some times they will be used with LED's as well for color wash. And yes I do realize the irony that one of my older topics on lighting is pretty much directly below (or maybe even above) this one)
and it's not cheaper or better (IMO) anymore.
Re-read my last post.
Hi Jason;O.K., I've re-read your last post; again, please explain your math re: how 32 - 1 Kw. lamps require a 300 Amp service if single phase. I must be thick as I'm not seeing this.Toodleoo!Ron Hebbard
I have recently been watching the LED Light bulbs and have found that Home Depot and Lowes have been selling some Par38 Flood and Spot light bulbs for around $30. These bulbs are starting to have the temperature of 4000 k and 5000 k. making them equal or hotter than some of the halogens. With par38 cans it would be easy to use them and produce a smaller bar type rig for a show. You will not have the power draw of the 500 watt PAR 64 or the 1000 watt. The question left here is the lumens and the FC. I have been wanting to do this for small plays and the bar scenes. Still working on the budget of the small weekend budgets. Most of the bands are bar low budget and want the sound and will not pay for the addition of the lights. Then if they do have lights they focus to much on the frills and action and cause the artist to be in silhouette. Fixing this with a small set of par38's can help but getting a lighting tree out in front of the artist, stage, and speakers is a liability problem with wires and tree out in the crowd. On some of the small theater work I have done it is easier and safer to place the lighting and keeping the crowds away. I have a stage setter 8 with 4 DP415 dimmer packs to work with. Funding the 12 cans is easy because I have found Bulbs America on amazon sells 4 par 38 cans for $50. 150 for the 12 cans is small. Adding in the LED flood lights is $360. 2 Trees $100. So adding 600 to lighting for bands not paying extra for the lights is still above my budget. But adding the lighting would bring something to the table the other sound people do not bring. I also run some other PAR 56 LED DMX, Laser, and dance lighting on a DMX Operator controller for smarter lights. This would place my system with two universe for operation. Programed and chases on DMX operator. Manual control of the white lights for following the solo or leads on stage. As the LED lights move into the theater to provide the strong single output and the correct lumens with color temp, we should see a move to the new lights and using LED more. Can we do so without having to change our investment in the fixtures? With wireless tech added in and a good car battery powering a small 400 watt inverter placed under the light tree. help to remove the wires and trip hazards, yes done that and it helps in the crowd. Having a safety person to watch and ensure lighting is safe was used, preventing the stand from being knocked over.
