OK, this might sound a little
bit harsh, but really I am going to say this entirely for your own good. To quote a show I worked on earlier this year, harsh isn't always true but it usually is! Having read this thread and your others, here's my advice:
In the real world, this title has absolutely no relevance. You may run the crew and design shows - all
power to you for doing that - but when it comes to buying equipment, the school is not going to give you $15,000 and say "here you go, go buy what you want with it." It just does not work that way; there will be procedures that have to be gone through - multiple quotes for equipment, for instance, red tape that has to be worked through and a senior staff member is going to have to sign everything off. If you walk into a professional
theatre looking for a job and tell them you were the "director of lighting and sound" they'll laugh at you.
Wrong. You need to learn how to use the equipment you have properly first. While
LED technology has come a long way in recent years, in terms of brightness they're still nowhere near as bright as a regular
parcan; buy them to use for colour washes and you'll probably find that you have to turn all the other lights off to see the colours anyway. You would be far, far better to buy some decent fresnels and a good
stock of
gel which will give you much, much more bang for your buck. As for the moving heads, DJ heads will be the same as your existing coloured lights - you'll have to
switch everything else off to see the effects. I work in a 300-seat professional theatre which is a pretty small space; we do six shows a week, 44 weeks of the year (we do eight plays a year, with a week-long production week for each show) plus a kids show during the daytimes for two weeks every school holidays (3 shows a day), and an improvised late-night comedy show every Friday and Saturday night. So we're doing upwards of 450 shows every year, and do we own moving lights? No. We rent them when we need them - which is not for every show. That way we get the right light for the application; if they break down the hire company gets us a replacement in double-quick time - currently we have a pair of
Martin MX-10s in the rig; both have broken down over the last week, and the hire company has been down with a replacement for us within half an hour, and earlier this year we had a Mac600 power supply blow up and catch fire, and again we had a replacement within half an hour; and the biggest thing, we don't have to pay for the upkeep and lamp replacement of them. Had we owned those units, we would not have had the parts in stock to replace the broken parts (both the MX-10s had busted stepper motors) and our shows would have been seriously compromised because of it. Don't get
me wrong, I'm not saying that NOBODY should own moving lights, because that would be stupid, but until you have the ongoing resources to maintain them, and the real, genuine need for them, rather than the motive of wanting toys to
play with. Also, DJ gear is of a lesser quality as a general rule; you'll find things like they won't hold their position properly - each time you go back to the
cue where it's in a certain position, it may not be in exactly the same place as you plotted them - and gobos won't index properly so it'll never be the same twice running. You've been given some excellent advice in this thread from people who really do know what they're talking about; you made a good decision in coming here to ask for advice, now take the advice you've been given!
Like I said, I'm sorry if this sounds harsh, but you're, what, 17? There are people on this board who have been working in the industry since before you were born - listen to what they have to say!
