has anyone incorporated motorised spotlights into their display if so what type brand did you use and how are they controlled i imagine they are dmx controlled also what is a good not to break the bank device.
These are called DMX Yoke lights. Here in the USA, American DJ, Chauvet are the brands DJ's use often. As you move up in quality and capability, Martin Mac makes some great units.
Also here in the US, we have brokers that will take the stock from theatrical companies and sell them used. This is usually not a bad way to go since those fixtures are usually well taken care of. Someone I have used is a company called GearSource.
My Martin Mac 250's are awesome, but need special enclosures to keep the weather out. Any unit of this nature is going to require weatherproofing
I believe that Tom (BetGeorge) is just wired differently. And I mean that in a good way. He was really fun to have dinner with, and his class at the Christmas Expo was intense. Learned so much in 1 short hour!!!
in Oz these are often called moving head lights, and range in price from $100 ebay specials up to $20K plus professional versions.
A few things to consider.
1. in order to get that beam effect you will need both a high power /output light and some smoke/dust/water in the air for the light to bounce off. a lot of the cheap Chinese versions just do not have the power necessary. you would be looking at around a 575w discharge lamp to get that effect. A 10 or 90 w LED version won't do it. you may get a decent effect with a 250W lamp but once again you will need the dust.
