Hey,
so part 2 now the Light:
Generell Light is like the sound, you can choose thousands of different products.
Some generall aspects:
I often hear from the older generation when they book me if I have some classic lights. Classic lights are for them the PAR-56 or PAR-64 Spots with 300W or 500W lamps and color filters in front of it. This is a real classic set to have some of them but with 500W PAR-lamps is not modern today. They are to warm and broken after 150hours of running (sometimes less

) and you have to wait after the show up to the point the lamps are not as hot that you can put them away.
So if you need the classic light and I also have them I prefere to the classic version but with the modern LED technology.
For smal areas it is enough to have 4 of them. (in the past I run with 4x 56Par and a very heavy dimmerpack and now I have a Bar with 4 LED Cans and it is very slim and the light is brilliant.)
These classic light is very basic and with the modern technology DMX and LED you can run thousands of different shows and create effects like can-can or Strobe.
For parties with the of recent date people like 18 to 30 they want more than these classic lights. For those you can use effects.
Effects can be the expensive ones and the cheaper variants.
For me for example I have both. Its easier to create a nice setup of light with a range of different effects and devices.
Some classic devices are the Moonflower or the Zig-Zag (both aviable from Eurolight which are cheap and good quality). These are effects which are beam different ligh rays in different colors through the room and they are rotating with the BASS
These are the cheapes ones and aviable for round 50 to 100 (also now aviable with LED and DMX interface so you can now manage how it rotates and so on really nice but I currently not ordered some of them but I saw them at the local store)
The expensive version is to buy Scanners or movingheads. With like two scanners you can create nice Effects and with combination of fog you have a very nice light show. They are also controllable with DMX. Scanners are also now aviable with LED technology but I have currently not tested how good they are. I had for my last gig a movinghead from Showtec (Showtec Indigo 4500) this is a very nice device. Small and powerfull (light and equipment of the system).
Generall with scanners and movingheads they have different equipment (colors, gobos, Gobo rotation, prisma, dmx focus and so on) here you get often that what you pay so if you want a system with all the functions you will pay much but you will have a nice system to create effects.
So I told that most of the equipment of light is now aviable with DMX. DMX is not as modern as some peaple thought but it is nice and easy to use.
You have classic 512DMX channels. Every device with DMX has a number of channels like a Scanner or movinghead 6 - 16 channels. You set on every device the start-adress. This start-adress is for the device the information on which channel it will wait for your information. Like start-Adress 0 and the device has 4 channels (LED PAR): you have then blocked 4 channels. The next device can run at channel 5 and so on.
You can also set more devices to the same channel so they are all doing the same. With much LEDs or Movingheads or Scanners you create with that nice effects.
All in all it depends on what you want to do with the light. Is it only for classic lightning the dancefloor with the classic lights you will only need the PARs (4 to 8 depends on the size of the area, for very big areas more

).
For more light (ordering me you can choose Light/Light+ Packages and so on) Use Effects (set to the center) and Scanners or movingheads (at the end of the floors to get a big range of movement of the scanners).
What I not named up to now was where you want to setup the light. For that you need stands or Truss. Truss is the very expensive but looking nice variant

. And stands is the cheaper and most flexible variant.
I will look to my photos and upload some and post them hear to give you some pictures about what I mean. The party stands and falls with the light and also sound but most the light.

Christian
