This is the type used in night clubs, and is also used by mobile DJ’s and bars that are open late in the night. One of those types are called scanners and they use mirrors for reflecting beams which retate around giving a twister effect by projecting many beams at once. Another is the strobe type, these simply have an intensed flashing to them. These kind can be controlled using a sound activation that is internal, and a the sound has been built into the systems functioning unit. There are some more control options such as the master slave or daisy chain, and the DMX control. The following are the four different types of this kind of lighting, they are the: Retro; Lasers; Projectors; and Party lights.
Back in the beginning of the disco days, colorful disco balls were the main kinds used for disco. These appeared as mirrorballs, and gave out a multitude of colors (par 16 lamps).
The lasers are fairly new to the DJ’s. It contains laser diode and consists of using an array of mirrors in which to get the multitudes of colors projected and the many beams it gives off.
The 1980’s and 1990’s seen a whole new type of DJ lighting begin to evolve due to the improving technology of the halogen lamps. This type is projected by also using mirrors, as it shines onto the mirror through the use of a sheet of filtered gel it created colors, this could also be used with a ‘gobo wheel’ in order to create different shapes. Today however, many of the projector DJ’s lamps are being replaced by LED technology instead.
All the party and disco types of DJ equipment is considered by the industry which designs them to be sold for use in the home and thought to be for disco partying, including DJ’s.
Here are a few interesting facts: The halogen buld will give out a life span of approxiamately 2,000 hours, but an LED can give anywhere from 50,000 to 100,000 lifetime hours. This clearly shows that the LRD is going to use less power than what the halogen bulb does. Did you know that a halogen bulb is 250 watts, compared to 16 watts from a light emitting diode? That means that it is going to draw less power from the wall outlet and use less energy. Using them are a lot safer and less of a fire hazard, because a halogen bulb gets very, very hot. Speaking of getting hot, ddancers work up enough seat on their on and the last thing they need is the heat off of a halogen bulb shining down on them. With the halogen fixture a separate bulb would be needed for each color wanted, where the LED will give all the colors wanted with just the one, and then some. Just pointing out some of the advantges of the led bulbs in comparison to the halogens.
