Here is the description I found:
ISIS 575: This bright 575W
unit has 12-18
DMX channels. It has a two-direction rotating
prism. It provides eight pure colors and eight mixed colors through five steel color gobos plus one white with adjustable positioning. One glass
gobo has adjustable speed. It also has a 1-10 mechanical linear
dimmer and high-speed
strobe. The 540° pan and 250° tilt have a very accurate micro-adjustment (spot and
wash versions). Its
base protects against overheating and high
voltage.
I have not worked with this
fixture but my impression is that it is more suitable for
stage use than
house parties. It has a 575
watt arc lamp, which is bright but means the
fixture will be bigger and heavier than a
LED mover. It will also lack the color-changing abilities. While the price looks good, these are older fixtures and have aging electronic ballasts. I think it would be better to look for a
LED mover that is intended for DJ use. There seems to be many on the market but maybe not at $45.
