Lighting Review: Prism Reveal LED Wash Fixture
"Best Debuting Product" award at LDI's 2009 lighting trade show and an exciting entry into a fiercely competitive market
There are many LED fixtures on the market today from a variety of manufacturers. While they come in a wide range of quality, price, and features, most of the fixtures are not terribly different from each other. When a new LED fixture comes along I am always a bit skeptical as to how "new and different" it really is. Then along comes the Reveal CW wash light, which, because of its differences, won the "Best Debuting Product" award at the 2009 LDI lighting trade show.
Physical Traits
The first thing that you notice about the Reveal CW is that it has a body shape similar to a Century ellipsoidal unit, kind of an elongated rectangle with somewhat rounded edges. The back end of the fixture is outfitted with a fan and heat sink while the front of the unit has a rubber gasket that holds in a plastic beam-shaping lens. The bottom of the unit has rubber feet to set the unit on, while the top has the switches for setting the DMX address, operating mode, and the power input. One side of the unit has the DMX input and output as well as a clutch knob for tightening the yoke while the other side has just the clutch.
Setup
Fixture set-up is straightforward. After unpacking, you will need to add a connector of the appropriate type to the supplied power cable, add a hanging clamp, and connect it to a control console via the five-pin XLR DMX input.
The Reveal CW powers easily with a Neutrik Powercon input and output connections. The power connections are positive locking and power can be daisy-chained to eight fixtures on one 20 amp 110 volt circuit. This is a great feature considering that this fixture pulls so little power at 180 watts and the Powercon connector eliminates having to deal with the connection issues IEC cables create with loose or unconnected cables. Add to this the auto-ranging power supply allowing the Reveal CW to run on a wide range of voltages without having to change any internal wiring, and you have a fixture that can be powered in any typical lighting rig.
DMX addressing is set from the LCD display and switches on the top of the unit. You set your starting DMX address for the unit just like any other DMX device. The number of DMX channels used will depend on which mode that you are using the Reveal CW in.
Operating Modes
The Reveal CW has four primary control modes. They are Correlated Color Temperature (CCT), X/Y Coordinate, Red Green Blue (RGB), and Hue Saturation Intensity (HSI) modes. These four primary modes also have several variations each that add control options.
In addition to deciding which control mode you want to operate the fixture in, each mode offers four different color algorithms that affect how the colors mix. These algorithms allow for subtle theatrical-type color mixing, bolder "rock and roll" colors, a balance between theater and rock, and a 16-bit resolution that gives you very precise extended control of the fixture.
