LED lighting for stage and theatrical has never been too cheap. It seem like every major stage lighting manufacturer has dived into the LED lighting fixture market while cheap imported lights mean that even a small band or DJ can get a slice of the RGB colour mixing action.
Why Buy LED Stage Lights?
High Powered LED technology means that we can now use those funny little glowing things that used to live on the front of your television, in theatre shows, live music gigs and corporate shows. LED fixtures have many advantages over “old fashioned” lanterns that make them attractive in stage lighting.
1. Low Power Consumption
Because the LED uses a fraction of the power of an normal lightbulb , the power consumption of LED lighting fixtures is very small, meaning you can use a lot of fixtures on small power supply such as a 13A domestic socket. This is great for small band lighting rigs and the disco/party DJ.
2. Low Heat Radiation
Although LED stage lighting does produce heat, the fixtures produce light without getting extremely hot. Modern stage lighting lamps produce more heat than they ever have and this has been coupled with improved lantern casings to minimise the risk of burning the operator. There are, however, some environments where the low heat properties of LED stage lighting are desirable.
3. Lightweight and Portable
The hardware that LED fixtures are packaged in does not need to be heavy and, although the various power supplies and elements all add weight, LED units are usually fairly light.
4. Colour Effects
The most common way for LED lights to be used for stage lighting purposes is using a combination of different coloured LEDs. A fixture with all three three lighting primary colours, RGB LEDs blended together in different combinations gives the lighting designer loads of colour choices. This is using a principle called Additive Colour Mixing, where the coloured LEDs mix on any surface that reflects the light.
5. Small and Compact
LED lighting fixtures can be made in small, discreet packages which suit applications where size and brightness are important such as exhibitions stands.
6. High Brightness
This really comes down to the ratio of light brightness to power consumption. The new high powered LEDs are very bright considering small amount of electrical power they use.
So, What Types of LED Lighting Fixture Might I Choose?
For the purposes of stage lighting, the RGB colour mixing capabilities of the LED fixtue is it’s selling point. The main forms are in a lighting batten, a long strip with an array of red, green and blue LEDs or in a compact array that produces a beam of light, similar to a conventional PAR can or a Floodlight. The batten are useful for lighting up flat areas, such as a wall or backcloth, while the PAR / Flood fixtures will give you a beam of light, similar to their conventional stage lighting relatives.
Moving Light technology has also joined the LED bandwagon, with LED arrays being packaged in all shapes and sizes of “waggly” LED Moving Head fixtures. Another stage and theatrical use for the LED is in a large, screen-like array which can be used to show colours, patterns and moving images like a low resolution television screen.
How Do I Control My LED Stage Lighting?
Stage lighting is usually controlled using the standard DMX512 protocol, and LED fixtures are no exception. Different DMX channels control the Red, Green, Blue while other channels may deal with overall instensity or special chases and effects. The LED lights are linked to the DMX signal chain in the same way as other intelligent stage lighting fixtures and do not require extra dimmers to control them.
If you don’t have a DMX lighting controller, many LED stage lighting units can be used in “standalone” mode or can have control locally, using a simple controller/power supply that enable you to change the colour and run simple effects.
