Units tend to be of two types - the light beam is modulated by a moving mirror with the luminaire stationary, or, the luminaire moves to create motion. A typical unit, usually powered either by a small discharge lamp or LED, is equipped with various functions including intensity, focus, iris, colour, gobo, rotating gobo, pan / tilt, speed control and reset.



“Moving head lighting fixtures play a big role when it comes to our lighting design approach. I feel its important that a lighting rig have variety; tools from which the operator can pick from to create different looks. Our hierarchy when selecting fixtures starts from top to bottom as follows: Spots; Wash; Beams; and Effects. If and whenever possible, we also go towards using hybrid fixtures. Having a rig designed in this way helps us prioritise how many fixtures of which kind we can allocate toward the project’s budget. I remember when all moving fixtures lamp sources used to be lamps. Now, with advancement in technology, we have options with LED-based light sources. LED light sources have helped solve so many issues that we faced in the past. No more are the days of ‘I forgot to lamp off the moving heads on Sunday at the club’. Next thing you know, you show up the venue and fixtures are not working properly because they overheated over the last few days. I look forward to more advancement from manufacturers that continue to push the envelope. Moving head fixtures will continue to get smaller, brighter and more reliable.”
