About the ETC Irideon AR500 Exterior Wash Luminaire
The ETC Irideon AR500 Exterior Wash Luminaire is a computer-controlled outdoor floodlight built for wet-location use and carrying national and international safety listings. Its radial colour changer uses three sets of permanent dichroic filters, blue, amber and magenta, to produce smooth crossfades through the full visible colour spectrum. Beam control is provided by either a diffuser mechanism, which gives precise and dynamic control of beam distribution, or a douser mechanism for full-field dimming of beam intensity. The AR500 supports the Irideon Composer control system as well as standard DMX-512 control, where each luminaire requires four DMX channels: three for the colour filter assemblies and one for the diffuser or douser.
ETC Irideon AR500 Exterior Wash Luminaire — buyer FAQs
What is the ETC Irideon AR500 Exterior Wash Luminaire and what is it used for?
The ETC Irideon AR500 is a computer-controlled outdoor floodlight designed for permanent wet-location installations. It uses a patented dichroic colour-changing assembly to project smooth crossfades across the full visible colour spectrum, making it suited to architectural and exterior wash applications. It carries national and international safety listings confirming its suitability for exposed outdoor environments.
How does the AR500's colour system work?
The AR500 uses a radial colour changer with three sets of permanent dichroic filters in blue, amber and magenta. Each dichroic filter is a rotating piece of coated glass that passes only a limited portion of the light spectrum. By combining these three filter assemblies, the luminaire can produce smooth crossfades through the entire visible colour range without gel changes or manual intervention.
What control options does the ETC Irideon AR500 support?
The AR500 supports two control approaches. It can be operated via the Irideon Composer control system, which may run on a PC alone, a PC with a Master Control Processor, or a PC, Master Control Processor and Remote stations. It also accepts standard DMX-512 control using a DMX Interpreter and a programmable lighting controller, requiring four DMX-512 channels per luminaire: three for colour and one for the diffuser or douser.
What is the difference between the diffuser and douser options on the AR500?
The AR500 offers beam control through one of two mechanisms. The diffuser provides precise, dynamic control over beam distribution, allowing the spread of light to be adjusted. The douser provides full-field dimming of beam intensity, fading the output across the whole beam rather than shaping it. Each unit is fitted with one or the other, and the dedicated DMX channel controls whichever mechanism is installed.
Who makes the Irideon AR500 and where does it fit in the ETC range?
The Irideon AR500 is made by Electronic Theatre Controls (ETC), an American lighting manufacturer known for control consoles, dimming systems and fixtures used across theatre, architectural and live-event applications. The AR500 sits within ETC's exterior luminaire offering, specifically addressing permanent outdoor colour-wash installations where wet-location ratings and automated colour changing are required.
