A Lustr+ LED variant is also available, offering energy-efficient output with the same optical performance. Par versions are available with Medium Flood lenses.
ETC Source Four — buyer FAQs
What is the ETC Source Four and what is it used for?
The ETC Source Four is a professional stage luminaire made in both profile and par configurations. Profile versions are available as fixed-angle or zoom units, with zoom ranges such as 25 to 50 degrees and 15 to 30 degrees, in 575W and 750W outputs. It is used in theatres, concert venues and corporate events. A Lustr+ LED variant offers energy-efficient output alongside the traditional lamp-based options.
Who makes the Source Four and where does it sit in their product range?
The Source Four is made by Electronic Theatre Controls (ETC), an American manufacturer founded in 1975 and known for fixtures, lighting control consoles, and dimming systems used across theatre, live events, studio and architectural applications. The Source Four is ETC's core professional stage fixture line, spanning profile and par types, multiple wattages and both traditional lamp and LED variants.
What are the key optical features of the ETC Source Four Profile?
The Source Four Profile uses a faceted dichroic reflector that removes approximately 90% of infrared heat from the beam, keeping the light cooler on stage. It pairs this with a super-efficient HPL lamp and a two-plane stainless-steel shutter blade assembly housed in a rugged die-cast aluminium body, giving precise beam control suited to theatrical and production use.
What should I check when buying a used ETC Source Four?
Check which variant you are buying: profile or par, fixed-angle or zoom, 575W or 750W, and whether it is a lamp-based or Lustr+ LED unit, as these affect compatibility and running costs. Confirm the zoom range and lens type match your application. Par units may be fitted with specific lenses such as Medium Flood. Used listings on this page carry a 21-day warranty covering major functional faults; the buying guide at 10kused.com/used-av-equipment-guide covers the full process.
What drives the price of a used ETC Source Four?
Used Source Four prices vary according to wattage (575W or 750W), configuration (fixed-angle or zoom, profile or par), and whether the unit is a standard lamp version or the Lustr+ LED variant. Condition, the zoom range, included accessories and whether units are sold individually or as part of a larger package all influence cost. Check the live listings on this page for current pricing.
