About the Robert Juliat QUINCY Range
The Robert Juliat QUINCY Range is a series of 575W MSD discharge profile spots built around an electronic PSU with hot restrike capability and a high colour temperature of 6000K. Three zoom variants cover different throw requirements: the 423SX spans 28 to 54 degrees, the 424SX covers 16 to 35 degrees, and the 421SX offers a tighter 11 to 26 degree zoom. Lamp life is rated at 2000 hours. A notable design feature allows the lamp base to be exchanged with that of the compatible 600SX tungsten series, letting users convert a standard tungsten theatre profile spot into a discharge unit, making the QUINCY a cost-effective upgrade path for existing rigs.
Robert Juliat QUINCY Range — buyer FAQs
What is the Robert Juliat QUINCY Range and what is it used for?
The Robert Juliat QUINCY Range is a series of 575W MSD discharge profile spotlights designed primarily for projecting logos and images at corporate events and for architectural enhancement. Each unit runs from an electronic PSU with hot restrike capability, produces a colour temperature of 6000K and is available in three variable zoom configurations to suit different projection distances and beam angles.
What are the three zoom variants in the QUINCY series?
The QUINCY 423SX covers a wide 28 to 54 degree zoom, the 424SX offers a mid-range 16 to 35 degree zoom, and the 421SX provides a tight 11 to 26 degree zoom. All three share the same 575W MSD source and electronic PSU with hot restrike, so the choice between them comes down to throw distance and the beam angle required for the specific installation or event.
Can a second-hand QUINCY be used to upgrade an existing tungsten profile rig?
Yes. The QUINCY's lamp base is interchangeable with that of the compatible 600SX tungsten series, which means an existing tungsten theatre profile spot can be converted into a discharge unit simply by swapping the lamp base. This makes a used QUINCY a cost-effective upgrade path for rigs already running compatible Robert Juliat tungsten fixtures rather than requiring a full replacement.
Who makes the QUINCY Range and where does it sit in their lineup?
The QUINCY Range is made by Robert Juliat, a French family-run stage lighting manufacturer with roots going back to 1919. The company produces a broad range of theatrical and live-event fixtures including followspots, profiles and fresnels. The QUINCY sits within their profile spot offering as a discharge-source option, and its lamp-base compatibility with the 600SX tungsten series reflects the company's approach to interoperability across the range.
What should I check when buying a used Robert Juliat QUINCY?
Confirm which zoom variant you are purchasing (423SX, 424SX or 421SX) and ask about remaining lamp life, since the 575W MSD source is rated at 2000 hours. Check that the electronic PSU and hot restrike function correctly, and verify the condition of the gobo holder and lamp base if the unit has been used for conversion between discharge and tungsten configurations.
