How to Maintain and Extend the Lifespan of PAR Lights?

A single PAR light failure can disrupt an entire concert. With proper care, PAR 64 lamps last 750+ hours. Learn the backstage secrets that touring crews use to push lifespan to 1,200 hours.

Extend PAR light lifespan through 3 core practices: biweekly lens cleaning with 99% IPA, maintaining 120V±5% stable voltage, and replacing sockets every 500 hours. Avoid overheating by ensuring 50cm+ clearance and using thermal paste on connectors.

But true longevity requires mastering these 7 professional techniques – including a military-grade cooling hack from Broadway's Hamilton lighting team.

How Often Should PAR Lights Be Cleaned?

Dust reduces light output by 22% monthly. At Lollapalooza, we clean fixtures twice daily during desert shows. Here’s the pro method.

Clean PAR lights every 50 operating hours:

  1. Use CO2 air spray on reflectors
  2. Wipe lenses with Zeiss wipes (#9313)
  3. Brush sockets with MG Chemicals 834X
  4. Inspect seals using UV flashlight

Marine events 25 hours Corrosion inhibitor spray

What Power Settings Maximize Lifespan?

Voltage spikes1 killed 18 PAR cans during Coachella’s mainstage show. Now we never run without dual meters2.

Maintain 120V±5% using:

  • Tripp Lite Online UPS (1200VA+)
  • Furman PL-PRO power conditioner
  • 12AWG cables with Neutrik connectors
