High Pressure Sodium Lamps Q & A
Q: How long do HPS lamps typically last?
A: Quality lamps last 18,000-24,000 hours with proper maintenance.
Q: Can HPS lamps be used with dimmers?
A: Special dimmable ballasts are required - standard models aren't compatible.
Q: Are HPS lamps being phased out?
A: While LED alternatives exist, HPS remains popular for cost-sensitive applications.
Q: What's the warm-up time for HPS lamps?
A: Typically 3-5 minutes to full brightness, with pulse-start models being faster.
Q: How do HPS lamps compare to metal halide?
A: HPS offers better efficiency but poorer color rendering than metal halide.
