Can Poor Ballast Efficacy Violate Energy Codes?
Yes—poor ballast efficacy can violate energy codes when the lighting system’s watts-per-lumen performance causes the installation to exceed code-required lighting power limits (LPD) or fail mandated high-efficacy equipment provisions. Modern energy codes increasingly regulate total installed lighting power and require efficient components, making low-efficacy ballasts a compliance risk even if lamps are unchanged. This article […]
