Trimlight provides an industry-leading Lifetime Product Warranty covering the components of the Trimlight system for the life of those components — up to 40 years with proper use. The bulbs have a 50,000-hour lifespan. Running the system 24/7 dramatically shortens the lifetime because of heat dissipation, so we recommend a sunset-to-bedtime schedule. For Tennessee customers, Northpoint Trimlight is your warranty point of contact — we coordinate every warranty claim directly with Trimlight HQ on your behalf. Detailed warranty terms are available at trimlight.com under the warranty PDF.
