LED drivers fail before LED chips — buy fixtures with replaceable drivers

The LED chip itself can last 50,000+ hours, but the driver (power supply) typically fails in 5-7 years. Integrated LED fixtures with sealed drivers become expensive disposable units. Fixtures with replaceable drivers (look for 0-10V or DALI driver bays) let you swap a $15 driver instead of replacing a $200 fixture. This is especially important for commercial and hard-to-access installations.
