Smart startup and long-term care

• Programmed Start operation preheats the lamp before ignition, a design choice intended to help extend lamp life.

• Internal surge protection and inherent thermal protection guard against voltage spikes and temperature changes, contributing to safer operation.

Safety, standards, and reliability

• FCC Part 18 (Class B) EMI/RFI compliance helps minimize interference with nearby equipment.
