The LED "bulb" cannot be replaced. However, LEDs are known to have very long lifetimes. LEDs typically do not "burn out." The typical failure mechanium is a gradual loss of light. I do not know the rated life for the LEDs in this lamp, but LEDs typically last for 50,000 to 70,000 hours before their output has dropped by 30%. 50,000 hours would be about 5.7 years of continuous operation, or over 17 years at 8 hours per day.
