How long does the Aspect™ last and do I have to replace the bulb?

The lights actually have an LED chip (rather than a bulb) mounted directly to the aluminum housing and cannot be replaced. If used for 16hrs/day the Aspect will last 15 years; or 90,000hrs. You do not have to replace bulbs or any components of the Aspect. If the light burns out for any reason within 5 years of the purchase date, just return it to us and we will send you a new one.
