The smaller decorative solar lights usually just work for a certain number of hours – usually 6 to 8 hours maximum- each night on a full charge. For the more powerful security, pathway and area solar fixtures, there are usually a number of options built into each fixture.

• Work steady at full power- usually does not last for more than 6 to 8 hours
• Work steady at 50% power (or similar factor), and motion sensor activation will brighten light to 100% power
• 100% power Activation by motion sensor only.

In many security and area light fixtures, operation in the 2 reduced power modes can allow the fixture to be able to have back up power (without recharge) for 2 nights or longer.
