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.
