Solar lights have a deservedly questionable reputation. They break easily and often are far too dim to offer any practical light. For years, the only real way to buy good solar lights was to check the lumen rating - a measure of how bright the lights are, listed in the specifications.
However, you might end up with a dud even if you do your due diligence and check the lumen rating. Energy and lighting experts allege that some solar lighting companies fudge their lumen numbers, either by swapping out the effective lumen numbers for the raw lumen numbers, or by making them up entirely.
