Second, take a look at a battery compartment. It may contain one or multiple batteries, and of course the more batteries the better.
Surely the light fixtures with multiple LEDs and multiple batteries are the most expensive. But it's hard to say that such expensive models are definitely the best purchase, because technology is advancing so fast that in a couple of years even the cheap lights will be more bright and long-lasting than the top ones now. So it is better to find the acceptable balance between the characteristics and the price of the solar LED light. Another smart decision will be shopping for solar lights at the end-of-season closeouts, as you can get really big discounts.
