In order to properly light up your flagpole and respectfully highlight your flag, you should aim for a solar light that boasts at least 7 watts or 300 lumens of power. It’s more important that you pay attention to the lumens over the watts, as lumens will tell you how bright the light is. (8) The more lumens a bulb has, the brighter the solar light will be.
Of course, 300 lumens is simply a minimum; many of the products we’ve talked about today offer much more than 300 lumens in brightness.
