How many lumens in a solar street light?
Take the lumens all in one solar street lights for example, if we use 150 lumens per watt led solution, we need to set 70 watts solar panel and 12V 30AH lithium battery. If we use 200 lumens per watt led solution instead, led power can be 30 watts only. Then we can low down the solar panel power to 50 watts and lithium battery to 12V 22ah.
