Usually it’s very easy to get confused about the lifespan for Solar street lamp system and LED light source.
Now most of the LED chip can reach 50000h lifespan,slightly better ones even can reach more than 100000h.But the Solar street lamp system include many other parts,for example, the batteries,controller,the solar panel….and each of them has different lifespan.Now a standard one can work 3 years or longer,but a bad one will less than 2 years.So it will directly increase the cost of maintenance.
In a word,when you choose the solar street light,you must take those all into consideration.
