What"s the difference between isolated and non-isolated driver?
The isolated driver transfer the voltage from AC220V into lower voltage by transformer, then using electron component turn the lower AC into DC to supply LED.
The Non-isolated driver turn the AC 220V into DC through the electron component to supply LED directely. Isolated driver is more safe then non-isolated driver,and isolated quality is stable then non-isolated,but the price for isolatedis higher than non-isolated
