LED Lamps Bulbs The non-isolated means has a direct connection at the the LED load end and the 220V input and therefore the touch load there is the danger of electric shock. Only a very thin insulating layer of aluminum plate isolation between 220V and aluminum is usually not easy by CE and UL.

Isolated means the isolation transformer isolation in the input terminal and an output terminal, such a transformer may be the frequency may be high frequency. However, both the input and output isolation. Can avoid the risk of electric shock. Also easy by CE or UL certification.

A. Built-in Power LED fluorescent lamp power consumption LED Light Module

The biggest advantage is the built-in power supply can directly replace the existing fluorescent lamps without the need to make any changes to the original wiring. This advantage of the built-in will have to pay it? Indeed, and that price is not small. From ordinary fluorescent lamp ballast structure Speaking:
