SMD feature with good heat emitting,high lumen flux and low optical decay(3% in 1000 hrs), For DIP LED,the heat is emitted through the pins,and high optical decay(above 15% in 1000 hrs).It means that SMD led tube lights is about 5 times longer life time that DIP led tube lights.
also For DIP LED, Operated by handwork only,inconvenient for automatic produce and management,and easy to cause many problems by human factor. Because of these reasons,now we don’t produce any DIP LED tubes.

All led lights have led driver inside it,so the led light don’t need ballast.When you install led lights,you need to remove the ballast.
