LED Glass Tube Light - Better heat dissipation

It is the fact that heat conductivity of Aluminum is higher than glass. But for the normal Aluminum+PC cover type tube light, the heat can only dissipated through the Aluminum, the PC cover doesn't work. 

As for the glass tube light, the whole tube is made of glass. Almost 360 degrees of the product can dissipate the heat. 

And, it is also a fact that the thermal diffusivity of glass is better than the Alunimun. So, not good heat conductivity but larger heat radiating area and better thermal diffusivity, on the whole the glass tube will do better in heat dissipation. 

What's more, glass tube is cheaper than the normal type. We saw glass type tube on the HK lighting fair and so many people are attracted by its advantages. This kind of glass type tube light will become a trend in the future.
