Led courtyard lamp long good or single head
Long exposure area is better than single head relatively wide some.
Single head, of course, single head less waste,See your demand, to achieve what kind of lighting effect
The upstairs to answer very professional. Lamp holder, the more the better, the single head can't be used if it is broken, the bulls' bad a lighting effect, and long heat dissipation is better than single head (this is important!) .
