Tubular waterproof lights are waterproof, corrosion-proof and dust-proof. The respirator design quickly balances the pressure difference between the inside and outside of the lamp to prevent water and dust from entering the inside of the lamp to ensure the normal operation of the lamp.
Compared with the traditional waterproof lamp, it is more convenient to install. It only needs to open the orange end cap of the Led Tube Light, thread the wires in, and connect the terminals.
Led Tube Light can not only be linkable in series but also Parallel Connection, as shown in the figure below.
There are two installation methods, one is a sling and the other is ceiling installation. There are two types of ceiling installations, one is fixed and cannot be moved, and the other can be rotated 180°.
IP66 LED Tri-proof Light has emergency and sensing functions, which is very suitable for parking lots, warehouses, basements, workshops, etc.
