  Waterproof Strip Dimension  

*Non-waterproof : Bare Strip, with self-adhesive backing, for indoor or dry location use.
*Waterproof IP65 : Strip Surface is covered on top with Gel, and with self-adhesive backing. IP65 grade can protect sprayed water from all direction.
*Waterproof IP67: The bare strip is put in a hollow silicone tube and sealed at two ends. IP67 grade can shortly immersed in water.
*Waterproof IP68: The bare strip is put in a U Shape silicone tube, then covered on top with silicon gel, and sealed at two ends, which make it's solid.IP68 grade can be used under water.

How to power/control the strip

When choosing the transformer, the wattage to choose depends on how many pieces light strips it power.And when choosing the transformer, we suggest to use a bigger wattage transformer than the strip rated power to  avoid full load working of the transformer. And a big power transformer do no harm to the strip but good for safty.

Below please find the connection diagram for Single Color Light Strip for reference.

Direct Powered by Transformer Run to AC Wall Outlet, On/Off controlled by a Wall Switch

Light strip On/Off/Brightness is controlled by  Dimmer (Wireless or Hardwire Type available)

#1 Typical connection for one Dimmer to control one string of light bars

#2 One Dimmer to control several strings of light bars by adding Amplifier, and powered by one or several transformers. Note: The strips the Dimmer and Amplifer loaded with cannot exceed their rated max value. And in theory, you can add endless Amplifiers after the Dimmer.
