What are the conditions for waterproof LED light strips?
The 12V/24V low-voltage ordinary LED light strips can also be lit in water, but this is not called waterproof LED light strips. If it is used in water for a long time, it will cause oxidation of the circuit board and lamp bead pin, which will affect the use effect and life. Seriously, it can cause short circuits and cause unpredictable danger. At present, the waterproof technology of waterproof LED light strips can be mainly divided into the following four types:

1. LED light strip IP65 waterproof: It is usually also called surface Epoxy waterproof light strip, currently made of epoxy resin and PU glue. The LED light bar is placed flat on the surface of the epoxy table, and the LED light bar is fixed on the back side with double-sided tape, and then a layer of glue is applied on the surface of the LED light bar to protect the surface from water.

2. LED light strip IP66 waterproof: It is usually also called hollow full casing waterproof light strip, the general use of the casing is silicone full casing and PVC full casing.

3. LED light strip IP67 waterproof: It is usually also called semi-casing Epoxy waterproof or semi-casing glue waterproof, the bottom is a semi-casing sleeve and then do the glue or glue treatment. Waterproofing of the glue will affect the heat dissipation of the light bar and the long-term use will cause the sealant to fall off.

4. LED light strip IP68 waterproof: It is usually called full casing glue waterproof or full casing pumping waterproof, is currently the highest waterproof level among waterproof LED light strips can be completely used in water.
