Now most of the LED waterproof power supply is not uniform, so most are relatively small amount. Small purchases, the price is high, but not quite with component suppliers;

LED waterproof power production and related products company's technical staff is not enough understanding of the switching power supply, LED waterproof power supply is made ​​to work properly, but some critical evaluation and consideration of electromagnetic compatibility is not enough, there are still some have hidden; currently there is no uniform standard LED waterproof power supply, most of them are switching power supplies and electronic ballast reference standards;

LED driver higher conversion efficiency to be challenging, especially when driving high-power LED is especially true, since all the light is not output as a clothing school power is dissipated as heat, the power conversion efficiency is too low, the impact of the LED display play the energy saving effect.

Stability LED waterproof power supply: wide input voltage, high temperature and low temperature, over-temperature, over-voltage protection and other issues are not resolved;

First, the overall life of the drive circuit, especially the key components such as: high temperature in the life of the capacitor directly affects the life of the power supply;

In addition, with regard to LED waterproof power supply, compared with the overall constant, constant, although shortcomings by road more, the cost is relatively high. But it can really protect and extend the life of the LED LED, so by constant current is the future trend.

Guangzhou, a sharp Optimax Technology Co., Ltd. (www.crilite.com) - specialized in producing LED waterproof power supply, LED downlights LED panel lights power supply and other products.
