How to choose high-quality LED plant lights up the plants fill light
LED fill light already exist in the market for a few years, the first generation of LED does not have enough advantages in plants fill light hid competition, but the latest design high quality led enough to fill light system mentioned MH and HPS .

Here’s how to help savvy you choose high quality led grow the fill light products: To select high power led growers should choose high-power LED products, low power led insufficient to support the entire growth process of the plant. Should be greater than 1W high-power LED. Series of LED products include: Cree XR-Lamp for LUXEON Rebel and LUXEON 3W K2 5w series led products include: LuxeonIII and the OSRAM Platinum Dragon series.

High power LED in the bottom of the usually integrated a large piece of metal used to the heat.Choice brand long life led HPS to life is usually at 20,000 hours, the actual use of 5000-10000 hours, this is because the long sodium lamp illumination will decline. Led the life of the product quality is generally between 50000-100000 hours, and the output illumination of the manufacturer before leaving the factory are set at 70%. High temperature environment, if the heat do not, life will be a sharp decline. Led thermal design is very important, it must be in the course of life factors led assess, choose a good LED products have good heat dissipation 3.led like your computer’s CPU cooling fan , led to the need for good cooling.

The good led fill light system should have a large heat sink, and cooling area as large as possible, if a fan is the best, so as to improve the life of the led. Dc power supply – constant current output circuit to have a goodThe electronic circuits supply of LED life is an important consideration. Assessment, LED lights.

LED drive circuit, like a metal halide electronic ballast input power into DC power, AC voltage and LED current level. The most important job is to provide a constant DC current, even over time and temperature to control the the LED voltage change, early failure led products are basically related to the design of power relations.

Good design of dc power led drive should change with time and temperature, the output current remains unchanged. Possible to adjust the output spectrum. To adapt to the growth of plants.
