How to choose a high quality LED grow light

There is confusion of many growers : How to choose a high quality led grow light? Does the cheap light cause cheap results? How to evaluate the quality of light ?

Professional grower looks for the following features in a high-quality led grow lamp.

1. Isolated power driver.

The electronic circuit powering the LEDs is an important consideration when evaluating LED lights. The LED “driver” circuit is like an HID ballast.Isolated power  converts AC input power into DC power at the proper voltage and current level for the LEDs, while protecting the lights from electromagnetic interference , also protecting the person who would interact the lights sometimes from electric shock.

2. Large Size LED Chips

Large size chips contribute to quick heat dispelling, It has good heat resistance thus the lamp beads will not be damaged easily. The life expectancy is increased greatly.

3. High-efficiency Cooling System

Like the CPU in your PC, high-power LEDs must be cooled with a heat sink and fan. Because high-power LEDs do not radiate any heat, the metal pad provides the only path for heat to leave the LED. Heat flows from the LED die, through the metal slug, through the circuit board, into a heat sink and then out to the surrounding air.

Look for LEDs mounted on a metal-core printed circuit board (MCPCB), a space-grade technology used for operating electronics at high temperature. An MCPCB conducts hundreds of times more heat compared to the typical fiberglass circuit board. An MCPCB is required for the high power levels that LED horticultural lights endure.

4. Constant-Current Driver Circuit

Proper LED driver circuits supply a constant DC current, holding steady as the LED voltage changes with temperature. Look for the words “constant-current” in the horticultural light’s LED driver specifications.

5. Rigorous Testing

The LED lighting marketplace can be confusing. How does one separate fact from fiction when reading manufacturer claims about electrical savings and plant growth? Look to see if the manufacturer possesses an engineer groups to conduct the test for all finished products.All in all,whether greenhouse growing is your livelihood or your hobby, don’t risk the health of your crops or your budget on inadequately tested LED lights.
