Frequently Asked Questions

Q. How do these LED lights compare based on other growing methods?
A. HID and T5 (fluorescent) grow lights have been the market standard for horticultural lighting for decades. Each of these technologies uses a bulb that has been filled with harmful gases such as mercury which are ignited or “excited” by a filament. Light is emitted from the bulb in a 360° area and reflectors are used to re-direct light downwards toward plant canopies. The bulbs are limited in the spectra they are capable of producing depending on white kinds of phosphors (CFL) or gases (HID) are being used in the bulb.

HID and T5 technologies share many inefficiencies such as high power consumption, high heat output, frequent bulb changes and improper spectrum. While these lights have been the standard for decades, LED Grow Lights stand to replace these systems with far greater efficiency and convenience. LEDs present many advantages over alternative light sources including lower energy consumption, longer lifespan, smaller size, faster switching, less heat and greater durability/reliability. Typical LED lifespan is rated at 50,000 hours at which point light output has degraded only 30% from new.

In a side by side comparison between the Hydro Grow 336X-PRO LED Grow Light and a 1000W HPS it was proven that the LED produced higher PAR output and deeper penetration over the same 4′ x 4′ area while using approximately 55% less energy. The 336X-PRO also comes better equipped with a spectrum that has been proven by the University of Washington to produce up to 1.7X the dry yields at the same intensity level as full spectrum “white” lighting like HPS

Q. What is a LED?
A. LED stands for Light Emitting Diode. LEDs are small semiconductors very similar to computer chips, however rather than processing data they are “programmed” to emit narrow wavelengths of light at incredibly high efficiency levels. Over the past 50 years it has been documented that LED efficiency increases 20x per decade with costs decreasing 10X over the same period. This occurrence is now known as Haitz’s law, which has enabled white LEDs to become the most efficient light sources on earth at over 200 lumens per watt (2012). Similar to computer chips, LED efficiency will continue to improve with time becoming up to 20x more powerful and 10x cheaper every decade

Q. Why 3W LEDs are Better than 5W LEDs?
A. There is a common misconception with single-chip LEDs that “Bigger is better”, however this is precisely the opposite of the truth. As with all things electrical, the more current you drive through an object the hotter it will become, and with LEDs the #1 cause of failure and premature degradation is heat. While LED manufacturers around the world are working to improve the thermal handling of 5W LEDs, they are presently incapable of matching the efficiency of 3W models

Q. How do LEDs Produces Light?
Unlike traditional bulbs which rely on a filament for current to pass through, a LED passes current from anode to cathode through gold wires that are bonded to the LED chip. The electrons passing through the chip recombine in holes within the chip to release energy in the form of photons. This effect is called electroluminescence.

A LED is usually small in area (less than 1 mm2), and uses integrated optical lens to shape its radiation pattern. Each chip is affixed to a heatsink slug at the solder connection point, which dissipates heat away from the chip and to a larger external heatsink. Heat is the #1 cause of failure for a LED and temperatures above 125° F will cause immediate lumen loss to the LED while speeding up light degradation.

If you’re interested in just starting seeds indoors, compact fluorescent lights will do just fine and are a low cost way to get started.
Q. What wavelengths do these lights utilize?
Hydrogrow LED growing lights produce 440nm blue, 470nm blue, 525nm green, 640nm red, 660nm red and 740nm far-red creates a perfect spectral blend promoting vigorous growth and plentiful harvests
