One of the most common questions for industrial marijuana growers is: “what type of LED grow light should I look for?”
I’ve been experimenting with new LED lights to get a real sense of what’s on the market. Buy, I am not going to sell to you on any brand, now I want to talk about what you should pay attention to before investing real money to buy LED plant lights.
You are always looking for at least 3W chips, and no chip less than 3W can provide enough consistent light coverage for your plants. This means that each chip needs to be 3W instead of 1W LED, so keep this in mind when reading the instructions. 3W chips provide the best quality in white, blue and red.
This is also important; you want to read the product description to get the total output. How many units does the lamp claim? It can be 300W, 400W, 600, or even 1000. Always check the output and look for at least 300W.
Understand that when it comes to LED, you can’t always get 100% power, so the final wattage is usually less than recommended, and the chip will always burn out regardless of the quality, so the higher the wattage, you can compensate for the wattage loss.
Remember, red, blue and infrared are also important when growing industrial marijuana, so you should stick to the ideal par value. Look for blues ranging from 440 to 470nm, with tearing ranges from 640 to 660nm.
These lights stay on for most of the day, usually 15 hours at a time, so make sure they have internal fans to protect lights and fans to protect plants. If it is too hot there, it may damage the plants.
LED lights operate at a lower temperature than HPS bulbs because they emit only about 15 to 25 percent of their energy as heat, but the heat occurs behind the LEDS bulb, so the area needs to be protected. The outer or inner area of the rear of the high-quality lamp will have a thick aluminum heat sink to remove the heat from the chip.
High-quality lamps and lanterns will have an optical lens that magnifies light and increases the nutrient permeability of plants by about 25%. This makes the lamp more expensive, but it is definitely worth it.
LED should have a warranty, preferably one of 5 to 10 years. In fact, the service life of LED of this nature is about 10 years, especially in some of the more expensive panels. Look for sturdy panels made of aluminum, steel or non-breakable materials.
As mentioned earlier, looking for lights with a warranty period of more than one year, the life of the LED is as long as 10 years, so I am a little skeptical about manufacturers who only offer an one-year warranty, because it indicates a low cost to make a shell or cable system. I usually want the parts to have a 3-year warranty.
In any case, the parts guarantee will be better, because no matter which part needs to be replaced, the light bulb will continue to work. You can easily replace the missing parts when they arrive, while your plants can still get the nutrients they need.
