Best Led Grow light 2019 : Buying Guide
have already provided you with a list of the best LED grow lights available in the market. But just choosing one of the above may not be appropriate for your indoor gardening requirements and hence you need to consider a few factors and know a bit more about a few integral details before you actually go on and get the Grow light of your choice. Let’s have a look at the factors that may affect your decision.
Getting the basic things right. This is the first thing that you need to consider even before you start searching for the grow light of your choice. You need to identify and enlist the area that you wish to cover. The Grow light coverage area changes with the height at which it is hung and also the state at which the plants are. For a particular LED grow light the coverage area is more during the vegetative state than the blooming stage. So basically you can narrow down your search with this basic filter. For large areas you may need more than one LED grow light unit and hence it’s recommendable to choose one that is daisy chainable so that a single kind of LED grow light can lit up your entire grow area and there is uniformity in the light received by the various plants in that area.
PHASE OF PLANT GROWTH and SPECTRUM:
The phase of plant growth is very important when choosing the LED grow lights. If you are not looking for a specific phase and want a light to suffice through all the growing stages then you need to choose a full spectrum LED grow light. Now full spectrum grow lights are available in a wide range of band options. The best ones or the ones that will promote development and growth from germination to flowering are the ones that have a balanced ratio of red, blue and white lights along with a share of UV and IR rays. The best ratio of red to blue is 9:1. Some LED units have dimmable knobs to control the intensity of the lights while others are equipped with switches to alternate from VEG and Bloom stages. Switching both of them together will give a full spectrum light. The PAR/Lumen value is also essential in determining the penetration value of the light. The PAR value is determined in accordance with the height. The higher the PAR value the better it is.
The power of the HID light which can be replaced by the LED unit is extremely important. This helps you choose as to what strength of LED you need to buy. The numerical value expressed at the end of an LED model is not the HID equivalence and consumers are often mistaken by it. For eg. V1200 refers to the total LED wattage or the wattage of an individual LED multiplied by the number of LEDs though the HID equivalence of V1200 is 1000W.
The quality and the make of the LED chip along with the individual power and the technology makes an important mark in the LED grow light unit. Most high end LED grow lights use Bidgelux/Epileds LEDs or Epistar LEDs. Some LED grow lights use a double or dual chip technology wherein a single diode is replaced by two diodes together. They are almost twice as brighter and better. Some LED chips have a Zener protector attached to them to enhance the durability of the product. The protector eliminates the risk of breaking the circuit when a single LED is not working and hence the remaining unit still runs when attached to one.
The electrical consumption of the LED grow lights are generally much lower than any HID unit, but you get LED units which have the same power and give the same yield but consume much less electricity. Going for such a model will help in lowering the running cost.
Though the heat generated by LEDs are much less compared to any other kind of grow lights, even then the heat generated has to be successfully dissipated or else it may burn and disrupt the LED circuit and also increase the temperature of the growing environment and affect plant growth. Too much heat can even burn the plants. Most LED grow units have high grade aluminum heat sinks and cooling fans to take care of this factor.
Lastly and may be one of the most important factors is the budget you can shell out for the unit of your choice. Though our list includes mostly inexpensive affordable variants, some very durable and premium quality one are a little expensive but will prove to be cost effective in the long run.
With this we come to the end of our article. We have provided you with a proper buying guide as well as a list of the best LED grow lights 2019 in the business. Our list is a comprehensive one and varies through the entire power range so that you do not have difficulty in finding one that would suit your needs.
