What to look for when choosing LED lights for plants

Durability - Obviously you want your LED grow light panel to be well-built and of heavy duty construction. You want to be sure they are made of the best materials possible and the wiring is going to stand up over time. Faulty wiring can create excess heat which is not only bad for your plants but could become a fire hazard. This is another important reason to buy the best quality grow lights you can afford.
Cooling System - LED lights are cooler than their HID and HPS counterparts. However, they should still contain a high-quality cooling system. The heat sink within your system should dissipate the heat created by the lights and move it away from the lighting system and your plants.
Color Spectrum - Plants primarily use red and blue spectrum light to progress through their growing stages. While HID and HPS systems use a full spectrum of light to target plant growth, a good LED system will include both red and blue lights for a perfect blend to help your plant grow. There are some growers who say white LED grow light is the closest to natural sunlight and is therefore better. However, white LEDs include yellow and green light that isn’t usable by plants and is therefore wasted making your grow lights less efficient.
PAR - PAR stands for photosynthetically active radiation. In simple terms, this is the light emitted that is actually usable by plants. Although many manufacturers provide details on lumen output (light visible to humans), for grow lights, it’s more important to understand the PAR output. If your plant isn’t using it, it is wasted energy. Manufacturers PAR data can be misleading as the value often changes from the centre to the edge of the light. The plants under the middle of the light will receive the full PAR value while those at the edges may be getting less light. A high PAR is not necessarily better. In fact, good led grow lights will have lower PAR values because the power isn’t concentrated in the centre but rather distributed evenly.
Wattage - When you see a wattage associated with a LED grow light, it is typically the equivalent wattage you would need in a HID or HPS light to get the same result. So a LED grow light listed as 400W can replace a 400 watt HID or HPS light but the actual wattage of the LED will be far less. This is way LED grow lights are much more energy-efficient. First-time buyers often assume the more wattage a grow light provides, the better. But bigger is not always better. The rule of thumb is you need 32 watts per square foot of growing space for flowering and light-loving plants like cannabis. Low-light plants like lettuces and herbs need only around 11-18 watts per square foot.
Programmable - If you are serious about growing, you’ll want to automate as much of the process as possible, not simply to lessen your workload, but more importantly, to lessen the possibility of human error. The best grow lights on the market offer a full range of programmability including setting light schedules, altering intensity, and customizing spectrums to best suit the individual plant.
