Introduction: Are LEDs a Good Choice for Growing Cannabis?

Average Yields: 4+ ounces – keep in mind that the strain (genetics) and any plant training you do makes a huge difference in your final yields
Sites like this one wade through all the crappy choices and find the quality lights. And they don’t always have to be the most expensive options either (Phlizon and Spider Farmer are both good examples of this). You can get really good LED grow lights for not too much more money than their HID plant light equivalents.
If you want to go with quantum boards, but HLG lights aren’t in your budget, Spider Farmer is an excellent backup. They also use Samsung diodes and Meanwell drivers, but sell at a considerably lower price.
During vegging, plants require more bluish light with wavelengths that range between 430-460 nanometers
The Phlizon COB lights ship with an adjustable ratchet hanger, a hanging kit, a power cable, grow glasses and a thermometer and humidity monitor. They are covered by a 2-year factory warranty and have a 30-day money back guarantee.
The Bad News
If you are on a strict budget, Mars will probably be the best option for you. Likewise, if you need UV light, the two SP series lights are the only ones that provide that.
Mars does not use Samsung chips or Meanwell drivers. That keeps the costs down. They use Chinese copies of both, though there is some confusion about this. Unfortunately, the confusion is down to Mars lying. When they first released these lights, they claimed to be using Meanwell drivers, when they were actually using knockoffs.
For LED lights, the most widely used measure of intensity is PAR (technically, it is PPFD and not PAR, but most still refer to it as PAR). It stands for Photosynthetically Active Radiation and is used to measure the amount of light in the wavelengths that plants use for photosynthesis. Some brands will list the lumen output, but that isn’t all that useful for grow lights.
Best COB: Phlizon COB Series LED Grow Lights
But they have been working hard to improve those areas and now deliver excellent customer service and their quality control has improved by leaps and bounds, too, ever since they’ve moved their production from China to Tennessee.
HLG is the only company on this list that manufactures in the US (Advanced Platinum is also a US brand, but they manufacture in China). What really sets them apart is the efficiency of their lights. They deliver an incredible output considering the wattage they consume.
