When it comes to LED grow lights, there are so many brands and types to choose from. Manufacturers will try to sell their product based on raw specs alone, citing figures like wattage as though it were a good enough indicator of how well it can help your plants grow. To both newbies and experienced gardeners, the sheer number of options for LED grow lights can be intimidating. Because of this, we’ve looked at dozens of different models and compared them to give you a shortlist of the best 100 watt LED grow lights.
For the purpose of this review, we are comparing only the 100 watt options. As previously mentioned, wattage is only one in several factors which will determine the performance of the LED light. We also take a look at the quality of the LED bulbs and the quality of the LED circuit. Depending on the manufacturer, a certain 50w light can actually perform as well as a 100w light from another brand. Some brands also offer a different type of LED technology that makes them stand out from the competition. And of course, energy efficiency is also taken into account when selecting the best of the best.
We also consider the type of customers who want to buy these kind of products. There are those who will be more price-conscious and may be willing to cut a few features to save some cash. There are those who can spend a bit more but want durability and efficiency to save them money in the long run. There are others who will need a very specific set of features, such as waterproofingif they plan on using the lights for hydroponics. Still there are those who want the latest technology and all the bells and whistles their money can get them. Through this list, we want to provide a viable option regardless of your budget and intended use.
