The difference between 90 Watt vs 180 Watt LED Grow Lights
Advanced Platinum P300 – Our Top Pick for 2018!
Firstly, there are multiple configurations and sizes of LED grow lights available on the market. The question that is always asked is what is the right size and model of LED Grow light for your application. Many times the question is how does wattage make a difference. Such as the difference between 90 watt vs 180 watt LED grow lights. The correct answer depends on the size of your grow room and the plants you are growing.
90 Watt LED Grow Light
LED Grow Lights produce about 100 lumens per watt. And your plants will normally need between 1,500 and 3,000 lumens per square foot of plant. The low end of 1,500 is adequate for normal growing plants and the high side of 3,000 lumens is for some types of flowering plants. If you have a plant grow area of about 2.5’ by 2.5’ that would be about 6.25 sq ft of area. It would then require a 90 watt LED Grow light that produces about 9,000 lumens for normal growth.
180 Watt LED Grow Light
That same area of flowering plants discussed above of about 2.5’ x 2.5 ‘ could require up to 180 watts of LED grow lighting. Or 18.000 lumens for the flowering phase of some plants. If you are just dealing with growing non flowering plants then that 180 watt LED Grow light would produce about 18,000 lumens. That would cover a 12 square foot growing area or an area of about 3’ x 4’.
Lastly, the most popular LED grow lights in the 90 – 180 watt size range are the round LED Grow Lights. Commonly referred to as “UFO led lights” or “PUCK led lights” due to their circular construction and 2”-3” thickness.
