Initial Thoughts…

When it comes to LED grow lights, you look at 3 things: light penetration, spectrum, and coverage at the proper height. The King Plus 1500W LED Grow Light is probably best suitable for grow rooms or grow tents under 4.5′ x 4.5′. What separates it from other lower-priced LED Grow Lights is the fact that it uses 10-watt chips, which allow for a brighter, more efficient light when it comes down to the canopy and the harvest – more penetration, more buds.
Digging a little deeper, these lights are in more than an affordable price range. Considering the brightness and the price of this unit, we believe that this one is a no-brainer. Still not convinced? In that case, continue reading. Below is a detailed analysis of this amazing LED grow light A complete analysis of the King Plus 1500W Double Chips LED Grow Light Over the past few years, the LED grow light technology has been leaping like insane. A great example of the technology leaping forward is an amazing King Plus 1500W Double Chips LED Grow Light. An amazing 10W double chip LEDs can output up to 1500 watts of energy towards your plant. You see, the 10W chips are actually made of 2 5W chips laid out in a grid pattern. These are twice as bright as normal LEDs. The double chip LEDs provide a uniform light and PAR value of 660 directly below the unit. The life expectancy of the unit is 50,000 hours and it has a “Zender protector” that makes sure the unit will continue to work even if some of the LEDs die. One of the best things about LED grow panels is the way that they can work with various light ranges at once. This is accomplished by embeddings diverse hued LEDs and also IR and UV chips in with the general mix of onboard LEDs. Full range LED grow lights are outlined particularly to create the correct wavelengths of light that are utilized by your cannabis plants. The grow light discharges a purplish shading because of the diverse hued chips that are being utilized at the same time. The right light range contains a mix of red, blue, yellow and white lights. Over those hues, infrared and ultraviolet are likewise included. Every one of these ranges together makes up the impacts of summer day sunlight.

Coverage & Light Height

This King Plus LED Grow Light has solid coverage in the veg stage of roughly 5′ x 5′. When you switch to flowering, I would not exceed a 4.5′ x 4.5′ grow area. This easily provides light for up to 10 plants. I think you could flower easily up to 5×5 if you raised the light a few inches. Suspending the King Plus Double Chip LED Grow Light is very simple to do. With the included free-hanging snares, you can associate each clip to the metal eyelets situated on the top side of the panel. Changing them is simple since they fasten into position and can be moved up or down easily. In any case, making sense of the stature that you have to suspend the panel over your plant’s covering can take a touch of experimentation. You will see the recommended light height and coverage in the image to left.


This is where I feel there can be some improvement. Not only did it appear that each fan was spinning at a different speed, but after only 17-18 days into veg, one fan began to make noise and failed a few days later. Luckily, these LEDs do run fairly cool, however, they need cooling for internal components which did worry me a little. Having a normal oscillating fan in the tent took care of any additional heat that could have been disruptive, but the remaining 2 fans did the job and kept the light cool enough to get through the entire cycle.
