Quality of light
The Mars Hydro 300W LED grow light consists of 60 small 5-watt Epistar LED lights. These LEDs produce a light equivalent of 300 watts. Fortunately, it consumes only 135 watts. Furthermore, it gives out a full spectrum light with a wavelength range of 430 ~ 440 nm, 450 ~ 475nm 620~630nm, 650~660nm. Its 5-watt chips are powerful enough for deep canopy penetration. They are better compared to the 3-watt chips used in most other LEDs. This has been fine-tuned to suit not only cannabis but also flowers and vegetable plants.
Light spectrum
The Mars Hydro 300W offers a well-balanced spectrum that incorporates a broad range of wavelengths: 430 ~ 440 nm, 450 ~ 475 nm 620~630nm, 650~660nm, and white. This spectrum is perfect and suitable for all stages of growth. This is the reason why many growers have said that LEDs provide faster, healthier growth since they know exactly which kind of light to deliver. With around 140 watts of power consumption, the diodes aren’t driven to their maximum capacity. In order to provide longer lasting parts, MarsHydro made a smart choice by not running all of the LEDs over a stable limit. Each diode is behind a small lens that projects the light in a mixed 90 and 120-degree pattern to provide better coverage to the garden canopy. The balanced full-spectrum is what the plants are craving and it can deliver it with the right amount of intensity.
Coverage
The optimum growing area is limited to 24-inch x 24-inch for a grow light like this. We recommend that you use it for an18-inch x 18-inch area during flowering for better results. Each diode of the Mars Hydro 300W grow light is covered by a small lens that focuses the light on to the canopy. With a mixture of 90 and 120-degree angles, it provides great coverage and penetrates with good intensity. It’s not super-powerful so it’s perfect for smaller plants or small-scale grows like smaller grow tents, the case grows, stealth boxes or closet growing.
Cooling
We all know how any type of light can be capable of emitting heat. If you are concerned about too much heat, we are happy to let you know the 300W Mars Hydro gives out less heat compared to other grow lights. Thus, making heat less of a concern. Inside there’s a large diameter cooling fan that’s constantly spinning when the light is turned on. It blows cool air over the heatsink that dissipates the hot temperatures away from the diodes to create a better environment for them to run at their best efficiency.
Safety Features
These cooling mechanisms mentioned above seem to be doing a very good job when it comes to safety. It protects the diodes from failure and burnouts. Another smart feature that we noticed with this Mars Hydro grow light is not driving diodes to their maximum capacity. Running LEDs over a stable and comfortable limit ensures that the parts last longer. In addition to that, they serve to protect each diode. If you look at the arrangement of the diodes, you’ll also observe a small protector situated right next to each LED. These are designed so that if one diode burns out, it won’t cause a successive reaction and shut off all of the diodes. This affordable LED grow light has a heatproof tube. This tube effectively eliminates the risk of the LED light catching fire. Their safety features made them pass the US authoritative ETL certification tests.
