MarsHydro Reflector144 is an energy-efficient, powerful, and reliable grow light that uses 144 Epistar LED chips to produce tweaked light of pre-determined wavelengths so as to support crop cultivation during the different stages of the crop cycle, hence making it applicable for hydroponics, greenhouse farming, and indoor gardening.

MarsHydro Reflector144 is a powerful and reliable grow light specially built for hydroponics, greenhouse farming, and indoor gardening. It’s unique reflector has a compact design with its light-collecting and reflective properties allowing it to focus light onto the crops while minimizing light wastage through dispersal.

The LED panel of this model contains 144 Epistar LED-chips. Each chip can draw up to 5 watts of electrical power, and this gives the unit a theoretical maximum power draw of 720 watts. However, in reality, the unit draws up-to 303 watts and testifies to its energy-efficiency design, especially its superb internal circuitry which minimizes power wastage.

This unit has several distinct advantages and 2 main disadvantages which are listed hereafter, along with a verdict about the product. Thereafter, there is a Review of Mars-Hydro Reflector-144 Led Grow-Light.

Overview of Mars-Hydro Reflector-144 features

mars hydro reflector MarsHydro Reflector144 is an energy-efficient and powerful grow light built to replace the 400-watts high-intensity discharge (HID) lamps including the high-pressure sodium (HPS) and metal halide (MH) grow lamps. The panel of this unit is compartmentalized into 3 pockets of equal size, with each pocket housing 48 Epistar LED-chips. The chips are placed to provide a view angle of either 90 degrees or 120 degrees.

The luminous efficacy of these chips is improved by the reflector design which prevents light dispersal into non-productive areas of the indoor garden. This model is designed, built, and tested by MarsHydro, a Shenzhen-based company.

This compact model weighs about 15 pounds (or 6.7 kilograms) and is 33 inches long and 10 inches wide, while its thickness averages 3 inches. Its width and height allow it to be fitted into tight roof spaces, while its length allows it to illuminate a large surface area. Still, the unit can be suspended above the plants using strong hanger cables.

The manufacturer recommends that the light is hoisted at least 18inches above the crops. At the 18-inch height, the light can illuminate an area of 4.5 feet by 2.5 feet, while its core coverage (or bloom) area is 4 feet by 2 feet.

mars hydro reflector 144 fans

There are three powerful cooling fans at the top of the case.

This product is powered by 85-265 AC volts and can produce light of differing wavelengths and luminosities. The electromagnetic spectrum of its white light ranges from 430-nanometers to 670-nanometers; while its infra-red light is made of electromagnetic waves of whose wavelength is 730-nanometers.

The light produced by the LED panel can be tweaked using the built-in veg and bloom modes. There are 2 selectable switches, one for the bloom mode, and the other for the veg mode.

When this unit is turned to the veg mode, it draws about 189-199 watts of power depending on the voltage source, while in the bloom mode, it draws about 293-303 watts of power depending on whether a 110-volt or 220-volt power source was used. The veg mode optimizes the germination and seedling development phase of plant development, while the bloom mode optimizing the budding, flowering, and fruiting phases of crop maturation.

MarsHydro Reflector144 is cooled by a high-grade heat sink and 2 high-speed fans. Its lifespan exceeds 50,000hours of continuous usage.

What kind of use MarsHydro Reflector 144 is suitable for?

MarsHydro Reflector 144 is a reliable grow light specially designed to be used by practitioners of hydroponics, greenhouse farming, and indoor gardening.

How MarsHydro Reflector 144 works?

Mars Hydro reflector 144 in use

MarsHydro Reflector144 is a reliable, compactly-designed LED-based grow lamp that uses 144 chips to produce full-band spectral light. The chips are arraigned in two main configurations that provide a 90-degree and 120-degree view angles.

The light emitted has a wavelength range that closely approximates the light wavelengths of sunlight, and this ensures that the crops are cultivated in an enhanced outdoor-like environment, with light fine tuning allowing the blue light to optimize the vegetative stage of crop development, while the red light is given prominence later on during the flowering stage.

This unit comes as a plug-and-use grow light, with its power cable featuring a standard top-plug that can fit in any universal AC-power socket.
