Product Review

Design and Durability

It features a heavy-duty design that is made of fire-resistant housing. At the back of the unit, you have an on/off switch, power outlet, daisy connection outlet, and three bass cooling fans.

The premium design features upgraded heat sinks, which in combination with the high speed bass fans, they deliver superior cooling system, heat dissipation and optimal working temperatures at all time.

The professional design also adopts a hundred pieces of high-intensity Epiled LEDs rated at 3W. These LEDs are the most effective because they do not heat up easily like the 5W and 10W LEDs.

The zener diode technology used protects the individual LEDs. A burn out LED will not affect the performance of the rest.

Apart from having excellent heat insulation, the shell of this indoor plant grow light is also well-protected against dampness, rust, and corrosion.

This Galaxyhydro LED design also features dimmer technology. It has a dimmer located at the back of the unit, which allows you to conveniently adjust the brightness from 0 to 100 percent.

The dimmable light setting is a very resourceful feature because it allows you to control the brightness at different growth stages of your plants. You can optimize for veg and flowering stage when you need to.
