- Weighs 7.8 pounds
- 100 pcs 3W Epiled LEDs
- Draws 140W +/-5% at 120V
- Features zener diode technology
- Daisy chain connection
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 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 light is also well-protected against dampness, rust, and corrosion.
This Galaxyhydro 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.
