The Zetlight ZT-6500A LED lighting fixture is a slim, sleek, and innovative new light that can be fully controlled by a Neptune Apex controller. Top of the line Bridgelux LEDs are strategically placed throughout the fixture, and the 40w big power dense LED group helps simulate natural sunlight intense power. We really like the QMaven series of lights from Zetlight for their affordability, ease of mounting, and performance.


Ultra-Thin Design

The Zetlight ZT lights are made out of aluminum for a super light and thin design that is attractive to look at. With the moonlight strips even when the main light is off it gives off a beautiful blue accent that will act as a moonlight for your tank.


Smart Fan Technology

With Smart Fan technology the fan will start to turn on as the lights temperature increases and turn off as it decreases keeping your light running at peak performance for a lifetime. The Fan will direct cool air over the aluminum housing while the air intake shroud keeps saltwater and dust out of the cooling fins.


Superior Control

Controlling the Zetlight ZT is very simple with the included on-board interface and infrared remote control, there are well over 999,999 different configurations. If you have a Neptune Apex controller, it is very simple to connect the light to a serial port on a VDM module and program the light.


Flexible Mounting Solutions

Included are easy to install mounting legs that can easily mount onto the rim of any tank up to 1.2" thick. The legs can extend to fit tanks as long as 27" and tuck in as tight as 18". A hanging kit can also be used to suspend the fixture from ceilings, wall brackets or inside of a hood. If you are going to mount the light within a canopy we do recommend keeping a few inches between the fan and the top of the canopy to allow proper airflow around the fixture.

Product Questions

how high can i hang these? i have 3 of them over a 90 gallon
Question by: jeffrey burge on Jan 8, 2017, 11:50 AM
Great question! Typically, most lighting is hung between 7"-10" above the water surface. This will allow for proper spread as well as best concentration of even PAR. :-)

I will be installing these on a 6 foot long 210 gallon aquarium. How many fixtures will I need? I am thinking 3 and mount then front to back along the length of the aquarium.

Great question!
Ideally you will want 3 fixtures over your tank. Feel free to let us know if you have any further questions!
