Quick Overview

Recommended spread up to 36" x 20"

The Zetlight ZT-6600A 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 groupings helps simulate natural sunlight intense power. We really like the QMaven series of lights from Zetlight for their affordability, ease of mounting, and performance.

How does light affect where a person will sit and not be blinded by the light. This light will be almost 5 ft high and my wife is worried about the light shining in our ears
Question by: Robert Escher on Jun 16, 2016 5:54:00 PM
Hey there!
With the light being 5 feet high there will certainly be some unavoidable light spillage to shine in your eyes. These lights will typically only impact your eyes when sitting next to the tank.

Hi - How do you think 2 of these lights would do for SPS coral in a 6 foot 215 gallon tank? Would love to do the Ecotechs, but feel I would need 3 which would make it very difficult to justify from a financial perspective. Thank you!
Question by: Scott Flinchbaugh on May 11, 2016 9:30:00 PM
Great question!
With the average spread being 36" two of the fixtures would work great over a tank of 72" The spread will be not quite 20" deep for SPS growth though to keep in mind the overall depth the lights can penetrate.

Can this unit be used with Vertex Cerebra
Question by: Jerome Tucker on Jun 18, 2016 9:14:00 AM
Great question!
This will be able to be turned on or off but not controlled.
Answer by: Connor (Admin) on Jun 21, 2016 5:07:00 PM
is this light reef compatible?
Question by: wyman mckinley on Mar 8, 2016 10:59:00 AM
Great question!
This light is designed for coral growth and will work well! It is not reef keeper compatible and currently can run alone or with the apex VDM module and adapter. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 10, 2016 1:51:00 PM
It says the it can be mounted to tanks up to 47" in length. My 75 gallon which appears to be standard size for 75 gallon tanks is 48" in length. Will this light fit using the tank stands?
Question by: Roberto Miller on May 1, 2016 9:20:00 AM
Great question! Unfortunately this fixture will not fit 48" tanks.

Can these be daisy chained to each other to program multiple units to the apex?
Question by: Nick on Jun 20, 2016 1:29:00 PM
great question!
These lights are not able to be daisy chained together for function with the apex. Feel free to let us know if you have any further questions!

Hi. I have gained a lot of info from other questions asked and a few videos. One question I have that I cannot find an answer to is, will this light create a shadow or line in a 65 gallon tank that has center cross bracing? I would like to think that the LED's are spread out enough that this would not happen but am not completely sure. Only other light I am considering is the Kessill A160we but I am a reefer on a budget and any less spending goes a long way. Thanks and happy memorial day weekend to ya!
Question by: Dan on May 30, 2016 1:56:00 PM
Great question!
There will be a slight shadow depending on how high the light is off the tank. This will not be impacting the multi-chip LED and not noticeable in most cases. Feel free to let us know if you have any further questions.
Answer by: Connor (Admin) on Jun 7, 2016 2:00:00 PM
I was confused by the PAR Value diagram. I would like to clarify if these lights would be appropriate for my tank size of 36L x 18W x 25 H. Thank you very much.
Question by: Gerald on May 30, 2016 3:30:00 PM
Great question!
These will work great over a 36 x 1 area. With most Par for high light corals in the center and lower light corals towards the bottom and edges of the tank. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jun 7, 2016 2:26:00 PM
Can you chain two together (for a larger tank) and control with the apex as one unit or will the two units need to be controlled separately?
Question by: Matthew Achimon on Apr 21, 2016 5:51:00 PM
Great question!
Two cannot be controlled as one with the Apex. An individual apex connection will be required for each light.

Full Details

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, their 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 47" and tuck in as tight as 28.3". 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.

  • GREAT LIGHT for 75G REEF By Gary on 5/3/2016

    I want to thank Matt from youtube (Matt's reef tank) for making me known this amazing light. Tank look sharp, Rock wrap with purple algae after 2 months used. Easy set up from Dawn -Sunrise-daytime-sunset-nighttime. Two thumbs up!
  • Great Light for 75G Reef By Mr. Macy on 4/1/2016

    I bought this and cannot say anything negative about it. I have it sitting about 12 inches above the tank and the light is spread evenly across the entire tank. very happy with it. does not get too hot and the fans are very quiet. you can control Whites, Red-Green-Orange, Blues and Violets (UV) individually on each mode. really nice light. don't have an APEX yet.. one 500 dollar purchase at a time..
  • Great Light! By Kristopher on 3/19/2016

    Glad I gave this a try. Great coverage and color, very customization, easy setup. Can't beat the price for what you get. Thought it needed a positive review, should be more out there.
  • Excellent AND Stylish Light!!!! By FISHGEEK on 3/11/2016

    Let me first say that I am not an expert on lights. My friend, who got me into fish in the first place, recommended me into getting Zetlight. He has the lancia models, but I decided to go with the 6600A model because I really love the apex ready. It is a perfect size, quiet, and it includes a controller! The setup was super easy and now my fish looks fantastic. Great product!
