Kessil`s unique LED array platform packs high power and deep penetration into a sleek, compact fixture, with an innovative heat management system that enhances efficiency and longevity. Its unrivaled optics meticulously create smooth color mixing over a large coverage area. The Kessil LED`s advanced controllability allows multiple fixtures to be adjusted as a group, when linked together through the 0-10V input and output.

Superior Illumination

The H160 Tuna Flora features four efficient spectrums - BLUE, GROW, BLOOM, RED - in one single fixture. The light is perfectly blended, with wavelengths including true UV and Infrared (ranging from 380-780 nm), enhancing photosynthetic efficiency, maximizing its effectiveness through all phases of plant cultivation.

  • UV & FR - The H160 uses true UV-A and far red LED chips which promote algae/plant health and growth.
  • Blue - The BLUE spectrum quickly develops the frame of a plant during every stage by promoting stem extension.
  • Grow - The GROW spectrum is designed to produce all-around vegetative growth throughout the life cycles of various plants.
  • Bloom - The BLOOM spectrum boosts yield by encouraging plentiful flowering during the plants` crucial reproductive stage.
  • Red - The RED spectrum is designed for tissue culture and cloning by producing maximum root growth during the plant`s whole life. During the finishing stage, the RED spectrum also increases the plants` productivity and the quality of the harvest.


  • Adjustable - Switch the spectrum depending on the phase of the plant growth.
  • Heat Management - Innovative heat management system enhances efficiency and longevity.
  • Dense Matrix LED - The unique, efficient Dense Matrix LED array is built in-house at the Kessil facility producing a concentrated single point source densely packed with high-powered LED array that emits more and better light than competing fixtures.
  • Efficiency - The H160 design uses a unique fanless and slim housing with its compact Dense Matrix array with the most photon energy output per watt than any other Kessil fixture.


The H160 can be manually controlled, and is also compatible with 0 ~10V external controllers. Daisy-chain multiple lights for seamless control from a single source.

  • Manual Mode - This mode allows the user to immediately tune the light for customization, individually controlling the spectrum and intensity for ideal settings.
  • Quick Set - With the H-Series Spectral Controller, the quick set mode allows users to create a repeating 24 hour schedule by programming 6 points throughout the day with customized spectrums and intensity.
  • Auto Mode - This mode is designed to simplify the growing process of various types of plants, and can mimic entire seasons with adjustable critical day length.

When you connect Apex Ready certified products to your Apex System, many new options will unfold. How about having your LED lights dim or change color temperature at the touch of your iPad? How about programming your Tunze or VorTech pumps for some serious wave action? That’s what you get when you pair up the Apex System and an Apex Ready certified product.

Does it run hot? Can it sit on top of a 5 gallon bucket with lid? I will drill a hole for the light.
Asked : Sep 28, 2019
By : NitrateKilla, California
I would not reccomend running this on top of a five gallon bucket as the light can get quite warm especially if there is not adequate air flow where it is located.
Answered : Oct 02, 2019
Would this be sufficient lighting for the Nuvo Innovative 40 Gallon with fish and corals?
Asked : Oct 20, 2018
Hi Monica, This light is intended for a planted aquarium. It has the spectrum needed for plant growth, it will not be the right light for corals.

Solid Fuge Light
Easy to use, strong performance
Form factor not the best for applications where height is limited
Works very well. I have it on a reverse light cycle over my fuge in the sump. It's great to have the ability to increase/decrease the intensity to your needs. I have it on a timer and just keep it on the Grow spectrum at about 70% intensity.
