Kessil H80 Tuna Flora Refugium LED Light

Target Algae Growth with the Kessil H80 Tuna Flora Refugium LED Light

The Kessil H80 Tuna Flora Refugium LED Light delivers focused lighting performance for macroalgae like chaetomorpha—without taking up much space. With four spectrum modes and compact design, this light packs more punch than you'd expect from a 4.9-inch disc.

Built for Refugiums — Quiet, Durable, and Tunable

Unlike noisy, oversized lighting setups, the Kessil H80 uses a built-in heat sink to cool silently—no fans, no moving parts. That makes it perfect for humid sump spaces where air circulation is limited.

Key Features:

• Fanless cooling system with integrated heat sink

• Tunable color spectrum optimized for algae growth

• Kessil Logic™ ensures balanced light output

• Dimmable and controller-ready (0–10V and Spectral Controller compatible)

• Daisy-chain capability with Kessil Unit Link cables

• Includes canopy mount for easy setup

Dense Matrix LED: Small Package, Wide Spread

Kessil’s proprietary Dense Matrix LED packs multiple wavelengths into a single chip no bigger than a dime. This technology ensures even light blending, minimizing hot spots while covering a broader footprint than you'd expect.

• Maximum Spread: 20" x 20"

• Optimal Spread: 15" x 15"

• Smooth spectrum blending before the light leaves the lens

For larger refugiums, link multiple units together—no guesswork, just clean light distribution.

Light Modes That Adapt to Your Algae

The H80 Tuna Flora includes four built-in color modes—Grow, Bloom, Red, and Blue. Whether you're running a chaeto reactor or a mangrove grow-out, you'll find a mode that fits your setup.

• Grow Mode: Balanced for general macroalgae

• Bloom Mode: Encourages flowering in aquatic plants

• Red Mode: Strong vegetative light output

• Blue Mode: Ideal for specialized freshwater applications
