Kessil is a fiber optic and specialty lighting company based in San Francisco. The company invested 30 million dollars in R&D and created their unique style of LED aquarium lighting fixtures.

Kessil created their signature densely packed LED arrays, combined with a special reflector. The outcome was a powerful, compact and efficient pendant LED fixture. Other technological advancements include quiet heat dissipation without noisy fans and simple two-knob color control. Kessil pendants can also be controlled by their own Spectral Controller or a third-party aquarium controller, like the Neptune Systems Apex.

In 2015, the company leveraged the technology of their award-winning pendant lights and expanded it into a larger 185-watt panel platform, the Kessil AP700. Dialing in the perfect color, intensity, and scheduling can be accomplished directly on the fixture or wirelessly through the Kessil Wi-Fi Controller app for iOS and Android devices.

Kessil LED lights are renowned for their natural shimmer effect which many hobbyists compare to metal halide lighting. High-quality components, simple controls and rock-solid mounting systems make Kessil a leader in aquarium lighting.
