Kessil A160WE Tuna Blue Controllable LED Aquarium Light
The Kessil A160WE Tuna Blue is a 40W controllable LED aquarium light tuned for reef and saltwater systems, ranging from 10,000K to 20,000K across the spectrum knob (Deep Ocean Blue to Sky Blue). Patented Dense Matrix LED technology concentrates multiple LED chips into a single array, delivering deep penetration and shimmer equivalent to a 175W metal halide.
Controllable Reef LED with Daisy-Chain Compatibility for Aquarium Setups
The compact 4” x 2.48” 0.69-lb fixture covers a 24” surface diameter at 12”–24” above the water line and runs on a 100–240V AC input / 19–24V DC output power supply. Two control knobs handle overall intensity and blue/white spectrum balance, while 0–10V external control compatibility and daisy-chain wiring let multiple A160WE units run from a single source.
