Our Verdicts
EcoTech Radion XR15 G6 Pro LED Reef Light
The Radion XR15 G6 Pro is the most technologically advanced reef light you can buy. Ten independently controllable channels with four UV wavelengths give you unprecedented spectrum customization. If you're already in the EcoTech ecosystem or want the absolute best light science available, this is endgame reef lighting.
Kessil A360X Tuna Blue LED Aquarium Light
The Kessil A360X delivers the most natural-looking light in reef keeping. The shimmer effect from its Dense Matrix LEDs is stunning, and the wide 30x30" spread means fewer fixtures per tank. If you value aesthetics and clean design over granular channel control, the A360X is the premium choice.
