Best saltwater reef aquarium lights
Researched by Deal.ai's shopping agent across stores on November 2, 2026. Prices below are today's.
Top pick: EcoTech Marine Radion XR15 G6 Pro — the safest bet for coral growth. It's a proven full-spectrum fixture with strong PAR and app control, so you can tune a schedule for SPS and LPS alike, and it's rated well by owners.
Who the others suit:
- AquaIllumination Hydra Edge 68HD — a wide, even spread for tanks where you want one fixture over a longer footprint.
- Red Sea ReefLED G2 115 — simple, plug-and-play spectrum for mixed reefs and beginners.
- ATI Straton X — fanless and ultra-slim, for a clean look over a shallow tank.
- AI Prime 16HD — small tanks and nanos; add a second for bigger footprints.
- Fluval Reef 4.0 — budget-friendly starter lighting for softies and LPS.
Match wattage and spread to your tank length, and expect SPS to want more fixtures than LPS.
