EcoTech Marine Radion XR15 G6 Pro
50 LEDs across 11 channels · 105W · Mobius app, Apex-compatible via MXM module · 82% (11 reviews, BRS) · $529.99
Pros
- Owners describe coverage evenness as "crazy with no hot spots" across the tank, per a Reef2Reef PAR-mapping thread
- Widest channel count here (11), giving the most spectrum control of the three picks
Cons
- A buyer of the Blue-only variant (not this Pro/RGB unit) reported real regret over PAR that felt "barely adequate for mixed reef" without add-on lenses, per a Reef2Reef thread. Worth knowing since it's the same fixture family, though not this exact SKU
Kessil A360X Tuna Blue
90W, deep-ocean-blue-to-sky-blue + RGB spectrum · 24-30in coverage · K-Link daisy-chain, no native Apex support · 84% (44 reviews, BRS) · $661.99 (light + controller + mount bundle)
Pros
- Highest buyer rating of the three picks, and daisy-chains up to 32 units on one K-Link network for larger systems
Cons
- Scheduling requires a separate WiFi Dongle or Spectral Controller X purchase, and it's US 110V only, per BRS's own product page
- No native Neptune Apex integration, unlike the Radion
Fluval Marine 3.0 (Best Budget)
36-46W, 7 LED bands · IP67, FluvalSmart Bluetooth app · 4.4/5 (179 reviews, Amazon) · $219.99
Pros
- A verified buyer called the "24 hour loop cycle amazing" with extendable legs that "work perfectly," per an Amazon verified review
Cons
- A verified buyer specifically flagged it as "not enough PAR power and insufficient spectrum for corals," per an Amazon verified review. Treat this as a soft-coral/nano-reef light, not an SPS light
