Red Sea ReefLED 90 fit check

Quick answer

Red Sea ReefLED 90 is a 90W reef light listing about 24x24 in of coverage and roughly 220 PAR at 18 inches. That clears ReefCrafter's PAR targets for soft coral, LPS, and mixed reef tanks, but not SPS. Tanks wider or longer than 24x24 in need a second fixture or a mounting plan that spreads light.

Who it is for

Good fit for

  • ✓ 30-90 gallon systems, per the catalog fit range.
  • ✓ Soft coral (50-150 PAR), LPS (100-200 PAR), and mixed reef (150-250 PAR) goals at about 18 in depth.

Not a fit for

  • ✕ Tanks under about 30 gallons; it is sized above them.
  • ✕ Systems over about 90 gallons without adding capacity elsewhere.
  • ✕ SPS (250-350 PAR) goals from a single fixture.
  • ✕ Footprints larger than about 24x24 in from one unit.

Compatibility math

Coverage and PAR

fixture coverage >= tank footprint and PAR >= coral target

Example: A common 75g footprint is 864 sq in; this fixture lists about 576 sq in and 220 PAR at 18 in.

ReefCrafter checks spread and intensity separately because a bright hotspot still leaves dim edges.

Risk notes

  • The common mistake is buying a light that grows soft corals now but cannot support the mixed or SPS reef the keeper already wants.
  • Price is marked as estimated, so verify current vendor pricing before treating the budget as final.
  • Large or SPS-heavy tanks may need multiple fixtures even when one light technically fits the gallons.

Professional fit context

  • Match coverage width, coverage length, PAR at depth, mounting plan, and fixture count.
  • Red Sea ReefLED 90 fits roughly 30-90 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.
  • Treat the displayed price as a budget placeholder until a reviewed vendor page confirms current pricing.

Questions

Can the Red Sea ReefLED 90 grow SPS corals?

Not from one fixture at 18 inches. It lists about 220 PAR, below ReefCrafter's SPS target of 250-350 PAR. It meets the soft coral, LPS, and mixed reef targets.

How large a tank does one Red Sea ReefLED 90 cover?

The listing gives about 24x24 inches of coverage. A tank footprint larger than that needs another fixture or a raised, spread mounting plan to avoid dim edges.

What tank size is the Red Sea ReefLED 90 for?

ReefCrafter's catalog fit range for it is 30-90 gallon systems. Confirm that against your final display volume, sump volume, and livestock plan rather than the box label alone.

What should I compare the Red Sea ReefLED 90 against?

Nicrew HyperReef 100 Gen 2 LED Reef Light (200 PAR at 18 in vs 220: less intensity, suited to lower-light corals); Orphek Atlantik iCon Compact (250 PAR at 18 in vs 220: more intensity for higher-light corals); Kessil A360X Controllable LED Tuna Blue (280 PAR at 18 in vs 220: more intensity for higher-light corals).
