Best lights for the Red Sea MAX Nano G2 Cube
Match the fixture's coverage footprint to your tank's display footprint — a light rated for a 12×12 in area is a poor fit over a 16×16 in tank. Then pick an intensity tier based on your corals: low for soft corals or FOWLR, medium for LPS or mixed reefs, high for SPS. Most nano light manufacturers don't publish PAR, so coverage and intensity tier are the practical sizing handles.
The Red Sea MAX Nano is a 45cm (17.7 in) rimless all-in-one cube with about 16.5 gallons of display water and ~20 gallons total including its rear sump; the current G2 Cube and the popular original / ReefLED-50 versions share the exact same tank body. It ships complete with an integrated light (a WiFi ReefLED G2 60 on current units), a Nano XL / REEF-SPEC skimmer, an ATO-ready sump, and a filter sock, driven by a single Sicce return pump rated about 250 GPH. Red Sea does not publish internal rear-sump dimensions, so the usable skimmer-chamber footprint should be verified before swapping gear.
Ranked for an LPS / mixed-reef setup. For SPS or soft-only goals, use the sizing tool.

FAQ
Why use coverage footprint and intensity tier instead of PAR?
Most nano fixture manufacturers don't publish PAR data, so PAR-based comparisons aren't possible across the market. Coverage footprint and intensity tier give you a consistent, actionable way to match a light to your tank size and coral type without needing a PAR meter.
What intensity tier do I need for a mixed LPS reef?
Choose a medium-intensity fixture for a mixed LPS or mixed reef tank. Low-intensity lights are sufficient for soft corals and FOWLR setups, while high-intensity fixtures are needed only if you plan to keep demanding SPS corals.
Can I use a light rated for a larger footprint than my tank?
Yes, but it introduces more risk than benefit on a nano. You may end up with excess intensity at the center and uneven coverage, and you'll pay for output you don't need. Matching footprint closely is the better approach.
