Best lights for the Coralife BioCube 16 (LED)
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 Coralife BioCube 16 is a ~16-gallon all-in-one nano on a compact 15 × 16.75 in footprint, and it ships as a kit with an integrated LED hood (white, blue Moon Glow, and color channels on a 24-hour timer), so no separate light is needed. Filtration runs through a built-in rear chamber whose usable space is tight: the inTank media basket that fills chamber 2 measures about 4.1 in wide × 2.2 in front-to-back × 12.75 in tall, and that ~2.2 in depth is the main constraint for fitting a skimmer or upgraded gear (third-party fitment figures, not factory specs). The stock return is the Coralife S-700 rated 185 GPH.
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.
