Best lights for the JBJ RF-45 Rimless Flat Panel
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 JBJ RF-45 Rimless Flat Panel is a 45-gallon (170L) all-in-one with a 26.5 × 22 in footprint and 19 in height, in 10mm low-iron flat-panel glass. It is sold as a tank-only AIO with no integrated lighting, so a separate reef light is required. The integrated rear sump uses a baffled column system with designated heater and skimmer chambers and 4-inch micron socks, and ships with two FP-1000 return pumps rated 264 GPH each. JBJ does not publish rear-chamber internal dimensions, so chamber fit should be verified by direct measurement before choosing a skimmer.

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.
