Gravity22 2x2 Module 60 Watt 200x200x10mm
Gravity22 2x2 Module 60 Watt 200x200x10mm
Four clusters, square beam geometry. The GRAVITY 22 covers mixed reef setups as confidently as SPS-dominated ones. With 60 watts and a full 5-channel spectrum, it sets standards in the mid-range segment.

5-Channel Spectrum
Dynamic Power Control (DPC) — all 5 channels dimmable independently. System power remains constant at 60 W, regardless of the spectrum mix.
| Channel | Wavelength | Note |
|---|---|---|
| CH 1 · White + UV-A | 6,500 K + 390 nm | CRI 97 |
| CH 2 · Royal Blue | 460 nm + 440 nm | 99.3 % purity |
| CH 3 · Actinic | 420 nm + 400 nm | 99.6 % purity |
| CH 4 · Pink | ~559 nm | – |
| CH 5 · Cyan | 480 nm | 89.5 % purity |
PAR · PUR · LUX
PPF (µmol/s) is the total luminous flux of the fixture — photons per second, regardless of distance or area. High PPF does not automatically mean high PAR in the tank.
PAR (µmol/m²/s) is the area measurement at a tank position. PAR decreases with depth. The LiST Tool calculates the optimal configuration.
PUR weights PAR according to the absorption curve of zooxanthellae. Blue 430–480 nm is weighted more strongly — where corals absorb most efficiently.
LUX measures brightness for the human eye — biologically irrelevant for corals, but useful for visual tank assessment.
