PARwise Pro
End the guesswork in aquarium and horticulture lighting.
PARwise PRO is our top‑of‑the‑range meter that answers the big questions: intensity, spectrum, and photoperiod. With distinct calibrations for air, freshwater, and saltwater — and now fully submersible design — it ensures your organisms get the light they truly need, measured exactly where they live.
Smart Technology — cPUR, YPF, Pigment analyzer, CRI and CQS
Measure What Organisms Actually Userr
- cPUR: A breakthrough metric that combines intensity and spectrum into one simple, coral‑relevant value.
- YPF: The plant equivalent, ensuring aquarists and horticulturists alike can optimize growth.
- Pigment analyzer: Detect pigment absorption peaks to reveal biological response and match lighting to organism needs.
- CRI (Color Rendering Index): Quantifies how accurately a light source renders colors versus a natural reference; essential for evaluating coral coloration, plant appearance, and true-to-life visual assessment.
- CQS (Color Quality Scale): A modern complement to CRI that better accounts for saturated colors and human visual preference, helping you compare fixtures beyond simple PAR and spectrum.
This suite turns PARwise PRO into a biological and visual insight tool, making spectrum decisions both growth-accurate and color-faithful.
Expanded Spectral Range
From UV to IR — Nothing Escapes Detection
- Detects UV‑A and NUV wavelengths down to 350nm.
- Covers a wide spectral range from 380nm to 1100nm.
- Distinct calibrations for Air, Freshwater, and Saltwater.
- Identifies wasted energy in the IR range, helping you fine‑tune efficiency.
This means you see the full picture of your lighting setup, not just part of it.
Empowering Growth & Community
Accurate Data, Confident Decisions Perfect growth requires the right wavelengths, the right intensity, and the right duration. PARwise PRO empowers you to:
- Place corals correctly every time you buy new stock.
- Share and compare lighting setups with the reefing community.
- Achieve healthier growth rates across aquatic and terrestrial organisms.
One saved coral makes PARwise PRO worth it — and it will save many more.
