See how Natura iCon MAX distributes light across a 120 × 60 cm (47 × 24 in) test footprint, with PAR maps at four distances and results from 72 measurement points.
More Power for Your Larger Reef
For reef keepers planning a larger aquarium or a more demanding lighting setup, the Orphek Natura iCon MAX brings together a 280–290 W platform, 156 mixed-color dual-chip LEDs, and six independently controlled channels.
Its PAR maps tell the story beyond the central hotspot: a peak reading of 966 at 30 cm (12 in) from the fixture, plus measurable illumination at all 72 test points at distances of 60 cm (24 in), 90 cm (35 in), and 120 cm (47 in), across a 120 × 60 cm (47 × 24 in) test footprint.
Explore the results below to see how MAX combines intensity, coverage, and intelligent control for larger reef systems.
When choosing reef aquarium lighting, peak PAR tells only part of the story. Equally important is how light reaches different positions across the aquarium. Building on the Natura iCon platform, MAX scales up the LED configuration and power for larger, more demanding setups.
Understanding the Natura iCon MAX PAR Coverage Test
The maps in this article document the following test setup:
- Aquarium dimensions: 120 × 60 × 60 cm (47 × 24 × 24 in)
- Water depth: 55 cm (22 in)
- Measurement grid: 10 × 10 cm (4 × 4 in) cells
- Measurement points: 72, arranged in a 12 × 6 grid
- Distances from the fixture: 30 cm (12 in), 60 cm (24 in), 90 cm (35 in), and 120 cm (47 in)
- Lighting fixture: Orphek Natura iCon MAX, approximately 290 W platform
Measurement distance is not mounting height. The distances in these maps are measured from the fixture to the measurement plane. The recommended installation height is 20 cm (8 in) above the water surface.
All PAR readings are expressed as PPFD in µmol photons m⁻² s⁻¹. Results apply to the test setup shown; meter, aquarium dimensions, aquascape, and measurement method can affect readings. These results should not be treated as a controlled comparison with measurements from a different setup.
Each map shows peak PAR, centre average, grid average, and the number of points registering light. Together, these describe measured distribution more fully than a peak reading alone.
Natura iCon MAX PAR Results at a Glance
At 30 cm (12 in), 68 of 72 points register light. At 60 cm (24 in), 90 cm (35 in), and 120 cm (47 in), all 72 points register PAR. Measurable coverage does not mean identical intensity at every point.
Complete PAR Map Analysis at Four Distances
30 cm (12 in): High Peak Intensity
Peak PAR: 966 · Centre average: 681 · Grid average: 351 · Points lit: 68 / 72
At 30 cm (12 in) from the fixture, Natura iCon MAX reaches its highest peak reading in this four-distance test. The centre average of 681 and grid average of 351 show performance beyond the single brightest point, with strong readings across the central zones.
The map shows multiple high-intensity areas, including central readings above 500 and up to 966. Four corner positions do not register light at this measurement distance, illustrating why the complete grid matters alongside peak output.
For reef keepers evaluating a higher-output lighting system for a larger aquarium, these readings provide a useful reference. Final intensity settings and coral placement should reflect the needs of the individual reef.
60 cm (24 in): Light Registered at All 72 Points
Peak PAR: 515 · Centre average: 420 · Grid average: 324 · Points lit: 72 / 72
At a measurement distance of 60 cm (24 in), MAX combines a peak PAR of 515 with a centre average of 420 and a grid average of 324.
Importantly, all 72 measurement points register light. This shows illumination across the full tested footprint rather than output confined to the central hotspot. The map helps reef keepers assess the differences between central and outer positions when planning a lighting layout.
90 cm (35 in): Broad Measured Coverage at Greater Distance
Peak PAR: 354 · Centre average: 213 · Grid average: 230 · Points lit: 72 / 72
At 90 cm (35 in) from the fixture, all 72 points continue to register PAR. The grid average is 230, with a peak of 354 and a centre average of 213.
This map adds another view of MAX's optical distribution, showing how readings change across the footprint as measurement distance increases. It is a test result, not a recommendation to mount the fixture 90 cm above the water.
120 cm (47 in): Full Grid Registration at the Longest Test Distance
Peak PAR: 220 · Centre average: 124 · Grid average: 148 · Points lit: 72 / 72
Even at the longest measurement distance in this test, all 72 points register light. Peak PAR reaches 220, with a centre average of 124 and a grid average of 148.
Although intensity is lower than at shorter distances, the map documents measurable illumination across the full tested grid. Use the individual readings, not coverage alone, when considering the requirements of specific corals.
Coverage at the Bottom of the Aquarium: Reaching Beyond the Central Hotspot
One of the most important considerations when choosing reef aquarium lighting is how effectively light reaches the bottom of the tank. A high reading directly beneath the fixture tells only part of the story: corals positioned lower in the aquarium and toward its outer areas also matter.
This is why complete PAR maps are so valuable. The Natura iCon MAX maps document light distribution across a 120 × 60 cm (47 × 24 in) footprint, using a test aquarium with a water depth of 55 cm (22 in). Looking across the grid, rather than only at its brightest point, provides a more useful reference when planning illumination for the lower reef and outer areas.
At fixture-to-measurement distances of 60 cm (24 in), 90 cm (35 in), and 120 cm (47 in), all 72 measurement points register PAR, with grid averages of 324, 230, and 148 respectively. These results demonstrate measurable light across the full tested footprint, not just a limited central area.
For reef keepers, the practical goal is not simply high PAR beneath the light, but a layout that considers corals throughout the reef, including those near the bottom and toward the edges. The individual map readings help evaluate that distribution alongside the aquarium's dimensions, rockwork, and each coral's lighting requirements.
Fixture-to-measurement distances are not aquarium depths or recommended mounting heights. The recommended mounting height remains 20 cm (8 in) above the water surface; actual bottom readings will depend on the installation and aquascape.
