Orphek Natura iCon: Exceptional PAR Coverage and Light Distribution at Four Different Distances
Discover today how the Natura iCon delivers powerful, consistent illumination across your reef aquarium.
When choosing the best LED lighting system for a reef aquarium, PAR performance is about much more than achieving impressive peak readings.
Also equally important is how effectively light is distributed across the entire aquarium, reaching different areas with consistent intensity and minimizing unnecessary light loss.
A powerful reef LED should not simply concentrate its output directly beneath the fixture.
It should provide effective coverage across the aquarium footprint, allowing corals positioned in different locations to receive the light they need.
The Orphek Natura iCon was engineered with this principle in mind.
To demonstrate its optical performance, we present a complete analysis of its official PAR maps, measured at four different distances: 30 cm (12 in), 60 cm (24 in), 90 cm (35 in), and 120 cm (47 in) from the lighting fixture.
Tested over a 120 × 60 × 60 cm (47 × 24 × 24 in) aquarium, with a water depth of 55 cm (22 in), these measurements reveal how the Natura iCon distributes light across 72 measurement points, demonstrating its combination of intensity, coverage, and optical efficiency.
All measurements were taken on this larger 120 × 60 cm (47 × 24 in) footprint.
Achieving full coverage of the entire grid at 60 cm, 90 cm and 120 cm further demonstrates the Natura iCon’s light distribution performance.
Let’s dive into the results.
1. Understanding the Natura iCon PAR Coverage Test
To evaluate the Natura iCon’s light distribution, PAR measurements were taken across a defined grid covering a 120 × 60 cm aquarium footprint.
The testing conditions were:
- Aquarium dimensions: 120 × 60 × 60 cm
- Water depth: 55 cm
- Measurement grid: 10 × 10 cm cells
- Measurement points: 72 (12 × 6 grid)
- Distances tested: 30 cm, 60 cm, 90 cm, and 120 cm
- Lighting fixture: Orphek Natura iCon, 150 W platform
All readings are expressed in µmol photons m⁻² s⁻¹ (PPFD – Photosynthetic Photon Flux Density).
Each PAR map provides a visual representation of the light distribution across the measurement grid, allowing us to evaluate not only the highest intensity achieved, but also the centre average, overall grid average, and number of illuminated measurement points.
This is important because a single peak PAR reading cannot tell us how effectively a lighting fixture illuminates the entire aquarium.
By examining the complete measurement grid at four different distances, we can better understand the Natura iCon’s coverage capabilities and the flexibility of its optical design.
2. Complete Natura iCon PAR Map Analysis at Four Distances
30 cm (12 inches) from the Light: Powerful Intensity and Wide Distribution
PAR Results:
- Peak PAR: 705
- Centre Average: 380
- Grid Average: 181
- Points Lit: 48 / 72
<PAR MAP – 30 CM>
At 30 cm from the fixture, the Natura iCon demonstrates exceptional light intensity, reaching a peak PAR of 705.
The centre average of 380 and grid average of 181 reveal that its performance extends beyond the highest-output measurement points.
The PAR map shows several high-intensity areas across the central portion of the grid, with readings reaching the 400–700 range, while maintaining light distribution toward the outer measurement positions.
This combination of powerful output and broad distribution makes the Natura iCon particularly interesting for demanding SPS aquariums and reef keepers seeking higher light intensity.
The results demonstrate how the Natura iCon combines concentrated intensity with effective coverage across the tested aquarium footprint.
60 cm (24 inches) from the Light: Excellent Coverage Across All Measurement Points
PAR Results:
- Peak PAR: 216
- Centre Average: 164
- Grid Average: 122
- Points Lit: 72/72
<PAR MAP – 60 CM>
At 60 cm, the Natura iCon continues to demonstrate impressive coverage.
Despite the increased distance, the fixture maintains a peak PAR of 216 and a centre average of 164, with a grid average of 122.
One particularly important result is that all 72 measurement points register PAR.
This demonstrates the fixture’s ability to distribute light across the entire measured aquarium footprint, rather than concentrating its output exclusively in the central area.
For reef keepers, effective coverage means greater flexibility when positioning corals throughout the aquarium, helping to create a more consistently illuminated environment.
90 cm (35 inches) from the Light: Consistent Coverage at Greater Distances
PAR Results:
- Peak PAR: 128
- Centre Average: 90
- Grid Average: 83
- Points Lit: 72/72
<PAR MAP – 90 CM>
At 90 cm, light intensity naturally decreases as the distance from the fixture increases. However, the Natura iCon continues to illuminate all 72 measurement points.
The grid average reaches 83, while the centre average remains at 90.
These results demonstrate that the Natura iCon maintains measurable light distribution throughout the tested aquarium footprint, even at a considerably greater mounting distance.
This flexibility can be valuable in installations where a higher fixture position is preferred or required.
120 cm (47 inches) from the Light: Full Measured Coverage Even at Extreme Distance
PAR Results:
- Peak PAR: 114
- Centre Average: 63
- Grid Average: 70
- Points Lit: 72/72
<PAR MAP – 120 CM>
At 120 cm, the Natura iCon delivers another interesting result.
Conclusions:
Even at this considerable distance (120cm), all 72 measurement points continue to register PAR, with a grid average of 70.
The fact that the entire measured grid remains illuminated demonstrates the effectiveness of the Natura iCon’s optical design in distributing light across the aquarium footprint.
Although the intensity is naturally lower at this distance, the results reveal the fixture’s ability to maintain measurable coverage well beyond conventional mounting distances.
For reef keepers evaluating different installation possibilities, this provides valuable insight into how the Natura iCon performs when positioned higher above the aquarium.
3. Coverage at the Bottom of the Aquarium: Reaching Every Area of Your Reef
One of the most important considerations when evaluating reef aquarium lighting is how effectively light reaches the bottom of the aquarium.
High PAR readings directly beneath a fixture can be impressive, but they do not necessarily indicate how much light reaches the outer areas of the aquarium or the corals positioned closer to the bottom.
This is why complete PAR maps are so valuable.
The Natura iCon’s measurement grids allow us to evaluate light distribution across the aquarium’s 80 × 60 cm footprint, including the bottom measurement area.
At 60 cm, 90 cm, and 120 cm from the fixture, all 72 measurement points register PAR.
This demonstrates that the Natura iCon does not simply concentrate its output in a limited central area. Its optical system distributes light across the measured footprint, reaching the different positions represented in each grid.
For reef keepers, this matters because corals occupy different heights and positions within the aquarium. Effective coverage helps provide greater flexibility when arranging coral colonies and designing the overall reef structure.
The objective is not simply to achieve high PAR beneath the fixture, but to distribute light effectively throughout the aquarium, including its bottom and outer areas.
This is an essential aspect of the Natura iCon’s lighting performance.
4. What Do the Four PAR Maps Reveal About Natura iCon?
Looking at all four PAR maps together provides a more complete understanding of the Natura iCon’s optical performance.
High Peak Intensity
With a peak PAR of 705 at 30 cm, the Natura iCon demonstrates substantial light output for demanding reef aquarium applications.
Strong Centre and Grid Averages
Peak PAR alone does not describe the overall performance of a lighting system.
Centre and grid averages provide additional information about how light is distributed throughout the measured area.
The Natura iCon demonstrates strong central intensity while maintaining measurable illumination across the entire grid.
Complete Measured Coverage
At 60 cm, 90 cm, and 120 cm, all 72 measurement points register PAR.
This is an important indication of the fixture’s ability to distribute light across the entire tested footprint at different mounting distances.
Flexibility in Mounting Distance
The four measurements demonstrate how the Natura iCon performs under different installation conditions.
From close mounting positions that prioritize higher intensity to considerably greater distances that prioritize installation flexibility, its optical system continues to provide measurable light distribution.
Efficient Light Distribution
The combination of high-density dual-chip LEDs, optimized drive current, and precision reflectors is designed to direct light efficiently into the aquarium.
The result is a lighting system engineered to balance intensity, coverage, and electrical efficiency.

Precision 90° Reflectors
The Natura iCon features exclusive 90° deep reflectors engineered to control the direction of light and improve its distribution throughout the aquarium.
Rather than allowing light to disperse unnecessarily outside the aquarium, the reflectors help direct the output toward the areas where it is needed.
This optical design plays an essential role in achieving the coverage demonstrated in the PAR maps.
Optimized Drive Current
LED efficiency is influenced not only by the LEDs themselves but also by how they are operated.
Orphek optimizes the drive current to achieve an effective balance between light output, energy consumption, and heat generation.
