LED composition and spectra
As mentioned earlier, Orphek Natura iCon displays 13 different colors of LEDs, with UV (390 nm), violet (400-415 nm), blues (420, 430, 450, 460 nm), cyan (470, 480 nm), 18 000 Kelvin white, amber (590 nm), red (670 nm) and infrared (740 nm).
Below is the breakdown of each color and their arrangement into six channels :
Here are the measured spectra by us. First, we present the 100% power spectrum. We notice a neat dominance in the 400-480 nm range, with smaller spikes corresponding to different LED colors.
Below, the individual channel spectra (click to enlarge):
Here, we overlay the whole power Natura iCon spectrum to major coral pigments absorption spectra :
We recognize Orphek’s significant effort to establish a correlation between LED emissions and pigment absorption in this model. This thoughtful design allows for the creation of a spectrum that is not only visually appealing to hobbyists but also biologically beneficial for corals.
Importantly, we have been using this spectrum for several months, and we (and most importantly, the corals) are pleased with the results, showing nice tissue extension and coloration. For instance, some LPS corals, such as chalices and Pectinia space invader, have begun to enhance their orange pigments.
It is obtained with this setup: Channel 1 at 5%, Channel 3 at 45 %, Channel 3 at 100%, Channel 4 at 100%, Channel 5 at 80% and Channel 6 at 20%.
Intensity measurements: PAR / PFFD
After assessing the light spectrum, we proceeded to measure the intensity of light that is beneficial for coral growth, specifically using PAR (more accurately referred to as PPFD). The intensity is measured in micro-moles of photons per square meter per second (µmol photons/m²/sec).
Measurement Conditions: Intensity was recorded with all channels set to 100% power (shown in the first three plots) as well as under a program we typically use for a mixed reef tank (shown in the last three plots).
Depth Measurements: Measurements were conducted at depths of 20, 40, and 60 cm below the Orphek Natura iCon light fixture.
Measurement Area: An area of 80 x 60 cm was used for the intensity measurements.
Measurement Environment: Measurements were taken in open air, as the light reflection on the water surface can vary significantly depending on water flow.
Results:
We observed high PAR values. When all channels were set to 100%, we measured values reaching up to 1300 µmol photons/m²/sec at a depth of 20 cm. At 40 cm depth, PAR values exceeded 400 µmol photons/m²/sec in the center of the measurement area. At 60 cm depth, the values ranged between 200 and 270 µmol photons/m²/sec in the same central area.
As we present the PAR measurement values from our testing tank, it is important to note that this tank is a mixed reef system housing a variety of corals. This includes SPS varieties such as Acropora, Stylophora, and Montipora, LPS varieties like Euphyllia, Blastomussa, Scolymia/Homophyllia, Australlophyllia, Pectinia, and Goniopora, as well as soft corals including Zoanthus, Rhodactis, and Clavularia. The selected spectrum provides an excellent balance between blue wavelengths that enhance coral coloration and fluorescence, along with white light that maintains a natural appearance during the daytime.
To increase light intensity, you can adjust the power levels of channels 1 and 2. Channel 1 produces a warmer light with yellow-orange tones, while channel 2 provides a cooler cyan hue. Even with channel 1 set at just 5% and channel 2 at 45%, we are still achieving commendable PAR values in this setup.
Heatsink
The heatsink is a vital component in the design of light fixtures. LEDs generate heat as a byproduct of their electrical properties, and it is essential for this heat to be dissipated into the surrounding air to ensure the longevity of the LEDs.
In this setup, two fans are positioned to actively diffuse heat away from the LED board. However, it is important to note that these fans can be audible in a living or dining room environment. We conducted noise measurements using a smartphone app, taken from a distance of 1 meter from the tank:
Ambient noise with the Orphek Natura iCon OFF: 33.4 dB
Noise level with the Orphek running at full power: 39.3 dB
Noise level with the Orphek running at full power in quiet mode: 37.1 dB
We also took thermal measurements using a thermal camera. The room temperature was recorded at 21°C, while the heatsink exhibited an average temperature of 27°C, as indicated on the app. This temperature corresponds to the mean temperature of the heatsink side.
Electrical Features and Additional Characteristics
Here are some additional details about the Orphek Natura iCon LED fixture:
- Dimensions (L x W x H): 367 mm x 210 mm x 48 mm
- Weight: 3.2 kg
- Maximum Rated Consumption (provided by the brand): 150 W
We also assessed several electrical parameters with all channels set to 100% power. The power factor measured at 0.96, indicating that the fixture effectively utilizes 96% of the power it consumes, showcasing its energy efficiency.
