Our Amazonas line is the perfect solution for big tanks and humid environments

Orphek for years now has been offering solutions for Oceanariums; Public Aquariums, research aquariums and marine projects. You will also see Orphek in public venues displaying aquariums, such as palaces, hospitals, hotels & shopping malls.

Orphek has been helping them to create a more natural, more easy-to-adapt and healthier environment to any kind of installation and animals and also has been helping them to develop and to explore the beauty that a proper atmosphere can bring to the exhibition.

Mostly, what moves and motivates us to develop such solutions is the fact that Orphek understands that most people do not live near the sea, nor has the possibility or means of learning how to scuba dive. We are aware that the life below the ocean surface and in deep water is beyond our reach as beings that need air to breath. Fortunately it is not impossible and these public venues are there to offer us these experiences!

How rich and close to reality these experiences will be depends fully on how the aquarium developing team and biologists will treat nature as art in the context of display.

• 

Understanding each peculiarity of these habitats, ORPHEK LED LIGHTING has been giving consulting and support to make the correct choice of lightening, installation, and spectrum that will make all the difference for both visitors and species.

Our expertise and our products have been showcased in many important projects world wide and now we are proud to announce that our solutions are upgraded to IP67 certification!

For these venues this is a groundbreaking technology since they face many challenges from financial (they are on a budget) to maintenance of these lights.

Tested for product quality and performance issues means that Orphek has reduced warranty issues and is now providing EXCELLENCE by improving product reliability.

Implementing IP67 testing means that our solutions were tested for:

• Water ingress contamination (waterproof)
• Dust ingress and solid parts contamination
• Fluid ingress contamination

A complete review with PAR Measurements

Danireef blog is the greatest Italian source for reefers in Europe and for our surprise and excitement has published recently a complete review of our lights, offering a lot of technical information about our product and what is really interesting is to check out the extensive PAR measurements results and the comparative tables displaying other brands.

“The Orphek Atlantik V4 is a very solid ceiling light, that is characterized by the use of led of 5 watt but is steered by less than 3, and a big acrylic sheet that divides the led and the aquarium. Thanks to the fact that they are steered by low current the LED will last longer. The ceiling light can be compared to a diffused ceiling light, following the example of the Philips Coralcare (test) and the GNC Bluray (article). Differently from these ceiling lights, the use of little powerful led gives to the Atlantik the possibility to have little reflection…We really appreciated the possibility to have a cooling vent on the side grill that sucks the air and blows it upside, avoiding to put in the ceiling light air with moisture coming from the aquarium, like other ceiling lights that suck the air from below the ceiling light itself…The design in fact, is extremely functional, we have already talked about the vents, but the construction is voted to simplicity and modularity…”

According to Danireef, among the various LED pendant lights in the market today, Orphek is offering a better LED reef light solution for suspended on ceiling layouts being extremely functional and flexible.

They go on giving details about our driver and app which you can fully read in their website (to read all about their technical review of our product go to page 1 of the review by clicking HERE)

Let’s jump to PAR results because this is what we think you all are interested in knowing!

“Orphek Atlantik V4 – our measurements
We found something very interesting when we measured also the PAR, expressed in PFFD that is photosynthetic photon flux density in μmol m-2 s-1 through the best device on the market, the Quantum Meter MQ-510 di Apogee. It is calibrated in order to work under water, then if used in air the measured value has to be divided by 1,32, that’s the diving factor. When we did our test it wasn’t under water, so we had to make the conversion…We did 5 measurements, all at the center of the ceiling light, 1 for each channel at their maximum. In uniformity with the other measurements we’ve done, and most of all for the ones we’ve going to do, we held the probe 20 cm from the ceiling light. We also had measured, as usual, the absorbed power…The total consumption of the ceiling light at its power maximum it was of 226 watt as you can see from the picture…The Cos(fi) has an enviable value of 0,97…Now we can see the 4 channels, individually taken. We alternated the channels in turn, leaving just one on at the 100% by one, then we measured the values.”

CHANNEL 1

Channel 1 offered a set of 5.000° Kelvin and 20.000° Kelvin, green and cyan.

• 

• 

That is a value of 808/1,32=612 μmol m-2 s-1 and a consumption of 72 watt.

CHANNEL 2

Channel 2 shows a complete blue spectrum that includes 430nm, 440nm, 450nm/460nm and 470 nm.

• 

• 

That is a value of 906/1,32=686 μmol m-2 s-1 and a consumption of 84 watt.

CHANNEL 3

It’s the channel where UV and UVb are isolated, 380 nm, 410 nm and 420 nm.

• 

• 

That is a value of 254/1,32=192 μmol m-2 s-1 and a consumption of 43 watt.

CHANNEL 4

The channel 4 is where you will find the two infrared leds.

• 

• 

That is the 353/1,32=267 μmol m-2 s-1 and a consumption of 42 watt.

Summing up the obtained values of the Orphek Atlantik V4 Gen2:

Channel	Gradation	PAR	Consumption	PAR per watt
Channel 1	Green Cyan	612	72 w	8,5
Channel 2	Blue	686	84 w	8,16
Channel 3	UV	192	43 w	4,47
Channel 4	Blue, red and infrared	267	42 w	6,36
All the Channels	1.515	226 w	6,7

Conclusion by Danireef:

“It’s easy to notice from the chart that the major contribution of the PAR are given by the channels green and cyan and the blue channel. The other two channels affect between the half and two-thirds of the measurement.The incredible thing, beyond the excellent measurements, is great uniformity center-edges. We played a little with our quantum meter and we found pretty much identical values on almost the entire area covered by the ceiling light, as if it was a distribution of a neon T5. Very impressive values.”

COMPARING ORPHEK V4 GEN 2 TO OTHERS

After taking PAR measures of our channels Danireef compared ours results with other fixtures sold in the market:

“Recently, we begin to use the new Quantum Meter MQ-510 di Apogee. So the data in comparison between ceiling lights aren’t totally comparable because we were used to use the probe Seneye. Moreover, we have to consider the Orphek with ceiling lights of diffused light like the Philips CoralCare (test), the GNC 466 (italian review) and partially the Maxspect Ethereal. The Philips registered 1.496 PAR, the GNC 696 PAR while the Ethereal 689 PAR… Remember that we did the PAR measurements from 20 cm in air…So, seen the devices, the Orphek Atlantik V4 registers the highest value ever seen in our hands. The ceiling lights, compared to the Philips, are slightly penalized only for their pretty high price. But often the ceiling lights can be found on sale about 8/900 euro, making the cost per watt much more appealing…The values in comparison with the data got by the Seneye may not be too truthful, because they’ve been done with two different devices, one of which is professional. We think that the optimal coverage for SPS corals strongly demanding, it’s an area of 70×50 cm.

Ceiling light	PAR	Watt	Price	PAR/watt	euro per watt
GNC 466	696 (Seneye)	120	1.400 euro	5,8 diffused	11,7
Orphek Atlantik V4	1.515 (Apogee)	226	1.099 euro	6,7 diffused	4,9
Philips CoralCare	1.496 (Seneye)	190	749 euro	7,8 diffused	3,9
Maxspect Ethereal	689 (Seneye)	130	500 euro	5,3 semi diffused	3,8
Led bar Askoll Pure Marine	237 (Apogee)	28	n.d.	8,4
Zetlight UFO ZE-8000	791 (Seneye)	91,5	500 euro	8,6 cluster	5,5
Aqamai LRM	1.088 (Seneye)	87,5	465 euro	12,4 double cluster	5,2

The absorbed power we’ve seen is of 226 watt, then in a relationship cost/watt of about 4,9 euro for each watt. We can make a comparison with the other ceiling lights that we had in our hands is enough to look at the chart below:

Ceiling light	Price	Consumption	Relationship euro per watt
Philips Coralcare	749 euro	190 watt	3,9 euro per watt	Test
Maxspect Ethereal	500 euro	126 watt	4,0 euro per watt	Test (italian page)
Radion XR30w G2 PRO	790 euro	170 watt	4,7 euro per watt	Italian review
Radion XR30w G4 PRO	915 euro	190 watt	4,8 euro per watt	Italian article
OceanLed Sunrise 600	870 euro	180 watt	4,8 euro per watt	Test (italian page)
Orphek Atlantik V4	1099 euro	226 watt	4,9 euro per watt
Radion XR30w G2	690 euro	140 watt	4,9 euro per watt	Italian review
Radion XR30w G4	760 euro	150 watt	5,1 euro per watt	Italian article
Aqamai LRM	465 euro	87,5 watt	5,2 euro per watt	Test
Zetlight UFO ZE-8000	500 euro	91,5 watt	5,5 euro per watt	Test
CEAB Slide & Led	2.700 euro	275 watt	9,8 euro per watt	Review
Sicce GNC 466	1.592 euro	120 watt	13,3 euro per watt	Receview

Danirref conclusion about our Atlantik V4 Gen2 (please read fixture where you see ceiling light)

“The ceiling light is very well built, the covering is optimal and the application very simple and reactive. The cost per watt is in the average, while the PAR expressed are incredible.”

A Quick Look at Orphek’s ‘Blue Sky’ LED Strip Light

By Dana Riddle

Light-emitting diode (LED) strip lighting has become popular when used singularly or in plurality. In smaller or shallow aquaria, a single strip is possibly enough or can act as supplement to other lighting. In larger aquaria, multiple strips can provide adequate light.

Orphek’s strip lights are a no-nonsense approach to aquarium lighting. An aluminum housing acts as the heat sink and keeps operating temperatures under control, thus avoiding cooling fans. A simple on/off switch controls power to the unit and of course allows optional use of a third-party timer. In short, the unit is robust and reliable.

The unit marketed as ‘Blue Sky’ is a mix of two LEDs with distinctly different spectral qualities. The blue LEDs (12 of them) peaks one at about 450nm and the others (six) at about 495nm. These wavelengths are important in zooxanthellae photosynthesis – chlorophylls a and c₂ utilize blue while the accessory pigment peridinin absorbs green light up to about 450nm. See Figures 1 – 3. These wavelengths are also away from protective xanthophyll absorption – a plus photosynthetically speaking. Figure 4 demonstrates Photosynthetically Usable Radiation (PUR) of the ‘Blue Sky’ luminaire and sunlight.

Figure 1. Spectral quality of the ‘Blue Sky’ LED light.

Figure 2. ‘Blue Sky’ LED spectrum by 10nm bandwidths.

Figure 3. Cyan and green wavelengths are important in coral photosynthesis.

Figure 4. The Photosynthetically Usable Radiation output of the ‘Blue Sky’ fixture is about 15% greater than sunlight.

Judging lighting on a strictly visual basis is subjective, but I found the light to be pleasing. It avoids the ‘Windex’ look of LEDs with shorter wavelengths yet can still provide radiation to cause fluorescence (‘pop’) in proteins found in many corals.

Intensity is surprisingly high for a fixture drawing only 33 watts. Photosynthetic Photon Flux Density (PPFD) was 190 µmol·m²·second at 19 inches (48 centimeters) from the light (‘air’ measurements.)

Testing Protocol                                                                                                                                                

Spectral quality was measured with an Ocean Optics USB2000 fiber optic spectrometer. Data were exported to an Excel proprietary worksheet for further analysis. Photosynthetically Active Radiation (PAR) and reported as Photosynthetic Photon Flux Density (PPFD) were measured by an Apogee Instrument’s MQ-510 quantum meter with the ‘improved’ sensor. Photosynthetically Usable Radiation (PUR) and Correlated Color Temperature (CCT, reported as degrees Kelvin) was estimated by a Seneye ‘Reef’ device.

Lighting the Aquarium: Orphek’s Atlantik V4 LED Luminaire – Photosynthetically Active and Usable Radiation

By Dana Riddle

Lighting an aquarium would be a simple affair if only aesthetic considerations mattered, however advanced aquarists’ goals often include husbandry of plants, algae, corals and other photosynthetic organisms.

To that end, it was originally suggested that only ‘intense’ lighting was required, and spectral characteristics were of a secondary concern. Our understanding of the needs of reef organisms has advanced over the years.

In this installment, we’ll look at two important lighting parameters –

Photosynthetic Photon Flux Density (PPFD) – often referred to as simply

Photosynthetically Active Radiation (PAR with a bandwidth of 400-700nm)

and Photosynthetically Usable Radiation (PUR.)

These two categories can not be mutually exclusive. A lighting source of high intensity (PPFD) and low useful output (PUR) has few practical applications, while the opposite is also true – low PAR output with high PUR is of limited usefulness.

This time, we’ll look at PPFD and PUR generated by ultraviolet, violet, and blue LEDs in an Orphek Atlantik V4 LED luminaire.

The procedure used was as follows.

Black poster board with a hole exactly the diameter of the lens of each LED allowed measurement of individual LEDs (although the thick plastic cover of the luminaire allows some blending of light from adjacent diodes.)

A Li-Cor LI-1200 quantum meter’s sensor (calibrated for ‘air’ measurements) was placed directly over the LED and the result (as µmol·m²·second) was recorded.

PUR was estimated through use of a Seneye Reef device that reports the result as a per centage.

The Seneye estimates PUR by comparing red, green, and blue outputs. Photosynthetic efficacy was estimated by multiplying PPFD by per cent PUR.

While the procedure is not perfect (particularly with LEDs producing radiation outside of the PAR sensors window of 400-700nm) it does allow a rough estimate of performance.

Ultraviolet Radiation                                                                                                                                               

This luminaire contains 4 LEDs producing UV radiation with peaks at 382, 383, and two at 384 nm.

These wavelengths are useful in photosynthesis – they can be absorbed by chlorophylls a and c2.

They can also excite fluorescent proteins found in many corals. There is also the possibility that these can induce the expression of some of these colorful proteins (both fluorescent and reflective in nature.)

Violet Light                                                                                                                                                                 

Ten violet LEDs are found in this luminaire, with peak outputs at 410 to 428nm.

Some of the comments made about UV radiation are applicable to violet wavelengths as well.

Blue Light                                                                                                                                                                  

Water appearing blue to our eye is the hallmark of clear oceanic waters, hence blue light makes a reef aquarium appear natural but more importantly, chlorophylls absorb this light and use it in photosynthesis. This luminaire contains 32 LEDs producing blue light, ranging in peak outputs from 431 to 473nm.

Using the techniques previously described, these are the average PPFDs of these LEDs.

Figure 1. The Li-Cor PAR meter will under-report PPFD of ultraviolet and violet LEDs since the sensor’s cutoff is at 400nm. The blue LEDs are powerful. PPFD is reported as micromole per square meter per second (µmol·m²·sec.)

As mentioned, PPFD is only part of the story. We’ll now multiply the PPFD values by PUR factors obtained through use of the Seneye device. These are the results.

Figure 2. Using factors generated by the Seneye device, Violet wavelengths are most efficient (87%) in the promotion of photosynthesis, followed by Blue at 80%, and finally UV at 74%.PUR is reported as micromole per square meter per second (µmol·m²·sec.)

Next time, we’ll look at other bandwidths and discuss their importance.

SPS reef tank lighting made simple and stable.

You may have already caught the latest BRS TV episode that focuses on lighting; episode 11. The series has been developed to cover all key aspects of a new reef tank set up based on a number of options at various budgets. In this episode they explore lighting and a variety of ways of achieving success.

15:01 The video discusses the option of panel style LED lights that provide an alternate to T5’s for full coverage. Orphek Atlantik series do exactly that. 

15:08 shows that one Atlantik v4 Gen 2 light will provide enough light coverage for LPS and Soft corals

15:11 Whilst for show stopping SPS tanks, 2 Atlantiks provide a highly diffused light source that wraps around the corals and is almost impossible to shadow.

15:19 The performance of the Atlantik v4 means you can suspend the lights up to 24’’ above the tank to provide even coverage.

36:30 The Atlantik v4 offers the most comprehensive solution for a 4ft tank with 2 lights costing less than $2000. Arguably the best value v performance option on the market.

The Par achieved on a custom setting and not full power. The Par spread is incredibly even across the whole tank.

Orphek Atlantik provides the real alternative to T5’s for full coverage and a highly diffused light source. The series delivers the perfect spectrum and par to create show stopping SPS displays and gives value for money due to the lower number of lights required to achieve great results.
