Italian blog danireef.com made a terrific job by making an extensive review on the Atlantik V4 Gen 2 and we here at AquaNerd are pleased to be able to share this information with our readers. Keep reading below to see the Atlantik V4 Gen 2 product review.
A complete review with PAR Measurements
Forward by Orphek – 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.

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) |

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.”
