The comparison with other ceiling lights on sale
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.
| 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 |
.
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.
Maintenance costs
The Orphek Atlantik V4 cost, without any particular offer, 1099 dollars, that in the actual value, tax included, are 1099 euro. You have to add the price of the getaway of more or less 150 dollars but it can control “n” ceiling lights. This is also often on sale.
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.

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.
