How to value these numbers in aquarium?
This is a good question. At first we thought that we could transport these values to the aquarium tout-court. Than we filled the aquarium, insert the probe and redone the measurements. We fazed but, as we have already said in elsewhere, we’re going to talk about this in another article. Basically, while at 20 cm the result is practically the same, as we progressed, thanks to the glass and the water itself reflecting the light, we found even the double of the values measured in air. Obviously this isn’t a detail that can be standardized, so we think that our method of calculation is the most correct, and the best for the comparison of coverages of different ceiling lights.
The comparison with other ceiling lights on the market
Recently we started to use the new Apogee’s Quantum Meter MQ-510. For this we can’t completely compare the data of other ceiling lights because before we used the probe Seneye.

The energy per watt is less than the similar Philips Coralcare, but the maximum value is higher. We can say they have similar energy even considering 20 watt less for the consumption of the Philips. This probably depends on the specific LED. The economic efficiency is slightly less then the Philips. In any case, valus of respect. And for now it has the record of energy produced.
Maintenance costs
The ceiling lights ATI Straton cost 890 euro.
The absorbed power is 211 watt, then the relationship cost/watt is 4,22 euro for each watt. You can consult the following chart for the comparison with other ceiling lights. Notice that they’re order for decreasing efficiency, so the best ones are on top.

The ceiling light is extremely well build, firm and solid. Very beautiful. The energy efficiency is high but the cost per watt is rather low. The values are perfect for nanoreef and for aquariums until 70 cm per side, both for breed SPS and every other animal. Increasing the sizes of the aquarium the covering decreases, so I suggest 2 of these ceiling lights in 120 cm and 3 in 180. The energy is linear on the water column.
