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.

Consumption

The measurement of the consumption was made possible thanks to the useful device RCE PM600 that can also measure the Cos(fi) (or power factor). The result is already given in watt.

Here above there’s the maximum power and below the Cos(fi).

The calculus of the absorbed current, that is the power, is the following one:

Ceiling lights Reef Flare S: 65,04 watt. Considering that 17 cm the ceiling light has at the middle 623 μmol m-2 s-1, we can guess that it will have a peak value of 9,58 μmol m-2 s-1 w-1 (PAR per watt).

The value is slightly lower than the declared 70 watt, and allegedly this depends on the system of vents, but it’s higher than what declared on the box, that’s 54 watt.

The comparison with other ceiling lights on the market

Recently we started to use the new Apogee’s Quantum Meter MQ-510.

The energy per watt decreases linearly in the different distances, as we expected by a diffused ceiling light, but it’s penalized in its peak value.

Maintenance costs

The ceiling lights Reef Flare S cost 300 euro.

The absorbed power is 65 watt, so the relationship cost/watt is 4,6 euro per watt. For a comparison with the other ceiling lights you can consult the following chart:

The ceiling light is very well build, the refinements are really interesting. It’s a heavy ceiling light and it’s very solid. Moreover, seen its heat sinks and the big vent we expect it won’t have any problem with heat. It’s very easy to set and the app is very well done. Easy but complete. Useful that you can always see the temperature. I’d suggest you to set the ceiling light at its maximum, anyway, so that you’ll have its best, with a fast or slow switch on and off, depending on your needs. It’s very easy to use, expecially if you choose their preset programs. The PAR are very distributed, which is strange for a single cluster lamp, with the only problem that if you increase the coverage then the peak values tend to decrease. What that really stands out is the ability to create a very well diffused light, perfect for LPS and soft corals in a nanoreef until 60 cm, more than what the competitors can promise. But with only one of them it would be difficult even to grow simple SPS. The cost per watt is good and the peak PAR per watt are very low. Allegedly it’s similar to the Hydra Prime, even if we didn’t measure it yet. The energy produced is in the average but it can’t compete with other ceiling lights that consume and cost the double or more.

Question and comments, as always, are very welcomed.
