The ceiling light is very thin, and is black with white sides and a double power cluster. It’s a popular look for ceiling fans today and it’s an especially American aesthetic.
Technical characteristics of the Aqamai LRM
It has 8 LEDs with different colorations, divided into 6 channels. So we have 15 LEDs per cluster. The “cool white” LEDs are very interesting, they’re 6 Nichia NVSW219C , with a CRI > 70 and 180 lumen/watt, a very high value.
In addition, there are two UV LEDs by SemiLEDs of 405 nm, 4 Indigo SemiLEDs of 415 nm, 6 Royal Blue Nichia NCSC219BT (very beautiful), 6 Blue Nichia NCSB219BT, 2 Green Nichia NCSG219BT, 2 Red-A Nichia NCSR219BT, and finally 2 Red-B OSRAM Oslon SSL.
- Power: 100 w
- Dimensions: 36 x 16 x 2(h) cm
- Price: 465 euro, vat included ($560 US)
The Aqamai LRM is well constructed, just 2 cm thick, with two cooling vents and two clusters of lights. The design is very similar to that of brands such as the American radion and AquaIllumination.
The ceiling light can be ordered with a wireless app, available for Apple or Android. You won’t need anything else, just connect the plug and it will create its own WiFi network. It’s a very straightforward solution, but it penalizes anyone that who doesn’t have either of these two systems. The app works very well, and it’s very easy to use.
Above, you can see the the manual command as it appears on iPad, where the two lateral sliders represent the power, and the two circular selectors the color gradation.
Aqamai LRM – our survey
As usual we used our Seneye Reef probe for the survey, whose software permits the detection of lux, PAR and PUR.
We did 5 measurements, all of them in the center of the ceiling light’s cluster. In uniformity with previous measurements, we were 20 cm away from the ceiling light, and in this position we measured the maximum total power expressed, and then the maximum power of the 6 channels individually.
So in this way we could measure each cluster’s maximum power, and then the power of each channel. We also measured the absorbed power.
As you can see from the chart these are the observed measurements:
- PAR: 1.088
- Lux: 40.165
- PUR: 74%
And here below you can see the 6 channels individually. We left only one channel 100% turned on and alternated all the channels in turn.
|Channel Cyan||318||11,760||76%||23.24 w|
|Channel Blue||294||10,874||86%||24.41 w|
|Channel Purple||62||2,292||87%||13.00 w|
|Channel Red||108||4,007||90%||7.62 w|
|Channel Green||50||1,852||32%||6.72 w|
|Channel White||265||9,800||58%||2.15 w|
|All the Channels||1,088||40,165||74%||87.5 w|
It’s easy to notice from the chart that the majority of PAR and LUX is from channels Cyan, Blue, and White, in that order. The other three channels don’t affect much.
I’m sure you didn’t notice this thing: if you consider the channels individually, they express much more power than together. Maybe the chosen chip or the power supply can’t bring the LEDs to their maximum, or it’s possible to take power from one channel to give it to another, like AquaIllumination HD.
The test of the instant consumption was possible thanks to the very useful tool RCE PM600. The result is already given in watts.
The calculation of the maximum absorbed current, that is the power, is 87.50 watts.
It’s a lower value than the declared one of 100 w (-12.5%), which can be due to a different rotation system of the vents.
The comparison between other ceiling lights on the market
We’re referring to the measurements we’ve done before about other comparable ceiling lights. In particular, we can refer to the last Philips CoralCare (article), the GNC 466 (review) and the Maxspect Ethereal (article). The Philips registered 1,496 PAR and 55,230 Lux, the GNC 696 PAR and 25,697 Lux while the Ethereal 689 PAR and 25,440 Lux. But the most specific comparison can be done with another cluster ceiling light, like the Zetlight UFO (article). It has just one cluster and it registered 791 PAR and 29,193 Lux (consider that Aqamai has two clusters and not one).
According to these values we have optimum results for Lux and Watt, but we have to remember that we have a single cluster ceiling light so the comparison needs to be done with equivalent ones, like UFO and radion.
|Ceiling light||PAR||LUX||Watt||Price||Lux/watt||euro per watt|
|GNC 466||696||25,697||120||1,400 euro||214||11.7|
|Philips CoralCare||1,496||55,230||190||749 euro||291||3.9|
|Maxspect Ethereal||689||25,440||130||500 euro||196||3.8|
| Zetlight UFO ZE-8000||791||29,193||91.5||500 euro||319||5.5|
| Aqamai LRM||1,088||40,165||87.5||465 euro||459||5.2|
So, it has superior lux per watt than the Philips CoralCare, but its optimal result will be related to a shorter surface. We think the optimal coverage is about a 50×40 cm area for hard corals (SPS).
The comparison with a Radion G2 PRO, our review, not on the market anymore, but it’s the most recent Radion we could try, has in the middle of the ceiling light a value of 2,117 PAR, 78,049 Lux and PUR about 72%. In this case the return is almost half.
The Aqamai LRM costs 465 euro.
Its absorbed power is 87.5 watt, so it has a cost/watt of about 5.2 euro for each watt. If you take a look at the chart below you can see some comparisons with other ceiling lights we’ve tested.
|Ceiling light||Price||Consumption||Relationship between euro/watt|
|Maxspect Ethereal||500 euro||126 watt||4.0 euro per watt|
|Philips Coralcare||749 euro||190 watt||3.9 euro per watt|
|radion XR30w G2 PRO||790 euro||170 watt||4.7 euro per watt|
|radion XR30w G4 PRO||915 euro||190 watt||4.8 euro per watt|
|OceanLed Sunrise 600||870 euro||180 watt||4.8 euro per watt|
|radion XR30w G2||690 euro||140 watt||4.9 euro per watt|
|radion XR30w G4||760 euro||150 watt||5.1 euro per watt|
|Aqamai LRM||465 euro||87.5 watt||5.2 euro per watt|
|Zetlight UFO ZE-8000||500 euro||91.5 watt||5.5 euro per watt|
|CEAB Slide & Led||2,700 euro||275 watt||9.8 euro per watt|
|sicce GNC 466||1,592 euro||120 watt||13.3 euro per watt|
The ceiling light is built very well, very thin, and we really like its software. The cost per watt isn’t the best in the category, but it has a high number of LUX thanks to the concentrated cluster, much more than what the power pre announces. Moreover it’s convenient that it has its own Wi-Fi network and that it doesn’t require an extra tool to be configured. And we will talk again about the configuration in another, specific article.
Questions and comments are always welcomed.
