This is the new Italian ceiling light Aqamai LRM, and I have to say, it really impressed us, especially the instrumental data. 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)

Construction

  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 PAR LUX PUR Consumption
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. 

Consumption

  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. 

Maintenance Costs

  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. [Translated by Agnese Poggi]
