The new LED bars Orphek OR3 Blue Sky in the DaniReef LAB – review

After Orphek made the announce we were all extremely curious about these new Orphek OR3 Blue Sky, also because we did test the previous OR2 Blue Plus and we were looking forward to the comparison (here).

These bar, as well as the previous OR2, are beautiful, solid and they seem very well made. The shell between the ceiling lights is exactly the same as before. Orphek says that soon it should be available the dimmer that controls the light in the switching on and off. We’re anxiously waiting for this dimmer because it’s the only thing that’s missing. Even though dimming is less important in LED bar than in other types of ceiling lights. But we’ll see this aspect later.

The peculiarities of the Orphek OR3 Blue Sky

This new LED bars of the lucky series OR3 has only two types of LED, 450 or 470 nanometers. This ceiling light is admittedly blue. We already said, some weeks ago, that this news was unexpected, because we really liked the Blue Plus version that’s still sold and still at the forefront, as you can also read in our DaniReef LAB (here). But Orphek, through its study on corals and reefs, as well as on our aquariums, came to the conclusion that this new version is an evolutionary step towards the future, in particular for the appearance of the corals and their fluorescences. In its page Orphek retraces the history of the Blue Sky version, appreared for the first time in 2018. Back then the spectre could also tend to green, that at first seemed useful somehow, but then the aquarists voted it down. That’s why the new Blue Sky is built on two wavelengths only, 450 and 470 nanometers.

As Orphek itself says: “Corals and anemone have at least two types of combinations of color: the fluorescents and the non-fluorescents. There’s some fluorescence where compound absorbs lights and emits it (fluorescent) at a greater wavelength, so these kind of compounds shine (or “burst”) under UV light, purple or blue, while the non-fluorescents don’t shine at all, they seem opaque under the same light. This different behavior is due to what’s called chromoproteins. They’re produced by corals and anemone“. And the Blue Sky has been studied in order to make these fluorescences stand out.

The suspension kit

The bars are sold with a suspension kit, pretty short, so if you’re planning to hang them to the ceiling you have to buy an extention. This kit suits the Orphek suspension arms or the kit to hang them with the Atlantik V4. We’ve already said this, but again, the Orphek OR3 Blue Sky are very well build. The external refinement works as passive heatsink and, given the weight in aluminium, we’re sure that these LED bars won’t have any problem of overheating. And the assembly is basically perfect.

The Programming

The LED bars, generally, can’t be programmed, and the Orphek OR3 aren’t the exception, at least at this day. Some bars of the competitors provide an equipment with a controller for the dimming, or at least it can be bought singularly. Orphek has announced the release of a similar dimming, but it’s still not available. And with LED bars in general, I think the problem is relative. The spectre has to be decided based on the bars that you want to couple and you can make a sort of dimming by switching on a bar at time. Let’s be clear, I’m not saying that dimming isn’t important, but when you use ceiling lights the lack is far more noticeable.

Differently from usual we can’t give you consumption and values of each LED singularly, because these bars switch on all the LED simultaneously.

The values we measured and our working method, called DaniReef LAB, are on page two.
