Azurelite Led Flashlight Review by recifalnews.fr (nov 29 2014)
The uboxing of the Azurelite flashlight from Orphek have been made by Alderas and is available here (in English) or here (in French)
In the first place, let's remind that this flash lite can be usefull in the folowing situations:
- Observes the corals after after light's out
- Stalk, after light's extincton, the shy or undesirable animals and discover what's happening in the caves and other dark places of the tanks
- When you are shopping for corals, discover their fluorescence if the tank lighting is not good enough.
In order to estimate the usefulness of a such product, this test aim at determine if the Azurelite is assess coral fluorescence quickly and easily. To achieve that, 10 coral have been photographied under different 5 lightings :
- Led pendant Evergrow, blue and white led
- Led pendant Evergrow, blue and white led + Azurelite
- Led pendant Evergrow, blue led
- Led pendant Evergrow, blue led + Azurelite
For each coral, the photos under the five lights are presented in this order.
For information, my tank, that have been used for this test, is young and its corals are quite small.
Photos have been took by night, without light in the room, by a Canon 550D with a camera lens 75 - 300mm with 3 extension tubes (total length 5 cm), on a tripod and a self timer. photos with light traitment 3,4 and 5 have been made with a personalized white balance,by a photo of the white plastic Plenum , made very closely and under blue ligthing, without Azurelite
Contrast and colors have been automatically adjusted with Gimp 2.6, in order to obtain a rendering closer to reality.
Moreover, I begin in macro protography.
Test 1: the Silunaria sp. green with high fluorescence
To say the least, the Azurelite is able to strenghten fluorescence when the coral is under normal condition and secondly it is also able to relieve it , even if it is the only light source. This statement confirms the usefulness of the Azurelite, at least for the coral with strong green fluorescence.
Test 2: red Zoanthus sp.
This zoanthus are red, green and blue, but in normal conditions, only the red and the green are fluorescent. This step shows that the azurelite is able to relieve the red fluorescence. However, no surprise with the blue part of the Zoanthus, which is not fluorescent with the normal lighting of the tank.
Test 3: The blue Palythoa sp.
Under normal lighting, the turquoise blue fluorescence of this coral is not so obvious to the naked eye and difficult to catch with camera, but is still observable. Unhappily the turquoise light is not able to relieve this little fluorescence, indeed the palythoa and its plug are highlighted in the same colour. On the contrary, the green/yellow fluorescence of the heart, which is weaker than the blue one, is really viewable, which is a very good point foir the Azurelite
Test 4: The blue Caulastrea sp.
This time, the blue fluorescence is stronger and is strenghten by the Azurelite. Hlike with the palythoas , the yellow fluorescence of the heart is more observable with the Azurelite than with the pendant.
Test 5: The green Echinopora sp. with the green polyps
The purple of this coral is not flurorescent in normal conditions and Azurelite can not do better, the blue color on the second photo is not fluorescence. One more time, the fluorescence of the green/yellow heart is more visible with the Azurelite than in normal conditions. Test the azurelite on my tank make me realize that my actual lighting don't show all the beauty of my corals.
Test 6: the purple and green Sanctithomae sp.
One more time, the purple is not fluorescent, contrary to the basis. One more time, the Azurelite enhances fluorescence which are hardly visible in normal conditions. Nonetheless, you may have noticed that the Azurelite gives a truquoise blue color at everything which is not fluorescent. I was afraid that this lighting do not permit to appreciate the delicacy of the little outgrowth of this very atypical coral, but I was wrong.
Test 7: the red Entacmea quadricolor with green reflects
Without any surprise, the Azurelite is able to show the red fluorescence. On the contrary, the green reflect we can oberve with the blue lighting only is not relived by the Azurelite .
Test 8 : The green Rhodacthis sp. with the deep purprle basis
I love this coral for this contrast between the high fluorescence of its the outgrowth and the deep color of the basis With the Azurelite, this contrast is quite well conserve. As we already observed, the green fluorescence looks more yellow with the flashlight, even if the dominant color remain green.
Test 9 The green and greenEuphyllia sp. !
Azurelite succeed to shox the green fluorescence, but it colors themonth in blue on the second photo, which is a surpriseful artifact. However this problem does not occur anymore if the Azurelite is used alone .
Test 10: The green Acroporas sp. which suffered in the past
I have obtained this acropora which had lost a part of its tissue at its basis, probably due to a lack of light . With a classic lighting, it is possible to not detect this kind of mater, due to the coral position and the incidence of the light, wich never changes. With the Azurelite it is now possible to check the good healthof the tissus the less accessible, and in a very easy way, thanks to the fluorescence.
This test has proven that the Azurelite, as small as handling, is fully cabaple to relieve the coral fluorescence. Moreover, this amazing tool axraed me that my actual lighting is not able to fully relieve the entire fluorescenece of my corals. I also understood that the Azurelite will help to check the if the basis or the heart of my biggests colonies is not whitening.
