经过大约20年的礁石，我可以回顾一下礁石水族馆设备的许多实验，但我将手指放下了一件事：使用蓝色荧光管补充的金属卤化物。看到我的礁石坦克之后，杰克要求我写关于我的经历，并通过使用The The The Plast LED照明在我的坦克上方欢迎一些新东西Orphek Nilus.
Surely I have seen a number of led-fixtures before, but nothing appealed enough to me to consider switching the lights above my own tank. Because I’m interested in what’s going on in our hobby, I did read a lot of information about led.
Based on this, I decided to try to convince the LFS where I usually shop,Aqua Compleetin Rotterdam, to order two Orphek-PR156 fixtures to see if they were as good as I thought they were. In the meanwhile, they also received an AI Sol and to be honest, I was impressed by this light and doubted if Orphek could even match it.
在Orphek PR156 LED到达后，它们挂在AI索旁边的脆弱坦克旁边，至少在眼睛上，Orphek的PR156很棒，他们比AI Sol更吸引我。在LFS进行了一些测试之后，我已经准备好切换到Orphek PR156完全LED。
In the meanwhile, Orphek came up with the Orphek Nilus: the dimmable version of the 156, also including 4 red leds and 4 UV-leds next to the blue and white leds. In total, I mounted 2 Orphek Nilus and one PR-156 above my tank (190 gallon).
固定装置的装箱非常好，设置计时器，并且在几分钟内完成了百分比（每个固定装置都有两个“要设置的LED”）。Orphek Nilus的建造质量似乎做得很好。60个LED安装在一个巨大的散热器上，并与两个粉丝一起安装。这种结构以及镜片（根据Orphek的120度）夹在两层丙烯酸之间。它以时尚的方式设计，除了LED和粉丝之外，设备本身没有电子设备。PCB受到硅环环的侵袭性水分和咸空气的保护。具有专有连接器的电缆通向安装电子设备的盒子，其中可用延伸线。
Setting the light up was an easy job, but the ‘power box’ of the Nilus can be improved: the clock needs to be set again even after a short power loss. The programming is kept in the internal memory though. There is a fan which cools the power box and this fan is very quiet, just as the fans in the fixtures. The fans in the older 156 in the lfs made more noise from the beginning. The Tunze Stream pumps in my tank definitely produce more noise.
Obviously, Orphek has improved things in the Nilus LED as the fans also look different than the ones in earlier generations. The light is not as rich in features as some other fixtures, but so far I have not seen a light which looks as good as what I’m using now. I prefer to have great light all day long over having a light where most of the engineering was probably spent on ‘features’ instead.
So far, I am very pleased. Colour rendering is very good, any cyanobacteria have disappeared, algae growth has decreased a lot both on the glass and on the rocks, temperature has dropped by about 3 degrees Celcius and I decreased the power consumption of my tank by more than 1500 kWh annually. I did manage to get some nice colours under my old lights (2 x 250 W HQI plus 4 x 54 W T5) and the big question was, if I would be able to keep these using the Nilus.
几个月后，我可以得出结论，没有一个珊瑚的颜色降低，大多数实际上有很多改善。同样适用于增长。我的水箱的水深度为28英寸，甚至在水箱的底部，我都有多个蛤and和敏感的SP，颜色不错。也许更重要的是，坦克看起来比旧灯好得多，它看起来清晰又新鲜，而且颜色确实“流行”而不显得不自然，并且一对产卵的糖果bass子喜欢昏暗的功能。
