CURRENTUSA 48 - 60" Inch Orbit Marine LED Saltwater Reef Marine Aquarium Light | 24 Hour IR Lighting & eFlux Wave Pump Control | Adjustable Color Spectrum for Fish Tank (4103)

This is the third assembly I have bought. The other two were the 24" and 36" lengths. They are still performing beautifully. The top concern for people looking to buy will most likely be "Will this be enough light for coral growth?" That is the reason I have continued to buy additional units. The pictures show just one example of happy frogspawn corals. The lights are 2" above the water surface and the corals are about 24" deep. These corals were reluctant to open up when I first got them, and they were also in a similar state when they were in the display tank they were purchased from. After a few weeks of acclimating, they are vibrant in color and full in shape. These lights have separate white and actinic (blue) LEDs that can be controlled to be on or off separately. I really enjoy corals that fluoresce. This fixture has several ways to enjoy seeing your corals on display. One method is to time your viewing when the white lights are fading at night and the blues are left on.The remote control can also be used to override separate color intensities by single percentage increments, and easily resume normal programming when done. The remote can also do something that is novel that can't be done with traditional light fixtures. There are four settings at the bottom of the remote for dynamic effects. These are partial cloud cover, partial sunlight, moonlight and thunderstorm. These settings continuously change the light intensity which allows the viewer to observe the inhabitants under shifting light conditions. It's very cool to see the corals under a variety of lighting changes. The unit has two pre-programmed timers for light duration and the ability to create two more programs of your own design. They also feature a ramping on and off of lights so that the change is gradual rather than instant. Maybe that never harmed any fish or coral, but it's a nice benefit for those who are interested in creating as natural of an environment as possible.The remote comes with a spare battery for whenever the time come to replace the original. Whereas I have three of these units, I am still just using the remote from the first box I opened for all three fixtures. There is some assembly required, but it is only connecting of the cords. When your package arrives don't panic if you don't find all the parts immediately. You may need to look in the other end of the box to find another box with more parts inside. The cord lengths are generous. There is about 6 feet from the wall socket to the the adapter, and another 6 feet to the controller. There is about a 4 foot length from the controller pad to the light fixture. For each model's length range, the smaller value is the length of the light fixture and the longer value is obtained by extending the mounting rails to their maximum. For small lights with low power draw, they sure are intense. I've tried to turn the fixture over to clean when it is still on and the light is to intense to be able to do that comfortably.

This is a good light for seeing the fish and owner enjoyment. If you are a hard core reef keeper with fancy coral you will need to get more than one to get the PAR you need. If you have a nice fish only tank and just want to see the fish this is great. I actually put it on an African cichlid tank and it works great, brings the blues out in my fish great and I like that it will run a full day and night cycle with a dawn and dusk without my intervention is great. This is not the brightest light by far, but it is also very reasonably priced for what you get. Like I said if you are a hard core reef keeper this is probably not going to make you happy unless you have a very, very shallow tank. If you don't need a bright light and want a nice light to see the fish this is a great light, best one out there in my opinion. There are many brighter ones, but they cost a lot more too. This light uses a lot of low watt LED's. It is cheaper to put a lot of low watt LEDs then fewer high watt LEDs. The problem is that the low watt LEDs don't penetrate the water as well as the high watt ones do. High watt LEDs are good for growing things, low watt lights look nice and are cheaper to build and you have more ability to use different color LEDs if you have a lot of them. The dynamic lighting modes are what sets this light apart. If you have not yet, go on YouTube and watch the videos. The modes are pretty cool. The lightening mode is the favorite of my kids and it is pretty realistic for a light with a small controller. Other LED lights out there are much brighter, but you pay more, they are harder to program and they turn the white lights on or off and the blue lights on or off. This fixture is able to vary the lights much more. It has a nice dawn and dusk feature that is fully programmable and being able to sit and watch the simulated clouds go over my fish tank is pretty fun to watch. Honest truth is that as far as the fish are concerned they don't really need any light. As long as they can find the food that is all they care about. This light is for the owner and if you don't have to grow plants or coral, why waste the money, energy and time on a higher watt light that you have to clean the algae in the tank more? Just wish they made the freshwater plus light with the controller...
