Freshwater, saltwater and reef aquarium LED lighting.

Marineland’s latest innovation brings the light to the inside of your aquarium. Exclusive in-frame mounting allows you to see the light without seeing the fixture, and integrated cord routing helps to complete the illusion. The directional adjustment dial gives you the ability to shine the light where you want it. These lights are fully submersible, and come with suction cups to give you endless possibilities on how to use these systems.

  • Pleasant general illumination for most aquariums
  • Control over the light while keeping the consumer’s hand dry.  Also allows for a night light feature.
  • Energy and cost savings
  • Unlimited opportunities for customized lighting options
  • Provides powerful light without adding distracting fixtures on top of the aquarium
  • Completes the illusion of the hidden fixture
  • Allows the consumer to direct the light where they need it

  • Reduced cord clutter
  • Adjustable to fit your aquarium
  • Quality assurance

Rated 5 out of 5 by from So Far, So Great!! Ok ..finally went ahead and purchased the 21" Hidden Led - was concerned on how to mount on my Eclipse 3 Hood - was actually pretty simple. Removed the entire light fixture, leaving just the hood, attached the Hidden Led to the back rim and ran the wire through the cutouts in the back ....attach the suction cup-switch to the side and voila! LED is brighter than the fluorescent ..and the "shimmer"action gives the tank a realistic feel. The blue 'nighttime' setting is a lil dark for my taste but can live with it. All and all, pretty happy with the purchase! Will keep ya posted ..but good job so far Marineland!

Rated 5 out of 5 by from Great lighting option This light came with my 27 gallon cube tank. It was easy to clip on and everything on it hides well. I adjusted the angle and it makes the colors on the fish really stand out. The night lighting on it makes the brighter colored fish stand out. I have recommended this lighting system to family and friends for their tanks.

Rated 5 out of 5 by from I love the fact that this has a day and night light. I was very pleased to see how easy this was to adapt to our existing unit and how quickly it was to install

Rated 4 out of 5 by from Much better than the LED hoods These light bars nicely light up the aquarium and don't (yet) seem to have the problems encountered with the LED hoods. Used with a glass canopy, they lend a very nice look to the aquarium.

Rated 5 out of 5 by from Very unique product I bought this light because of the low profile, natural lighting effects, ease of use, and my positive experiences with other Marineland products (filters, tanks, underwater lighting & bubble wands, heaters, etc.) I have bought good products from a few other companies, but I tend to gravitate toward Marineland products, as I know, from past experience, that I am getting top of the line products that last, perform well, have great features, and look great. I know that once I bring home a Marineland product, I'm not going to be disappointed. I know that the product is going to enhance the tank without taking the focus off the fish, not to mention ease of use. It's not bulky or heavy, and allows unobstructed view from the top of the tank for those who have glass tops. Plus, it makes it a lot easier to perform water changes and other maintenance to the tank, because you don't have to move a bulky light hood every time you need to gain access. I like that there are different options for mounting it- a deep groove to slide the inside lip (of the upper black tank rim) into and suction cups that allow it to be mounted to the tank glass. The light angle can be changed by turning the built-in knob at one end of the bar. The only thing that I would like to see in the future is an option to replace the light tube part. Other than that, this light is THE answer to eliminating extra bulk and creating a streamlined, elegant aquarium

Rated 4 out of 5 by from Had problems; Marineland replaced the unit immediately. I wrote a review which wasn't flattering and was contacted by Marineland to review the problems I experienced. Because the original unit wouldn't adjust the lighting down I was sent a replacement. The new unit adjusted as desired and is now a supplement to the main lighting, which is the 48-60 Reef Capable with timer. The extra lighting is a real plus in my 75 gallon reef system although it is designed for smaller aquariums. The concern shown by Marineland for satisfying their customers was in my opinion, superb.

Hi!! I've bought my 56 gallon column tank aquarium last year, and the top part is broke yesterday can anybody tell me where I could find a replacement for my glass hood, I'm looking for the plastic hood with light, 

Asked by: Renato
We do not make a black plastic full hood for specialty tanks like this one, only for standard sizes. You would need to get a new glass canopy. You can either order it through a local fish store or you can get it through www.thatpetplace.com or www.petswarehouse.com.BREX

I have a aquarium in a yacht the depth of the tank is 12" the reason I like think this light would be good is because the top of the tank is a non transparent water tight door .is this light capable of growing coral . Is it enough of the right light .

Asked by: Capt kev
The Hidden Accent LED Strip Light with all blue lights is rated for corals. It is 460 nm and 17" long. However, you would still need a 10,000 - 14,000 Kelvin white light as well. I would recommend the Reef LED Strip Light for this purpose. It also has blue light, but it combines both types of lights. It is low profile, and comes in lengths from 18" to 48".BREX

I have a 55 gal. tank that I bought as a kit that came with 2 of your lights in 2 hoods can I add these in addition and will it support plant life? Submersible?

Asked by: Patrick5826
Yes, you can definitely add these to supplement the original lighting. They do support low to moderate light plant life. Yes, they are fully submersible. They are intended to be mounted in the frame, and rotate to allow directional adjustment.BREX
