Hidden LED Strip Lights is rated 3.8 out of 5 by 30.
Rated 4 out of 5 by from Good customer service, nice low profile light I purchased one of these LED strips that stopped working after a few months. Customer service was excellent; over email they agreed to ship me a new light at no charge. They only asked for a lot number on the unit and where to send the replacement. The replacement has been working great for over a year now and gives a nice low profile on the tank. Bright enough for the anubias in my 20 long.

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 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

Does the light emit UVA light? i am interested in it for my turtle tank set up

Asked by: Dave204
Hi Dave204. This does not emit UVA light. You will need to get a turtle specific light.

I recently bought a 38 gallon bow front tank with 2 small strings of LEDs clipped to the front edge. The night light part worked at first, but they have since gone to flickering so badly that I just turn them off. Can I get a replacement? Thanks

My hidden led light won't turn on tonight. I have tried turning it off and back on. Unplugging it. Switched it from whites to blue and nothing.

Asked by: tonyaleekent
Make sure the power cord is connected properly to the end of the light itself. If so, the transformer is probably faulty, and we would recommend you call us if you are within your one year warranty. Our number is 1-800-322-1266. BREX

Can these LED lights work on fresh water plants? I want to get the 10 gallon LED kit (colorwheel) and am not sure if the plants I put in for the fish will die... I definitely want live plants and this will be an entry tank until I can buy a bigger tank

Asked by: Ironrey
Well, for a 10 gal it will be fine. K values aren't a good guide for plant growth. You just want to be sure it's in the 6500K area as starting point. The PAR values are critical (essentially gives you penetration capability through water) and these are pretty low for depths more than about 8-10" if you want lush plant growth.
