Replicate Natural Light

The Marineland Double Bright LED Lighting System provides a vibrant and natural looking light that glistens and creates shadows throughout the water adding depth and dimension to your tank's interior.

The entire lighting unit is powered by a single low voltage AC cord to use less energy, save money, and help protect the environment.

Read this and compare to the REEF lights, if you're interested in putting one of these lights on your tank.

I received my 24-36 in. Marineland Double Bright LED Light - 8 x 1W white - 4 x .06W blue and was delighted when the light finally arrived.

The fixture packaging was simple, yet sturdy and protective of the light fixture. It comes with two parts: the main body and the power cord. Easy, no brainer, installation!

Just so you know, this light is going on top of a heavily planted, freshwater, 30 gallon tank, with the dimensions of, 30x18.5x12in. WxHxD

Look wise, what was truly attractive, was the body being slim and sleek. No more clunky hood to stare at anymore!

After reading the directions, a disappointing tidbit, was that Marineland (manufacturer label) required and recommended that the light be placed on a tank with clear acrylic or glass covers to protect the LEDs from water damage.
My original intention was to leave the light directly above the tank, using the built in brackets it comes with.

The unit is completely silent. A big difference for those that have fans for high output light that run very hot.

The light output itself was sufficient, while not being the brightest I've seen. It doesn't fill the tank with light like most lights do. It lights up the tank like how the sun lights up water when it shines through it. It's like the light waves on the bottom of a pool when the sun is shining through the moving water surface. Imagine the shimmery effect in water, but with eight fill sources of light gleaming into the tank and bouncing off the tank floor.

I have a 55 gallon aquarium, 48" long rectangular. Nothing special. For a long time I've had a 48" fluorescent twin tube light, but was getting algae. The "Pet Store Guy" said to turn my lights on more, and it should help get rid of the algae. The only problem, my bulbs were as old as the fixture, and not putting out the UV light they need to in order to kill the algae. He did say that if my bulbs were old, it may not help that much. He was right. When I started looking at replacing the bulbs, they were $15-$20 each. That means $80 a year. He mentioned LED lighting, and so I started looking.

When I saw this, I realized it would pay for itself in just over 2 years. Pretty cool! I couldn't 1-click buy this fast enough.

When I put it on my setup, it took a bit to get used to the lighting. The Marineland Double Bright is pretty blue intensive. I was used to the full spectrum thrown by my florescent. This thing is very bright, as bright or brighter than the twin fluorescent. I've had it now for about 3 weeks, the algae growth has slowed to a minimum (My pleco is keeping up with it easily), and I'm very happy.

It's plenty of light for plants, but I have Silver Dollars, and well, you know ...

Another plus is the fact that this light does not affect the temperature in the tank nearly as much. I noticed the temp dropped 2 degrees. It now has the temperature I set on the heater, which is awesome. I like the way this light does not sit directly on the top of the aquarium. It's legs lift it about 2 inches above the rim (I use glass covers) and looks really nice. Also being smaller, it's easier to get to my filters and what not.

I only have 2 complaints:
- Lunar mode is on the same switch as regular.

I bought the Double Bright 18-24, for a 20H planted tank. As a techie I have to say I like the move forward to LEDs. In theory they should be more efficient. In this case these lights are quite a lot brighter than their fluorescent counterparts, although the light dispersal pattern is a lot narrower. This could very easily be remedied by changing the reflectors for future models. I have only seen one unofficial spectrum sheet, but supposedly these lights do cover the proper wavelengths for peak absorption. I have a few plants that require intense light and they certainly haven't suffered from the change, although growth rate remains the same.

The nightlight function was another factor that heavily influenced my decision to buy this product, and I have certainly not been disappointed. The light itself is dark enough to let the tank inhabitants sleep/roam in peace, yet you can still watch them. The shimmer/water ripple effect is certainly interesting but a bit overblown, it seems to shimmer too fast in my opinion. That's about all I can say for now, will write another review in a few months time. Even if this product isn't perfect it is still a good step towards the future in terms of power saving and providing proper care for your aquarium, I would say to buy this product to motivate this company to build more like this, the end result should be more money in the pocket and happy critters/plants.


I've had this light for close to 2 months now and I have to say I happy with the purchase. While my plant growth remains at a constant rate, the quality of the plants has skyrocketed. The plants produce much healthier looking and significantly wider leaves. With a C02 injection system and regular fertilization I wouldn't be embarrassed to call this a high tech system without having to mention high output this or quad that. Overall I would recommend this light.
