Marineland Double Bright LED Lighting System Aquarium LED Light Fixtures at Linens 'n Things

Excellent quality and reasonably priced. If you like the "shimmer" effect LED's give then this is the right light for it. The light goes only straight down from the fixture unlike T8 or T5 bulbs. Also I think that this light would only fit tanks up to 24" long so all the tanks which it fits are short compared to most other tanks. The short is the problem as the beams of light which this light shines downward are very narrow and don't have time to spread before reaching the bottom of the tank. Some people will be pleased with it as it gives a reasonable amount of light. But comparing the light which it produced to that which the two T8 bulbs that were on the tank before I bought this light had produced...well the LED had more "shadow" arias in the tank and was less visible light overall than the LED. Plus the back wall or just say the sides were not lit by it. They had been/w the T8's. Any plants which the light shown directly down on were doing well but those which you could not see the light beam hitting directly were withering from lack of light. Perhaps in taller tanks such as a 29G this light would work well as the beams would have time to spread out. But I find that in a ten gallon this light has serious drawbacks. Conclusion: If fish viewing is your primary interest then go for it, but if plants are important to you stick/w the T8's for a ten gallon.

Have only had it on the tank for 2 weeks, and I love the amount and quality of the light on my 90 gallon acrylic tank. It is too soon to tell whether it will be great for plants. Some Valisnaria are doing well, and there are new leaves on the Anubias. There are only 2 discus in the tank, and temp is 84 degrees. Definitely recommend this LED fixture.

I bought the 36"-48" version of this light as a replacement for the exact same one (the smaller 24") after my original stopped working. The connection of the power cable and the input on the light housing stopped working, would flicker, or not turn on at all. I assume the issue was likely due to moisture getting in the connection and possibly rusting the metallic contacts, but hello, it sits over a tank full of water, shouldn't it have been built to deal with some level of moisture? Fast forward to receiving the new and improved larger light. The power connection is now hardwired into the light fixture itself protecting it from moisture or water splash. There is also now an in-line detachable connection in the power cable which is not only protected from moisture but also makes moving the light around simple without it having to be attached to the long power cable. All in all I love this light, especially with the new improvements in design from the old Double Bright light fixtures. The LEDs will blind you, but the light in the tank is phenomenal even on deep tanks. HIGHLY recommended.

I just bought the double bright LED system. The slim design is amazing compared to the traditional T8 florescent fixtures. The shimmering effect is very cool and the fish appear to enjoy the lunar lights. The lunar lights are nice since I have nocturnal bumblebee cats and tiger plecos in the tank. In the past I purchased a twin compact florescent fixture with a cooling fan. The fans were loud and sometime did not work. The LED system does not produce heat and no need for loud fans. I recently added some low light plants and look forward to the results in a month or two to see the growth rate. I give this produced an A+. Very glad I made the LED switch.

I must say that this light fixture is 10/10 in every aspect. I love how thin it is which makes it barely noticeable on top of my tank. So much less heat and more energy efficient which is always a plus. The lighting is perfect for my 36", 30 gallon tank. The shimmering effect is gorgeous at night. I simply love it. Also at petmountain prices, you can never go wrong.

This is a great LED light. I just wish Marineland would allow being able to turn off half the white LED's. Very happy with this purchase.

The double bright LED is bright, cool to touch bright white light mimics sunlight, blue moonlight is nice nite light, I got 36" for my 36" tank, glad I did, Worth the money, sleek slim modern design.

I purchased this light for a 50 gallon tank that was 36" wide. Glad I did because the light fixture itself is 36" and the legs stretch to 48". The light is a lot brighter than I expected and lights up the tank nicely.

Have it on a 180 gallon and it looks great. Provides plenty of light without being harsh. Love the night time effect. Not sure about plants liking it yet, too soon to tell. Overall a great light for the price.

I placed this light setup for my reef tank and it looks awesome. The lighting is bright -- it gives my live rock the sunshine that it needs to thrive, and the moon light effect brings out all my little creepy crawlies...awesome, awesome light.

I have a 20 gallon tall tank and this fit perfect. I love the way the light plays off of everything in the tank.

GREAT Light, GREAT Price, GREAT Service. So far I love this light and my plants are still alive and the moonlight is excellent. I have new fish under this light and would definitely buy another.

I've had the 36" light for about 1 month and we like it very much. Use it on a 36"-- 50 gallon tank and it's just right. For anyone looking for a led light, I would highly recommend the double over the single light and to also go with the length that is the same length as your tank. The brightness is excellent, but with either of the lesser options I think we would have regretted the decision. Excellent Price, Shipping Status Updates and Quick Shipping!

These lights are great, really like the Double Bright and the Moon light is really cool. Also a great price on these lights, plus the free shipping. I purchased 2-18" for my 55 gal. tank.

I got the 36"-48" version for my 36" 40g breeder and I couldntve been happier, its suitable for low light plants which is all I really use and the best part is I don't have to replace the bulbs!! Lol

I LOVE this light! I had a light that used 34" T5 lights. They were a pain to find and an even bigger pain in my wallet! I was spending $40 for two bulbs every 2-3 months. That is when I decided that I needed to make a change. I invested in this light and I love it!

The lights are bright, even for my tank that is three feet deep! It's amazing! There really is a natural effect to the lights too. The night mode is nice--we like it when we are watching movies and the fish are still up.

One of the other reviews says that the legs cannot extend, but they CAN. They are a little stiff at first, but with a little work they slide out.

I really like this light and it does provide more than enough for fish viewing and probably low-level light plants. Certainly not enough for high light needs (but that is stated). I agree it would be nice if you could use a timer to switch between moonlight and full light, but can only be done manually. One thing I didn't realize is the legs are not adjustable so the length is only 24" and will not reach across a 30" span.

I probably should have bought the 48" for my 55gal but even with 36"s of light it lights up the whole tank. The night light setting is sweeeeet! its bright enough to see your fish yet dim enough for the dark seeking fish to come out and play. Plus the shimmering effect really does imitate natural light, the tank looks more alive. Sadly I don't think my live plants will do the best with this type of light but its to early to tell. I can get plants that survive on lower light anyways :) buy this light, LEDs last forever and they look natural!

I simply love this light. I have a corner bow tank, so the leg extensions didn't work for me, but they are removable. Very little heat, low wattage, and the moon lights look spectacular.

I have a 60 Gallon freshwater aquarium with 6 Oscars and they love this light! The heat of my old Current USA Nova lights coupled with the heat of the Summer was bringing my tank temperature up to high for comfort. I knew I either had to buy a chiller (too expensive both for the chiller and the extra energy consumption required to run the darn thing) so I found the Marineland LED Double Bright light fixture and I knew this was my solution. Not only was the LED light way cheaper on PetMountain than my local store but the low energy consumption would also lower my monthly energy bill. This was a no brainer since it will pay for itself within the first year! I set it up in 1 minute and plugged it in and it looks fantastic!

On February 26, 2011:
This light works great. Will definitely get another one.

I've used this product in the past and have had no problems with it. Petmountain had the best price I found on line.

I ordered two of these for my two 29 and 20L and am very pleased. The light output is great and heat produced is almost none (heat in FL is a bad thing)! Easy to setup over a glass canopy. Just wish it had two power cords to allow a timer to switch from day to night lighting.

I purchased the 24 LED version of this light (the biggest one they sell) ABSOLUTELY AWESOME!! Adds really vibrant color to my tank, Very bright! I do agree with people who suggest Marineland put the blue LEDS on a separate power-supply so you can put them on a separate timer for night time, but my fish can survive without an automatic night light until then. I can push the button to make my tank blue at night, no biggie!

Works well with my saltwater tank.

On October 28, 2010:
The best value I found. It's a great light. I have a 75gl hex tank and this is what I needed. I would recommend this anytime.

This fixture would be an ideal choice for a fish only aquarium display due to it's sleek design, low power consumption, and no need for bulb replacement. The downside is that for a freshwater planted or saltwater coral tank this light is simply not enough. On the freshwater side you can definitely grow low light plants like anubias, java fern, crypts, etc. but I would not attempt anything more requiring. I would also recommend buying the biggest size that fits on your aquarium as this increases the amount of LEDs and makes the tank a bit brighter. Pros -low operating cost -sleek, low profile design -"shimmer" effect Cons -Low light output (suitable for fish only though) -switch between "day" and "night" is manual and cannot be used with a timer

These are the greatest lights ever they will pay for them selves in no time
