From what I personally have observed combined with the opinions of other aquarium professionals is the use of gray nylon filter placed over standard daylights (T2, T5, T8 CFL, etc.) can work as a moonlight; even low level "white" lights such as nightlight bulbs, or even the Rio Mini Sun LED lights can work just fine for this since this has shown to be a more of a low level light issue and timing issue.
This LED light has been specially designed for marine fish aquarium and especially reef tanks with live corals

I just got a deebow led light that is 5550 to 6650k not sure about the lumen 120cm would that be ok for an 18 1/2 inch depth aquarium..

Are LED aquarium lights what we have in store for the future of aquarium lighting systems? Prices are still very high and they will need to drop significantly in price before more hobbyists will transition to them. The prices are coming down, just not fast enough. They offer many advantages over previously mentioned lights. Some of the advantages of LED lights over convential Fluorescents and metal halides include:Fish rely on a regular day/night cycle for optimum health, however brightness is less important and too much light can cause algae growth. Live plants, on the other hand, need strong light (which is different than brightness level) and a broader spectrum for photosynthesis. Certain fluorescent lamps and LED bars can enhance the colors in fish and the overall appearance of your aquarium. Many of the light fixtures being sold now include moon lights which are LEDs. So we're starting to see them more often, but even though these LED aquarium lights are very promising we are probably still a few years away from using them as the primary light source on most home aquariums. Check out the ecotech radion LED lighting fixture which is getting really good reviews from hobbyists. I run these over my 120 gallon reef tank now and reviewed them for the magazine. Check out the for more information.Get the ultimate DIY book:

These are not a practical choice for a planted aquarium. They are no where near as strong as what would be needed. I mention their ideal use in the video and also mention they would not be useful on a planted tank or reef tank.

Each LED is not even 1 watt. they are closer to 0.10 watts.

A planted tank needs around 30 watts per square foot of tank.

EXAMPLE: So for an 4 foot long 55 gallon planted aquarium (4 square feet) we need 120 watts of LED lighing power.

Even if we buy the 60 LED/meter light strip, that would only be around 8 watts of power.

MEANING you will need to buy 15 of these strips to MAYBE match what a good LED light fixture can do. (15 strips = $345)

You are better off buying a proper planted tank LED light or building the more powerful LED system i have shown in a previous video.Incandescent lighting is still used in some aquariums, but more economical and visually pleasing options like fluorescent and LED are the norm. Fluorescent lighting is cooler, brighter and uses less electricity than incandescent. It is a common type of aquarium lighting, although LED is surpassing it in popularity. For peak performance, replace incandescent and fluorescent lamps annually. LED lights are the most economical and energy efficient and offer a wider range of lighting options.If you have not heard about the benefits of using LED lighting for you aquarium then you are definitely in the right place. LED lighting is becoming one of the most popular choices for aquarium hobbyists. Aquarium LED lighting can be used in marine, reef and freshwater aquariums.
