Top 3 LED Lights for Your Planted Aquarium And Guide

When it comes to lighting up the aquarium, you need to realize that it is not only about the light but about the growth of your plants as well.

Choosing from various products available in the market is never an easy option.

Led light for planted tank

The features, the price, the pros, the cons, and the other factors are something that we always try to take care of.

These are essential things that should be taken into consideration while purchasing anything.

The lights are one of the most important and expensive pieces of equipment for your aquarium. Lighting is so expensive, that some aquarists actually recommend you harness the energy of the sun, in a greenhouse, if you want to take your coral or plant operation commercial.

Lighting options for reef tank

Aquarium lighting has changed, quite a bit, over the last several years. For much of the recent reef-keeping past, metal halide lights were the gold standard. They may still be the gold standard, but two different lighting systems have come onto the scene to make a run at the gold.

High-output fluorescent and LED options can’t quite match the sheer intensity generated by a metal halide lamp, but they can still create intense, coral-growing light with a fraction of the energy cost.

As long as you have one of those three options (metal halide, T-5 fluorescent or high-intensity LED), you probably have the right amount of light to sustain coral growth.

There is some evidence that metal halide lights sustain more coral growth than either T-5s or LEDs, but that sustained growth comes along with a higher cost for electricity and the replacement of bulbs.

You may be surprised to see how quickly the energy and bulb costs can add up. If money is no object, and you are focused strictly on coral growth—then I recommend you purchase a metal halide light.

How much light is enough light for reef tank?

If we now all understand and agree that having the appropriate light is an important part of providing corals with what they need to grow, the next question on your mind may be, how much light is enough light?

I often see and hear reef hobbyists ask how many watts of light they need, how many hours a day do they need to run their lights, and what type of bulbs they should buy.

All of those things are important details, but the answer to those questions is usually, “it depends,” so before I attempt to answer those questions, let’s step back for a moment and look at a more important and less ambiguous way to think about the quality of the light you are providing to your corals.

What is the best light spectrum for plant growth?

The right spectrum is an essential factor for getting you the right type of output important for the growth of your plants.

LED light source that offers light within the entire visible variety will better meet the desires of the plant.

Photosynthetically Available Radiation (PAR)

PAR is one of the more important factors to consider when considering, comparing, or otherwise evaluating aquarium lighting. The term PAR is an abbreviation for a more scientific-sounding term: photosynthetically Active Radiation. You will convince your friends and family of your ‘fish nerd’ status if you drop that little nugget at dinner.

You may be thinking, ‘that’s great, you knew what PAR stands for, but what does it mean?’ Well, unfortunately, we have to dive a little deeper into geek-dom to explain it. If I could take you back to science class, you may remember that light is both a wave and a particle and that there are all sorts of ‘types of light,’ like infrared, visible, and ultraviolet.

Well, think of PAR (Photosynthetically Active Radiation as the type of light (radiation) that promotes (active) photosynthesis. The illustration above, from Wikipedia, shows the wavelengths of PAR. PAR, scientifically, delineates which light is available for photosynthesis. That is still a little nerdy for my liking—so here’s my simple-man’s takeaway.

Photosynthetic bacteria and plants take light energy and convert it into sugar through the process of photosynthesis. PAR is a way to categorize the possible ‘nutritional value’ of the light to your coral, clams, or algae. The higher the PAR value (which is measured by a PAR meter also known as a quantum light meter), the more energy is available for photosynthesis, and therefore the greater the potential for life-sustaining sugar to be created from light and CO2.

You can (and should) use a PAR meter to measure the ‘nutritional value’ of your aquarium light at various depths and locations in your tank, and use it to pick the best locations for your corals or plants.

Metal Halides, for example, generally produce strong PAR levels in a wide footprint, all the way to the bottom of even larger tanks, whereas LED lights tend to produce a narrower beam of light that loses intensity more quickly in deeper aquariums.

Over time, as light bulbs wear out, the PAR output decreases, so a PAR meter can be a helpful way of watching the drift to determine when it is time to change or upgrade your lights. PAR meters range in price, ease of use, and quality, but like most things in our hobby, the price has come down some now because of how easy it is to buy products from suppliers around the world on Amazon and eBay.
