Buying Guide

Woah, that was a lot of info at one go. But if you’re reading this, then you might be still confused about what to buy. Well, that is totally understandable.

Plus, we’re here to have your back, my friends. That’s why we compiled a list of things you need to be aware of before buying a T5 Bulb for the coral lives.

Color of The Bulbs

The first thing to look into is the color of the bulb. Yep, they come in all the spectrum of colors, still be so you need to make the right choice here. Now, we know that you’ll want to play with the colors to make the aquarium more lovely.

However, to make the aquarium optimum for coral growth, you can engage with all the colors of the spectrum. That means you need a hint of red, orange, yellow, green, violet, indigo, and blue.

But the main focus should be on blue. You see, they encourage the growth of the coral reef.

Fun fact- we, humans, require white color for our growth.

Number of Bulbs Your Need

Another thing you need to decide on is the number of bulbs you’ll get. You see, there are typically two channels in the fixture. One channel supports exactly 2 bulbs.

But the other one can support 4, 6, or even 8 bulbs. The first chamber is used to control the color during dawn time. The others are used for other times.

So, you need to check your fixture and see how many bulbs it requires. After that, you know how many to get. Simple right?

Position of The Bulbs

Next up, you need to figure out the position of the bulbs. You know, you won’t work with simply one bulb, right?

You’ll have to buy a few of them to fill the channels in the fixture. Now, to save a few bucks, you can buy the premium ones and put them in the middle, where they will get more active space.

And use the remaining ones for the other channels. This way, your coral reef will get more premium quality light to grow on. Trust us; you’ll thank us later.

The Temperature of The Bulbs

Moving on, the temperature of the bulbs plays a significant role as well. You see, each bulb emits a different amount of heat. Although the T5 bulbs are known to not emit too much, they can be a bit too intense at times.

Most of the time, the T5 bulbs have a 6500 Kelvin temperature. But those are the best ones for the growth of coral reefs. But, if you want to save a few bucks, you can buy the ones that emit 3000K. They work too.

Matching Fixture Size

Another important criterion to pay heed to is the size of the bulbs. Now, the diameter of all the T5 bulls is 5/8-Inch, but their vertical size varies. So, that makes the decision a bit tricky.

You see, you need to find the right size that goes in your fixture. Otherwise, the bulb won’t fit in, and it won’t be able to do its job. And in the end, you’ll have to re-order the whole thing again.

Hence, if you don’t want to go through the hassle, we suggest that you take a look at the size you want to begin with. It’ll save a ton of extra work.

Control Over the Lights

Lastly, try to look for lights that you can control of your own will. This will give you the power to turn the desired lights on separately. By that, we mean you won’t have one switch that controls all the lights in the fixture.

You’ll be able to play with the lights that you want. And they will listen to your words.

Optimum Usage Time: How Much Do You Need Exactly?

Now, you don’t actually have to keep the lights on all day long. Even those hard-working bulbs need some break from time to time. But you do want longer hours so that they can fully grow.

For this, you need to give the plants at least 9 hours of bulb time. Now, this is the right amount that will allow the coral reefs to fully grow. At the same time, it’ll ensure that the bulb works for a longer period of time.

By the way, the T5 bulbs have a lifetime of more than 20,000 hours. So, you can count on the bulbs to last for ages to come.

FAQs

Question: How much light do corals need a day?

Answer: The corals need at least 9 to 10 hours of light throughout the day to grow properly. Now, this can be either sunlight or artificial lights like T5 bulbs. Otherwise, they might even wither away or come to a stop in growth.

Question: Is T5 lighting good for corals?

Answer: The pros say that light that T5 emits doesn’t actually match the halide level needed by corals. But they still work for coral growth.

Question: How often should I change my T5 bulbs?

Answer: Now, if you follow our advice and let the bulb run for 9 hours a day it’ll fully grow. And it’ll last for 9 to 12 years. So, after that, you can change the bulbs and get some new ones for your reef tank.

Question: Do T5 bulbs get hot?

Answer: Yes, T5 bulbs do get hot from time to time. This is because they have a small diameter that emits light. Especially the ends. They have cathodes that tend to heat up the bulbs
