So, what are T5 Grow Lights?

Best T5 Grow Light

Grow rooms and grow tents are some of the terms gradually increasing in popularity in contemporary gardening literature. Indoor gardening is the new way of growing crops successfully using a controlled environment. But where do the T5 lights come in?

The T5s are fluorescent lights, and the term ‘T5’ denotes the size. Typically, the letter ‘T’ means tubular while the ‘5’ is the diameter in inches. Clearer now?

Unlike their width, the T5’s length varies and can either be 2 of 5ft. Depending on the fixtures, their weight can be between 10 and 30lbs. In the majority cases, the ballast is usually a part of the T5 fixtures, and so you may not need to worry about where you are going to place the light.

It may sound as if the T5s are similar to fluorescent bulbs. Are there any similarities? Are they the same thing?

Basically, the standard CFLs are made explicitly for human lighting and so come without the necessary features to function efficiently as grow lights. You would need to fix the light too close to the plants for any effect on the plants. However, they quickly run hot, and it is not strange if you woke up one day to find burned leaves.

On the other hand, the T5 lights are made for the sole purpose of use in the grow rooms.

So Why Would I Need the T5 Lights?

Best T5 Grow Light

Well, we may not talk about energy efficiency as there are LEDs for that. But we can talk about cost. T5s are way cheaper than the LEDs, which is music to the ears of those starting out in indoor gardening.

But just because they cannot match their counterparts, the LEDs doesn’t mean that they are electricity spendthrifts. As a matter fact, T5s don’t use that much electricity to eat on your bottom line.

They are also quite cool, and chances of having scorched plants are minimal. You only need to suspend them a few inches closer to the plants – this may also mean efficient use of light based on the proximity of the light.

The T5s are also ideal for raising the plants through the vegetative stage. And unlike the high-pressure sodium lights, the T5s will not scorch the plants – pretty cool, literally! It also means that you are free to use a shorter tent – and you know what that means?

Yes, minimal expense on fixtures and reduced growing spacing. If you live in a warm climate, then there’s no argument about their suitability as they run cooler than other lights.

But do the T5s have a proven record of efficiency given all the fuss about LEDs? The simple answer is that T5s have been part of successful weed growing establishments for a long time. It is therefore not unusual to come across staked shelves of seedling thriving under these fluorescents.

Are there any Shortcomings Associated with the T5 Lights?

Best T5 Grow Light

On their own, the T5 lights are not sufficient during the flowering stage. If anything, you will require the help of red spectrum lights to ensure a good harvest.

They also don’t last that long in comparison to the LEDs – their lifespan is about half that of LEDs. Another downside is on the requirement of ballast for them to function well.

What is this ballast? Well, this is a necessary fixture where T5s are concerned. The ballast help keep the fluorescent bulb from burning out as a result of drawing too much power. This fixture stabilizes the lights and prevents the flickers that would be harmful to the plants.

Things to Consider before you Purchase a T5 Grow Light

  • Accessories: before you settle on a choice, determine if it comes with all the necessary accessories to suit your needs. For example, is the cable length sufficient for your needs? Are the replacement bulbs easy to find?
  • Installation: it is wise to think about how you are going to install the lights. Is specialized help necessary? How much does it weigh?
  • Budget: for the gardeners more conscious about their bottom line, such issues as the cost of electricity are vital. You may need to compare how much you are going to save with T5s and with the LEDs, over time. The cost of the light and its fixtures are worth a deep thought.
  • Other Equipment: we mentioned that T5s are not adequate on their own. It is a good idea to think about the red spectrum lights in addition to purchasing the T5s for an all-around benefit to your plants.


T5 grow lights will nurture your plants to health through the growth stages. Any of the above products are good quality and will do their job sufficiently. However, you will agree with us that the biPower T5 4-Foot 4 Lamp is a product on a different level. But what makes it the best?

Well, it has a dual switch for proper control of the fixtures, daisy-chain link for connecting different fixtures and has a highly efficient reflector. This is one light that your plants will love.
