How to Choose the Best T5 Grow Lights?

Now that indoor gardening is getting more common, manufacturers are starting to introduce more product choices for consumers. Since one of the most important things that plants need is sunlight, T5 grow lights were introduced to the market. T5 grow lights are the latest technological innovation that is designed as an alternative solution to natural sunlight. Thus, indoor plants can still get the right amount of light they need for photosynthesis.

But unlike LEDs and HPS bulbs, T5 (tubular lamps with 5 inches for 5/8-inch diameter) grow lights are less expensive. It’s also cooler than HPS bulbs which normally contain more space. So, here are some things to remember when choosing the best T5 grow lights:

Some are available in 1 to 2 bulb set up while others are available in 8 to 12 set up.

  • Bulbs

T5 grow lights come with interchangeable bulbs that have various energy and color temperatures. Some lamps work best on vegetative stages while others work best only on flowering stages. You might also encounter NO (Normal Output), HO (High Output), and VHO (Very High Output) bulbs. In this case, it’s better to go for HO since it offers the best of both worlds. This output can already provide high brightness to your indoor plants.

Regardless of how long or how many bulbs you need to ensure your plants’ growth, it should always be energy-efficient. The more you can save on your electricity bills, the better even if you opt for the larger sizes.


  • Is it practical to invest in T5 grow lights?

Each tubular lamp produces efficient light to plants especially from those growing seedlings until the harvest time comes. Compared with HPS and LED grow lights, T5 lights are much cheaper. Since it also produces less heat than HPS bulbs, it can provide more usable light for your plants.

  • What is the best size of T5 grow light fixture to buy?

T5 grow lights may vary in lengths but its standard thickness will always be 5/8 inches. Most T5 grow light users purchase it in 2 and 4 ft. depending on their growing area. Thus, you would need a bigger fixture the more and longer tube you use. But to be safe, we recommend opting for the biggest size that your grow room can accommodate. This way, you can customize the light output in your fixture for each type of plants you have under it.

After all, most modern fixtures nowadays provide a separate switch for each bulb for additional convenience. The bigger fixture you can fit the better to accommodate more plants regardless of the amount of light they need.

  • What are the bulb temperatures of T5 grow lights?

T5 bulbs have various temperatures but the 2 main temperatures that matter most in plants’ growth stages are 6,500K and 3,000K. 3000K bulbs can help your plants produce flowers and fruits. Meanwhile, the 6,500K bulbs are the most popular type that can help your plants in the harvest period. This is also the most practical choice for those with micro greens and seedlings to boost their growth potential.

  • What re reflectors in T5 grow lights?

Reflectors boost T5 bulbs’ efficiency by increasing its focus to plants. It is available in a rectangular reflector and gullwing style. Rectangular reflectors are designed to be placed closer to plants for better coverage. In contrast, the gullwing style reflectors are designed to be placed on a higher position to redirect its light back.


Almost all kinds of lighting bulbs can be used to ensure the growth of indoor plants. However, only a few of them can be considered as at par in performance. The number of choices can be a little overwhelming too since there are lots of brands to choose from. Thus, going over guides like this can help you narrow down your search.
