10 Best T5 Grow Lights Choices of 2024

The purpose of T5 grow lights is to provide a high-output fluorescent light source ideal for indoor gardening. They are typically used as primary or supplemental lighting in the growth of herbs, seedlings, and plants harvested in their vegetative state.

T5 grow lights offer the benefits of producing a greater amount of light compared to traditional fluorescents, making them perfect for indoor growing. They also aid in giving seedlings a flying start, being superior to natural light from a window for this purpose.

When choosing the best T5 grow light, it’s important to consider the size of your space, as most sources recommend them for small spaces. Another key consideration is the light’s intended use, such as for growing microgreens, seedlings, or plants in their vegetative state.

Choosing bulbs and fixtures largely depends on personal preference and specific gardening needs. For example, T5 grow room light fixtures might be more suitable for a larger indoor garden 3×3, 4×4 ft), while bulbs could be ideal for smaller (2×2, 2×4 ft grow tents).

Specific features to consider for T5 grow lights used for seedlings, microgreens, herbs, leafy greens, etc., include the light’s output and spectrum. These features ensure that the light can effectively support the growth stages of these specific plants.

Listed below are the top selection lists of T5 grow lights for all types of indoor growing in 2024.

  • Hydrofarm Agrobrite grow light system is the best T5 light fixture. It’s the most durable and sturdy design to ensure longer working hours and rare bulb replacement.
  • Barrina grow lights are the best T5 grow light bulbs. The lights use a full spectrum to support all growing stages without frequent replacement. 
  • Moya std grow lights are the best T5 grow lights for seedlings. They offer the soft blues for growing seedlings and more intensive rangers for vegetation. 
  • Hydro Plant grow lights are the best T5 grow lights for microgreens. The bulbs use an intense green color for chlorophyll and are ideal for indoor growers. 

1. Barrina Grow Lights – Best for maximum control of the light fixture

How do you choose the best T5 grow light?

To choose the T5 grow light, consider 6 factors: size and number of tubes, wattage, light spectrum, build quality and durability, energy efficiency, and price.

6 factors to choose the best T5 grow light

Size and number of tubes: The size determines how much area the light covers, and the number of tubes affects the overall brightness and intensity of the light. Consider a larger fixture with more tubes if you have a larger growing area. For instance, for a 4×4 grow tent, it’s suggested to use two 4-bulb T5 lights. For a 2×2 grow room, use a single 4-bulb T5 grow light. For a 6×6 grow tent, you need 5-7 4-bulb T5 grow lights. 

Wattage: Wattage measures how much energy the T5 light uses. Higher-wattage lights are generally brighter and produce more heat. You need 30-40 wattage per square foot of the canopy area. For a 2×2 grow tent, you need a 24-watt bulb. For a 4×4 grow tent, you need 385 watts of T5 grow light; for a 6×6 grow tent, you need 864 watts of T5 grow light. 

Light spectrum: Most T5 lights come in full-spectrum variants, meaning they cover all the light spectrum necessary for plants. However, some specialized models MarsHydro, T5pcs, etc.) may focus on certain parts of the spectrum, like blue (for vegetative growth) or red (for flowering).

Build quality and durability: Look for aluminum or steel fixtures, which are the most durable and have a prolonged lifespan. Such fixtures cannot be damaged so soon, regardless of the lighting conditions. 

Energy efficiency: Look for specific brands of T5 grow lights to save energy costs. For instance, Hydrofarm FLT44 as they use only 216 watts of actual power and is good for 4×2 grow tents. Another option is Barrina T5 grow lights, which provide 8×20 watts and are equivalent to 1000 watts. They are good options for 2×2, 4×4, 6×6, and 8×8 tents.

Price: Search for the best quality of T5 grow lights, given their price. For example, Barrina T5 is energy-efficient and costs around $40, while Hydro Planet lights are more expensive (around $90), but they offer a shorter lifespan and need extra ventilation. So choose the price corresponding to the quality. 

What is the best T5 light fixture?

The best T5 light fixture must provide wide coverage and minimal heat for indoor plants. It also must be durable and solid enough to ensure the best working conditions and work for an extended time without any damage. 

The best T5 light fixture is the Hydrofarm Agrobrite FLT24 T5 Fluorescent, 2 Foot, 4 Tube Grow Light System. Thanks to its German aluminum design and powder-coated finish, the grow light fixture lasts for an extended period and supports higher light temperatures. Its lifespan also adds to its durability. It’s also good for a higher heat output. 

What are the best T5 LED grow light bulbs?

The best T5 LED grow lights must ensure gentle but effective lights that HID lights cannot provide. They also ensure the best control and adjustable settings for optimal growth and cover all plant stages. 

The best T5 LED grow light bulbs are the Barrina Grow Lights. The Barrina grow lights offer maximum control of the light fixture, and you can adjust the lights for the healthy growth of the indoor vegetation with blue and red colors for vegetative and flowering stages. 

What is the best T5 grow light for seedlings?

The T5 lights help seedlings grow indoors as they can be placed inches away from the seedlings growing indoors and still receive the necessary amount of light for photosynthesis at a safe temperature. 

The best T5 grow light for seedlings is the Moya std White Grow Light Strips for Indoor Plants. The grow lights use the timer to set the working mechanism for 3, 6, and 12 hours, and five adjustable brightness modes keep the lights optimal. You can use softer lights for seedlings and flowers, while intense light is adjustable for vegetative stages. 

What is the best T5 grow light for microgreens?

T5 grow lights are commonly used to cultivate microgreens due to their efficiency, the quality of light they produce, and their ability to be placed close to the plants without causing heat damage.

The best T5 grow light for microgreens is the HYDRO PLANET T5 Grow Light. The consistent, bright light ensures optimal growth in all three stages, and they also offer sufficient green color to keep the microgreens healthy and optimal.

Are T5 bulbs cost-effective?

T5 bulbs are often considered cost-effective, especially compared to other lighting types, such as T8 or T12 lamps. They have a higher luminous efficacy, which indicates how much light a lamp generates from the energy it consumes. T5 fluorescent lamps have a higher luminous efficacy than T8 or T12 lamps, making them more efficient and, thus, more cost-effective in terms of energy costs.

T5 bulbs also have a longer lifespan, contributing to their cost-effectiveness. T5 fluorescent lamps were once the most energy-efficient option for tube lamps on the market, saving around 50% of energy costs, and their service life is several years.

What is the difference between T5 and T8 grow lights?

T5 grow lights have a diameter of five-eighths of an inch, making them thinner than T8 bulbs, which have a diameter of one inch or eight-eighths. T5 lights have higher light density, 1.5-2 times that of a T8 bulb with the same power. 

T5 grow lights are brighter for every watt of energy, and their output is more robust than the T8. However, T8 lights are approximately 40% smaller than T5 lights, which can make them a better choice for smaller indoor gardens. 

T5 grow lights are more suitable for high-light plants such as tomatoes, peppers, and cannabis. In contrast, T8 grow lights are better for plants with lower light requirements (spinach, herbs, lettuce).

While T5 bulbs may be more efficient, they are also more expensive upfront than T8 bulbs. However, their long-term savings from reduced energy consumption make them a more cost-effective choice.

What kind of plants can you grow with T5 grow lights?

With T5 grow plants, you can grow cannabis, spices, vegetables, microgreens, and fragile plants such as seedlings and herbs. 

Spices such as basil are grown under T5 grow lights. They don’t require much light, making them ideal for this indoor gardening setup.

T5 fluorescent lights are used to grow cannabis plants from seed to harvest. However, they are not the best choice for the flowering stage unless additional lighting is provided.

Some vegetables like lettuces and microgreens thrive under T5 grow lights. T5 grow lights provide a gentle yet effective light ideal for fragile plants like seedlings and herbs.

How far do I hang T5 lights from plants?

For young seedlings, the light should be closer so they can receive enough light without stretching too much. Generally, T5 lights should be about 6-8 inches away from seedlings.

As the plants mature, you can increase the distance to prevent burning. During the vegetative stage, keep the lights approximately 8-12 inches from the plants’ tops.

The plants will need more intense light during the flowering or fruiting stage. However, keep the lights around 12-18 inches away from the plants to avoid light burn.

How long do T5 grow lights last?

T5 bulbs generally last about 20,000 hours. Considering the usual daily light cycles of 8-12 hours, the expected lifespan of T5 bulbs ranges from 9 to 12 months. If it’s been over a year since you last replaced your bulb, it’s time for a new one.

You know it’s time for a change when your bulb is dimmable, changes its color spectrum, causes reduced plant growth, and when your plant is flickering or shows no light at all.
