Barrina Grow Lights (June 2023)

The Barrina 20W T5 LED Grow Light Strip is a great option for small-sized (up to 1 foot tall) tropical indoor plants, succulents and cacti. The light is full-spectrum (not purple). It will provide good growth for your indoor plants and you won’t make a mistake if you decide to buy it. However, Dommia shelf light is a better choice – it provides the same benefits, covers a slightly larger area and is more affordable.

There are 3 ways to install the Barrina T5 LED grow light strips. You can use metal screw-in connectors, zip ties, or double-sided tape to mount the 4 strips to the shelf. The double-sided tape is the easiest and most elegant way to install this plant grow light.

To use Barrina T5 LED grow light strips on tropical plants, place them 6 to 8 inches from the plants, and keep them on between 8 and 12 hours per day. For succulents and cacti, keep them 3 to 5 inches from your plants, for 12 to 16 hours per day. Use 2 light strips for each plant or set of plants, to get a sufficient amount of light.

Since the light doesn’t come with a built-in timer, you can purchase a separate timer, to set the light to automatically go on and off at certain intervals.

With Barrina T5 LED grow light strips you can grow small (less than 1 foot tall) tropical plants, succulents and cacti. You can also grow medium-sized (between 1 and 3 feet tall) and large (over 3 feet tall) tropical plants that require low or medium light.

This light is not strong enough to grow large bright-light tropical plants nor large succulents and cacti. To grow large bright-light tropical plants and large succulents and cacti a better option is Sansi 36W grow light or Rousseau pendant grow light.

If you are not sure which plants are bright-light plants, take a look at my table of direct and indirect light requirements by plant. You will see which plants are low light tolerant, which have medium light requirements and which have bright light requirements.

Barrina 20W thin grow light panel is a great option for small-sized (up to 1 foot tall) tropical indoor plants, succulents and cacti. The light can be full-spectrum, or purple. It will provide good growth for your indoor plants and you won’t make a mistake if you decide to buy it. However, Dommia shelf light is a better choice – it provides the same benefits, and is much more affordable.

Connect the two panels together. Then connect the panels with the timer power cord and the AC/DC adapter. Add 8 plastic snap-in adhesives to the 4 corners of each grow light panel. Remove the paper from the snap-in adhesive and press the grow light panel under the shelf, in the desired position. Plug in, set the timer and you’re done.

To use Barrina thin grow light panel on your tropical plants, place it 6 to 8 inches from the plants, and keep it on between 8 and 12 hours per day. For succulents and cacti, keep it 3 to 5 inches from your plants, for 12 to 16 hours per day, as shown in the diagram below.

You can set the light to automatically go on and off with the built-in timer. Since the built-in timer only allows settings for 3, 6, and 12 hours, if you want to have more control over the time schedule, you can purchase a separate timer.

With Barrina grow light panel you can grow small (less than 1 foot tall) tropical plants, succulents and cacti. You can also grow medium-sized (less than 3 feet tall) and large (over 3 feet tall) tropical plants that require low or medium light, but in that case you will have to hang the light from the ceiling.

This light is not strong enough to grow large bright-light tropical plants nor large succulents and cacti. To grow large bright-light tropical plants and large succulents and cacti a better option is Sansi 36W grow light or Rousseau pendant grow light.

The Barrina 25W LED Grow Light Bulb is a full spectrum grow light with a built-in shade, timer, and a cable, making it a convenient standalone lighting solution for small to medium-sized indoor plants. Although it requires drilling holes for installation and cannot be used with existing floor or desk lamps, it offers an effective lighting solution for plants under 3 feet tall. For those seeking a more powerful option, the Sansi 36W or Rousseau grow light are recommended.

The Barrina 25W LED Grow Light Bulb is easy to install and operate. Drill a hole in the ceiling and use the provided expansion bolts and cord grips to secure the 16.4ft power cable. Simply plug in the pendant grow light bulb and set the timer. The timer offers three functions, 4H/9H/14H, and can be set to repeat daily. A detailed installation manual is included in the package.

If you are not comfortable with drilling a hole, you can use sticky ceiling hooks. They can carry a heavy load.

To use Barrina 25W LED grow light bulb, place it 1 foot high from the top of your indoor plants and keep the light on for around 8 hours for low light tolerant plants and medium light plants and around 16 hours for bright light plants. You can set the light to go on and off with the built-in timer automatically. If you want more control over the time schedule, you can purchase a separate timer.

If your indoor plant is getting some natural light, you can reduce the length of exposure to the grow light, or you can increase the distance between the grow light and the plant.

Barrina 25W grow light covers a relatively small surface area of 1 by 1 feet. Grow lights like this one put out light from a small, narrow area. Light intensity drops exponentially with distance, so the light that reaches the edge of the coverage area loses a lot of its intensity. This means not a lot of light reaches the plants at the edge of the coverage area, as you can see in the images below.

With Barrina 25W LED grow light you can grow small (under 1 foot tall) to medium-sized (between 1 and 3 feet tall) tropical plants as well as small to medium-sized succulents and cacti.

The Barrina Height Adjustable Lamp is a great grow light for small (less than 1 foot tall) to medium-sized (1 to 3 feet tall) tropical plants and succulents. It is easy to set up and comes with an extendable rod that allows you to adjust the height of the grow light. However, it is not suitable for large tropical plants or large succulents and cacti, except for large low light tolerant tropical plants.

If you are unsure which plants are low light-tolerant, take a look at my table of direct and indirect light requirements by plant.

When compared to the popular Halo grow lights, Barrina Height Adjustable Lamp is a much better alternative.

To install the Barrina height adjustable lamp, connect the grow light panel to the extendable rod, connect the rod to the plastic stick, and insert the stick into the desired pot. Set the grow light at the desired height and that’s all. The height-adjustable lamp is truly one of the easiest grow lights to set up.

I have been growing house plants (both tropical plants and succulents) under grow lights for over 10 years. I also had a carnivorous plant business where I grew hundreds of plants under grow lights for several years. All of this helped me learn about different types of grow lights (LED grow lights, fluorescent lights, fluorescent bulbs, full-spectrum lighting…), how to measure their brightness, how to determine the proper distance between the light and the plant, and other intricacies of growing indoor plants under grow lights.

I identified the key decision-making factors for grow lights and I tested and conducted measurement of all Barrina grow lights in great detail, by using a PAR meter, to determine how they measure in each of the factors, and which plants they are best for, and what are the best alternatives to Barrina grow lights. I measured the light output of each grow light. The key decision-making factors were: 1) brightness 2) design 3) price 4) glare 5) unique features that set it apart from the competition 6) warranty 7) ease of setup

Barrina grow lights provide a variety of choices to meet the needs of indoor plant enthusiasts, accommodating different plant sizes and lighting requirements. The light output is good. These lights emit full-spectrum illumination, promoting the well-being of small to medium-sized tropical plants, succulents, and cacti. Although they may not be the cheapest option in comparison to certain alternatives, Barrina grow lights offer dependable and user-friendly solutions for indoor gardening.
