8 Best T5 Grow Lights of 2026
Eight LED T5 grow light sets compared on bar length and count, listed power, spectrum, controls, moisture rating, and linking, with who should skip each.
By Ethan Cole
Updated October 23, 2026
T5 grow lights are slim LED bars about 5/8 inch across, the same diameter as the T5 fluorescent tubes they replaced. The LED versions here are integrated fixtures: the LEDs, housing, and power cord come as one piece, and most link end to end so one outlet can run a whole shelf or rack.
This guide covers LED T5 bars from 1 to 2 feet long. For longer tubes see 4 ft grow lights, for 2-foot bars of every style see 2 ft grow lights, for Barrina’s full line see Barrina grow lights, and for every bar style see grow light bars.

Top 3 T5 Grow Lights Reviewed
#1 Barrina T5 Grow Lights, 2 ft, 5000K (8 Pack): Best Overall
Why We Picked It
Barrina’s 2-foot T5 eight-pack leads this guide with a 4.7-star average across more than 6,500 ratings for its listing family. Eight 2-foot bars cover two full seed-starting shelves, or four shelves with two bars each, from a single order.
Each bar has its own on/off switch, and Barrina lists linking up to 16 bars in a series. The set totals 80 watts across 400 LEDs in 5000K daylight white. Mounting is by clips, cable ties, and double-sided tape; Barrina notes these bars are not magnetic and should not go on dusty or uncured surfaces. The warranty is 2 years.
Key Specifications
- Pack: 8 bars, 2 ft each
- Power: 10W per bar, 80W total, per Barrina
- LEDs: 400 in total
- Color: 5000K white
- Linking: up to 16 bars, 4 power cords and 7 link cords included
- Warranty: 2 years
| Pros | Cons |
|---|---|
|
|
Things to Consider
With no timer built in, plan on a plug-in outlet timer. One timer can run a whole linked chain as long as you stay within Barrina’s link limit.
Best For
Seed-starting racks and plant shelves that are at least 2 ft wide.
Skip It If
Skip it if you want a built-in timer and dimmer; the VIVOSUN set below has both.
Check current pricing and availability for the Barrina T5 Grow Lights, 2 ft, 5000K (8 Pack).
#2 Barrina T5 Grow Lights, 1 ft, 5000K (4 Pack): Best for Small Shelves
Why We Picked It
The 1-foot Barrina four-pack has the largest rating base in this guide, more than 7,000 ratings at 4.6 stars across its family. It is the smallest way into Barrina’s T5 system: four short bars for a bookcase, a windowsill shelf, or a narrow cabinet.
The bars use 96 LEDs and 20 watts in total, each with its own switch. They link up to 16 in a series with the included cords, so you can add more 1-foot or 2-foot bars from the same line later.
Key Specifications
- Pack: 4 bars, 1 ft each
- Power: 5W per bar, 20W total, per Barrina
- LEDs: 96 in total
- Color: 5000K white
- Linking: up to 16 bars, 2 power cords and 3 link cords included
- Mounting: clips, tape, cable ties (not magnetic)
| Pros | Cons |
|---|---|
|
|
Things to Consider
Four 1-foot bars cover about the same length as two 2-foot bars, with twice the connections. On a wide shelf, the 2-foot pack above is simpler.
Best For
Bookcases, cabinets, and shelves 12 to 20 inches wide.
Skip It If
Skip it if you are lighting a 4 ft rack; see 4 ft grow lights.
Check current pricing and availability for the Barrina T5 Grow Lights, 1 ft, 5000K (4 Pack).
#3 Bokeedo T5 Grow Lights with Reflectors, 10W (2 Pack): Best with Reflectors
Why We Picked It
Bokeedo’s two-tube set scores 4.6 stars on about 500 ratings. It is the only T5 set here with V-shaped aluminum reflectors on every tube, which aim the light down instead of letting it spill across the room.
Each 1.4 ft tube is 10 watts, and Bokeedo lists more than 1,900 lumens for the pair and publishes a PPFD chart in its listing images. The spectrum combines 3000K, 6000K, and 660nm red chips. There is no dimmer. Bokeedo gives a 12-month warranty and a 30-day return guarantee.
Key Specifications
- Pack: 2 tubes, 1.4 ft each
- Power: 10W per tube, 20W total
- Published output: 1,900+ lm for the pair
- Spectrum: 3000K, 6000K, and 660nm red
- Reflector: V-shaped aluminum
- Warranty: 12 months
| Pros | Cons |
|---|---|
|
|
Things to Consider
Reflectors make the light below the tubes stronger but darker to the sides, so plants just outside the tray get less light.
Best For
One seed tray or a small herb shelf where you want light kept off the walls.
Skip It If
Skip it if you want to cover more than one shelf from one box.
Check current pricing and availability for the Bokeedo T5 Grow Lights with Reflectors, 10W (2 Pack).
How to Choose T5 Grow Lights
LED T5 or Fluorescent T5
Every product here is an LED fixture. If you already own a fluorescent T5 fixture, you need replacement tubes made for it, not these bars.
Length and Count
1 ft bars fit bookcases; 2 ft bars fit a standard 10 x 20 inch seed tray lengthwise. Two to four bars side by side cover a tray more evenly than one.
Controls
Most T5 bars have an on/off switch only. VIVOSUN builds in a timer and dimmer, and GLOWRIUM adds app control. Otherwise use an outlet timer.
Moisture Rating
Barrina, Bokeedo, and VIVOSUN list no water rating. Maygrove lists IP63 and Spider Farmer IP65, better suited to greenhouses and humid closets. No rating means keep the bars away from water.
Linking Limits
Each maker sets a maximum number of bars per chain (16 for Barrina, 18 on 120V for Spider Farmer). Stay under it, and do not mix brands on one chain.
How We Evaluate T5 Grow Lights
We did not grow plants under these lights. We compared manufacturer specifications and Amazon listing details and ranked the products by the WikiHomeLED Score, which adjusts the Amazon star rating for the number of ratings (ratings checked October 24, 2026). To qualify, a product had to be an LED T5 style bar with at least 20 ratings, one listing per product family. Fluorescent T5 bulbs and fixtures were excluded. The full method is on our How We Review page.
Frequently Asked Questions
What does T5 mean on an LED grow light?
It describes the tube diameter, 5/8 inch. On LED grow lights the name is a size and style description; these bars do not use fluorescent T5 bulbs.
How many T5 bars do I need for a seed tray?
For a standard 10 x 20 inch tray, two to four 2 ft bars side by side are a common setup. Follow the maker’s height guidance for seedlings.
Are LED T5 grow lights better than fluorescent T5?
LED bars use less power for similar light and run cooler. Fluorescent T5 HO tubes are still sold, but they need a ballast fixture and replacement tubes over time.
Can I mount T5 bars with magnets?
Some can. Spider Farmer includes magnets; Barrina’s 1 ft black-cover line includes magnetic strips, but the 1 ft and 2 ft white sets in this guide are not magnetic.
Final Verdict
The Barrina 2 ft eight-pack is the T5 set to start with: the top score, enough bars for a full rack, and daylight-white light. For a narrow bookcase, the Barrina 1 ft four-pack uses the same system. Pick the VIVOSUN set if you want a timer and dimmer built in, and Spider Farmer or Maygrove if the bars will live in a humid greenhouse.
