9 Best 4 ft Grow Lights of 2026
Nine 4-foot grow lights, mostly integrated T8 tubes, compared on tube count, listed wattage, light color, reflectors, water rating, and timers, with who should skip each.
By Ethan Cole
Updated October 23, 2026
Four-foot grow lights are the standard for full-size seed-starting racks and garage shelving, where shelves are 48 inches wide. Most are integrated T8 tubes: the LEDs, reflector, and housing come as one piece, and several tubes link from one outlet.
This guide covers 4-foot tubes and single 4-foot fixtures, including waterproof and timer models. For shorter shelves see 2 ft grow lights and T5 grow lights, for complete racks with lights see grow light shelves, and for every bar style see grow light bars.

#1 Barrina 4 ft T8 LED Grow Lights, 42W, Pinkish White (6 Pack): Best Overall
Why We Picked It
Barrina’s 4-foot T8 six-pack has the largest rating base of any grow light we compared, more than 13,000 ratings at 4.6 stars across the family. Six 4-foot tubes light a full 4 ft rack, three shelves with two tubes each or two shelves with three.
Each tube is an integrated 42-watt fixture with an aluminum body and a V-shaped reflector, so there is no ballast or separate bulb. Three power cords with switches and five 48-inch link cords come in the box, and up to six tubes link in a series. Barrina notes that its newer cords use a different connector from older tubes, so mixing generations needs its adapter cables.
Key Specifications
- Pack: 6 tubes, 4 ft each
- Power: 42W per tube, 252W total, per Barrina
- LEDs: 1,152 in total
- Color: pinkish white (red and blue rich)
- Reflector: aluminum V-shape
- Linking: up to 6 tubes; 3 power cords and 5 link cords included
| Pros | Cons |
|---|---|
|
|
Things to Consider
The pinkish color makes plants look purple-gray under the light. If you will see the rack every day, the white version just below uses the same tube.
Best For
Basement, garage, and closet seed-starting racks with 4 ft shelves.
Skip It If
Skip it if the rack is in a living room or office; pick the 5000K white version.

#2 Barrina 4 ft T8 LED Grow Lights, 5000K White (6 Pack): Best White Light
Why We Picked It
This is Barrina’s same 42-watt 4-foot T8 tube in 5000K daylight white. Its own listing family scores 4.7 stars on about 1,500 ratings, the highest average in this guide.
White light shows leaves in their real colors and is easier to work under, which matters when the rack sits in a room you use. The kit, reflector, link limit of six, and accessories match the pinkish version.
Key Specifications
- Pack: 6 tubes, 4 ft each
- Power: 42W per tube, 252W total, per Barrina
- LEDs: 1,152 in total
- Color: 5000K white
- Reflector: aluminum V-shape
- Includes: 3 power cords, 5 link cords (48 in), clips, tape, ties
| Pros | Cons |
|---|---|
|
|
Things to Consider
White and pinkish tubes from the same generation use the same connectors, so you can mix colors on one rack.
Best For
Racks in a spare room, kitchen, or office where you will see the light every day.
Skip It If
Skip it if your shelves are under 4 ft wide; see 2 ft grow lights.

#3 Sunco 4 ft LED Grow Lights, 80W (4 Pack): Best Warranty
Why We Picked It
Sunco’s four-pack scores 4.5 stars on more than 1,000 ratings. Each 4-foot fixture is listed at 80 watts and 4,000 lumens, nearly twice the wattage of a Barrina tube, so fewer fixtures can cover the same shelf.
The fixtures hang from the ceiling or mount flush, with a 5 ft plug-in cord and a 24-inch pull-chain switch, and up to four link together. Sunco is based in the US and lists a 3-year warranty, the longest among the 4-foot lights here.
Key Specifications
- Pack: 4 fixtures, 4 ft each
- Power: 80W each, per Sunco
- Published output: 4,000 lm each
- Switch: 24-inch pull chain
- Cord: 5 ft plug-in
- Warranty: 3 years
| Pros | Cons |
|---|---|
|
|
Things to Consider
At 80 watts each, four fixtures draw 320 watts. Check that the outlet and any power strip are rated for the total.
Best For
Garage or basement setups where you want fewer, stronger fixtures and a longer warranty.
Skip It If
Skip it if you want a low-profile tube for tight shelf spacing.
Check current pricing and availability for the Sunco 4 ft LED Grow Lights, 80W (4 Pack).
How to Choose 4 ft Grow Lights
Light Color
Pink or pinkish white tubes (Barrina, TYAGMAM, JESLED IP65) are common for basements. 5000K white tubes (Barrina white, Elaruslux, JESLED 5000K) look natural in a room and make it easier to spot pests and leaf problems.
Tubes per Shelf
On a 4 ft shelf about 18 inches deep, two tubes is a common minimum; three spreads light more evenly. Higher-wattage fixtures like Sunco can cover the same area with fewer pieces.
Moisture
Only JESLED’s waterproof tubes list IP65. The others list no water rating, so keep them clear of misting and watering, and never let connectors sit in a drip tray.
Timers
Elaruslux has a timer built in; every other set here needs an outlet timer. A single timer can switch a whole linked chain.
Power Draw
Add up the watts on each chain and outlet. Six 42 to 48-watt tubes draw about 250 to 290 watts; plug long runs into a grounded outlet, not a light-duty extension cord.
How We Evaluate 4 ft 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 a 4-foot LED grow light tube or fixture with at least 20 ratings, one listing per product family. Fluorescent tubes and shop lights were excluded. The full method is on our How We Review page.
Frequently Asked Questions
Can I use LED shop lights instead of 4 ft grow lights?
Many growers start seeds under bright white shop lights. Grow tubes add red-rich spectra, reflectors, and published grow figures, but a 5000K shop light can work for seedlings at close range.
Do T8 LED grow lights fit old fluorescent fixtures?
Not the integrated tubes here. They are self-contained fixtures with their own power cords and do not go into fluorescent sockets.
How high should 4 ft grow lights hang above seedlings?
Follow the maker’s guidance. Many growers start a few inches above seedlings and raise the tubes as plants grow or if leaves show bleaching.
How many 4 ft grow lights can I plug into one outlet?
Stay within each brand’s link limit (4 for Sunco, TYAGMAM, APICDOM, and BoostGro; 6 for Barrina and Elaruslux) and within the outlet’s rating.
Final Verdict
Barrina’s 4 ft T8 six-pack is the tube to start with: the largest rating base, a reflector on every tube, and enough tubes for a full rack. Choose the 5000K white version if the rack is somewhere you spend time. For a humid greenhouse, JESLED’s IP65 tubes are the only sealed option here, and Elaruslux is the pick if you want a timer built in.
