4. Which four foot grow light should you choose?

The best 4 foot grow lights for wide plant shelves are linkable LED strips, while replacement T5 bulbs make sense if you already have a compatible fixture. The Barrina 4FT T8 set is our top pick for a multi-bar layout; APICDOM is a slim single fixture, and VIVOSUN is the bulb option.

Measure the shelf or propagation bench before choosing. Four-foot products vary in length, and the longest in this group measures 48.8 in.

How we chose these four foot grow lights

We compared the light source, fixture length, pack size, mounting choices and linking options against the needs of a wide shelf or propagation bench. Our score weighs specs, features and buyer feedback against what you're shopping for.

A light bar that matches your shelf can simplify coverage, but the number of bars matters too. For panel-style alternatives, compare Spider Farmer LED grow lights.

A multi-pack can cover more of a bench, while a replacement bulb only helps if your fixture accepts its base and length.

For a closer look at the two common light sources, read What Is the Difference Between LED and Fluorescent Grow Lights?. If you have a fluorescent fixture already, our guide to growing indoor plants under fluorescent lights covers the setup questions.

The best four foot grow lights for shelves and benches

The right 4 foot LED grow light depends on whether you need a complete fixture, several bars or replacement lamps. For shelf and pot setups in other formats, see SANSI grow light options.

These picks are listed from highest to lowest score.

VIVOSUN T5 Grow Light Bulbs 4Ft: Best for replacing T5 bulbs

9.7/10Our score

• 5-pack of 46 in fluorescent T5 bulbs
• 54 watts each
• 6500K cool white
• G5 base

These 46 in T5 bulbs suit a compatible fixture that needs replacement lamps. Check the fixture base and length before choosing them.

See it on Amazon

Pros

• Five bulbs in one pack
• 6500K cool white light
• G5 base

Cons

• Bulbs only, not a complete fixture
• Requires a compatible T5 fixture

VIVOSUN is the bulb pick for an existing T5 fixture, not a standalone grow light fixture. The pack contains five 46 in fluorescent bulbs with a G5 base, so confirm both details against your fixture before ordering.

Each bulb is rated at 54 watts and 6500K cool white. For how fluorescent fixtures differ, read fluorescent lights vs grow lights.

VIVOSUN describes the light as balanced blue and violet for vegetative growth, and says its average recommended usage life is well over 20,000 hours.

The main tradeoff is simple: bulbs alone do not provide the housing, mounting method or wiring. If you want a complete 4 foot grow light fixture, compare the LED strips below; if you want other replacement lamps, see best 4 foot grow light bulbs.

Barrina 4FT T8 Plant Grow Light: Best for linking a long shelf row

9.6/10Our score

• 6-pack of 4 ft LED strips
• Full spectrum
• Links up to 6 strips
• 3100 lumens

This six-light set can cover a long shelf or bench, with strips that link in series. Barrina says the lights work for shelves, seedling cultivation and greenhouses.

See it on Amazon

Pros

• Six lights in a pack
• Link up to 6 strips
• Includes tape, clips and cable ties

Cons

• Pinkish white light
• Check connector compatibility when combining generations

Barrina's T8 set is aimed at a long shelf or bench that needs several bars. It includes six 4 ft LED strips, and Barrina says you can connect up to six in series.

The stated fixture dimensions are 47.1 x 1.3 x 1.38 in, which makes the strip relatively narrow. Included tape, clips and cable ties give you several ways to attach the lights, while the aluminum shell supports heat dissipation.

Barrina describes the output as full spectrum and lists 3100 lumens. The light color is pinkish white, so consider how that will look in a room where you spend time.

This is a strong fit when you need a coordinated set for a wider growing area. Check connector compatibility before joining newer and older Barrina lights, since the brand notes that some combinations need updated male-female cables.

3

APICDOM LED Grow Light 4FT Full Spectrum: Best for one slim fixture

9.5/10Our score

• 46.1 in integrated LED fixture
• 30 watts
• 3600 lumens
• Links up to 4 lights

The slim 46.1 in fixture offers a single-light option for a shelf or under-cabinet setup. It can hang or mount flush, and up to four lights can connect together.

See it on Amazon

Pros

• Slim, lightweight design
• Two mounting options
• Inline on/off switch

Cons

• One light per pack
• Confirm the fixture length fits your shelf

APICDOM offers a single integrated fixture for a shelf that needs one long bar. Its 46.1 in slim body uses 30 watts and has a stated output of 3600 lumens.

You can hang it with the included 2 ft cable or mount it flush with screws. The inline switch keeps on and off control at the cord, and up to four units can connect to one power cord.

APICDOM describes the light as full spectrum with a 660 nm red-light enhancement. The 5000K light and one-bar pack make it a focused choice for a smaller shelf section, or a starting point you can expand later.

Choose this if you want one slim LED bar with two mounting options. Measure the shelf and available hanging clearance first, because a nominal four foot fixture still needs room at its ends.

4

Barrina Plant Grow Lights: Best for daylight white shelves

9.4/10Our score

• 6-pack of 4 ft LED strips
• 5000K daylight white
• Links up to 6 strips
• Includes connecting cords and clips

This Barrina set uses 5000K white light and includes cords, clips and cable ties for a multi-strip shelf setup. Its daylight-white color may suit rooms where you prefer a less pink appearance.

See it on Amazon

Pros

• Six lights in a pack
• 5000K white light
• Includes three power cords and connecting cords

Cons

• Check the 48.8 in dimension against shelf space
• Confirm connector compatibility when combining generations

This Barrina set pairs six long strips with 5000K daylight white light. It includes three power cords, connecting cords, clips, tape and cable ties, and the strips can link up to six in series.

The stated dimensions are 48.8 in long, so these lights need a little more shelf length than some other four foot models. Their white color may be a better visual fit than pinkish white if the grow area shares space with a kitchen or living room.

Barrina describes the lights as full spectrum for seeding, growth and bloom. The included hardware supports several mounting approaches, but plan the cable path before placing six bars across a bench.

Choose this set when you want multiple daylight-white bars and have enough room for their full length. If your shelf is shorter, compare the 46.1 in APICDOM or the two-foot options in best Feit Electric LED grow lights at 2 ft.

5

FREELICHT 1Pack 4FT Grow Light for Indoor: Best for one full spectrum bar

9.3/10Our score

• 45.3 in LED fixture
• 60 watts
• Hanging or surface mounting
• Links up to 4 units

This single 45.3 in fixture offers hanging or surface mounting for indoor shelves, kitchens or greenhouses. FREELICHT describes its spectrum as suitable from seeding through growth and bloom.

See it on Amazon

Pros

• Mounting hardware included
• Links up to 4 units
• Aluminum body

Cons

• One light per pack
• Not dimmable

FREELICHT's single bar measures 45.3 in, making it one of the shorter fixtures here. Its 60 watt full spectrum LED has red and blue wavelengths, and the included hardware supports hanging or surface mounting.

The brand describes the spectrum as suitable from seeding through growth and bloom. The bar can link with up to four units, which gives you room to extend coverage without starting with a multi-pack.

This is a practical choice when one fixture fits the shelf and you want the option to add more later. FREELICHT says the metal back helps with heat dissipation, and the light is not dimmable.

Check the 3.3 in width and mounting plan along with length. That extra width may matter on a narrow shelf even when the ends fit.

6

TYAGMAM Grow Light for Indoor Plants: Best for a four-light set

9.2/10Our score

• 4-pack of 4 ft LED lights
• 5000K full spectrum
• 180 watts total
• Links up to 4 lights

Four 46 in lights give you several bars for a bench or wide shelf. Connecting cords and clips support linked or mounted arrangements.

See it on Amazon

Pros

• Four lights in the set
• 5000K full spectrum
• Includes connecting cords and clips

Cons

• Pink light color
• Four-light set needs room for its full layout

TYAGMAM's four-light set provides four 46 in T8 LED bars for a wider shelf or propagation bench. For help sizing the output, see our grow light wattage guide.

The set uses 180 watts total and includes connecting cords, clips and hanging rings.

The brand describes the output as full spectrum at 5000K. For water-based growing setups, compare grow lights for hydroponics.

Reflectors are integrated with the tubes, and the bars can connect in series up to four lights.

The listed color is pink, so check whether that suits the room where the plants will sit. Multiple installation options help you arrange the bars across a shelf, stand or ceiling, depending on the hardware and available clearance.

Choose this set when four separate bars match the width of your growing area. For a simpler layout, a single long fixture may be easier to position and wire.

7

FREELICHT 2Pack 4FT Grow Light for Indoor: Best for two linkable bars

9.1/10Our score

• 2-pack of 4 ft LED fixtures
• 40 watts per light
• Links up to 4 lights
• Hanging or mounting

This two-light set can cover more of a shelf than a single bar, and it supports linking up to four fixtures. FREELICHT includes parts for hanging or mounting.

See it on Amazon

Pros

• Two fixtures in the set
• Linkable up to 4 lights
• Includes mounting hardware

Cons

• Red and white spectrum
• Measure shelf depth and clearance before mounting

This FREELICHT package includes two 45.67 in LED bars, each rated at 40 watts. They link with up to four lights and can be hung or mounted using the included hardware.

FREELICHT describes the output as full spectrum and suitable from seedling to flowering stages. The red and white spectrum may look different from a 5000K daylight-white fixture, so consider the room as well as plant coverage.

A two-pack is a middle ground between one bar and a larger multi-pack. Place the bars across the shelf to spread light over more of its width, then leave access for the included cords and switch.

Choose these if two linkable bars suit your bench layout. For a single longer light with more stated lumens, compare the APICDOM fixture above.

8

Sunco 4 Pack 4FT Full Spectrum LED: Best for four full spectrum fixtures

8.6/10Our score

• 4-pack of 4 ft LED fixtures
• 4000 lumens
• Links up to 4 fixtures
• Mounting hardware included

Sunco's four-light set suits a larger growing area that needs several long fixtures. The lights can mount or hang, with up to four fixtures linked together.

See it on Amazon

Pros

• Four lights in the set
• 4000 lumens
• Mounting hardware included

Cons

• Pink light color
• Wider fixture dimensions need shelf clearance

Sunco's four-pack gives you four 48 in full spectrum LED fixtures for a larger setup. Each fixture is 7.59 in wide, so check shelf depth and spacing before deciding how to arrange them.

Sunco lists 4000 lumens and includes mounting hardware. The fixtures can mount directly or hang from the ceiling, and up to four can link in a greenhouse or indoor growing area.

The wider body is the main planning point. These are less like narrow strips and more like broad fixtures, which can suit a bench with enough depth but may crowd a shallow plant shelf.

Choose this pack when you want four fixtures and have space for their width. For narrow shelf rails, a slim strip design may be easier to fit.

Sunco 2 Pack 4FT LED Grow Light: Best for a smaller two-light layout

8.1/10Our score

• 2-pack of 4 ft LED fixtures
• 2000 lumens
• Links up to 4 fixtures
• Mounting hardware included

This two-fixture Sunco set is an option for a smaller shelf or bench layout. It supports direct mounting or suspension and can link with up to four fixtures.

See it on Amazon

Pros

• Two fixtures in the set
• Mounting hardware included
• Linkable up to 4 fixtures

Cons

• Red and blue spectrum
• Check the exact fixture dimensions before planning the layout

This Sunco two-pack offers two 4 ft full spectrum fixtures for a smaller layout. The lights have a red and blue spectrum, include mounting hardware and can connect with up to four fixtures.

Sunco describes the fixtures as suitable across seeding, vegetative and flowering stages. The stated output is 2000 lumens, and the setup supports direct mounting or suspension from a ceiling.

The product data gives a 5.1 x 4 x 1.85 in dimension, which is not a typical long-bar measurement. Confirm the physical fixture size and arrangement with Sunco before planning around a 48 in shelf.

Consider this set when the two-light count and linkable design fit your project. For a daylight-white shelf system, the Barrina set above is a closer match.

How do you choose a four foot grow light fixture?

Start with the fixture's actual length, then check the shelf depth, plant coverage, mounting space and outlet location. A four foot label does not guarantee an exact 48 in body.

A propagation bench may need several bars across its width rather than one centered fixture. Check pack size and whether the lights connect together, then plan how cords will reach power without crossing the growing area.

Is a four foot LED grow light or a bulb the better fit?

Choose a complete LED fixture if you need the bar, wiring and mounting parts together. Choose replacement fluorescent bulbs if you already own a compatible fixture and can match the bulb base and length.

The VIVOSUN bulbs here are 46 in T5 lamps with a G5 base. They won't replace an integrated LED strip or fit every fluorescent housing.

What does full spectrum mean for indoor plants?

Full spectrum describes light across a broader range of wavelengths, but the term alone doesn't tell you how much light reaches your plants. Compare the maker's stated fixture output and follow the plant's light needs and distance guidance.

Our guide to Best Full Spectrum Grow Light covers more fixture choices, while What Is a Full Spectrum Grow Light? explains the term.

Which four foot grow light should you choose?

Pick the Barrina 4FT T8 set when you need several linkable strips for a wide shelf, APICDOM when you want one slim fixture, and VIVOSUN when you need replacement T5 bulbs. Match the fixture's real length and width to your bench before deciding how many bars to buy.

Frequently asked questions

How long is a four foot grow light?

A four foot grow light is usually close to 48 in, but its actual length varies by model. The fixtures here range from 45.3 to 48.8 in, so measure the shelf or bench before you buy.

Leave room for the power cord and any mounting hardware.

Are four foot LED grow lights better than fluorescent lights?

LED and fluorescent fixtures differ in light source, power use and replacement needs. LEDs are integrated in many fixtures, while fluorescent systems may use replaceable bulbs.

Compare the fixture type and maintenance needs for your setup in What Is the Difference Between LED and Fluorescent Grow Lights?.

Can fluorescent lights grow indoor plants?

Yes. Fluorescent lights can support indoor plant growth when the fixture, distance and light schedule suit the plants.

A four foot T5 bulb is useful only with a compatible fixture.

Read Can You Grow Indoor Plants Under Fluorescent Lights? for setup considerations.

Should you choose a four foot fixture or replacement bulbs?

Choose a complete fixture if you need the housing, cord and mounting parts as well as the light source. Choose replacement bulbs when you already have a compatible fixture and need lamps of the correct length and base.

See our guide to best 4 foot grow light bulbs for bulb options.

What should you check before installing a long grow light?

Measure the shelf, confirm mounting clearance and decide how many bars you need to cover the plant area. Check whether the lights link together and whether the included cords reach your outlet.

For shorter shelves, compare best Feit Electric LED grow lights at 2 ft with these longer fixtures.
