VIVOSUN T5 Grow Light Bulbs 4Ft: Best for replacing 4 ft lamps
- 54W fluorescent bulbs
- 6500K cool white
- 5 bulbs per pack
- 5000 lumens per bulb
These 4 ft replacement lamps suit a compatible T5 HO fixture. Their 6500K light and 5000-lumen output fit seed starting and vegetative growth needs.
Pros
- 5 bulbs in a pack
- 6500K color temperature
- 20,000-hour average recommended usage life
Cons
- Bulbs only, not a fixture
- Requires a compatible 4 ft T5 HO fixture
VIVOSUN’s 4 ft bulbs are the strongest fit when your existing fixture takes 54W T5 HO lamps. Each bulb is listed at 5000 lumens and 6500K, a cool-white color temperature that suits seed starting and vegetative growth.
The pack contains 5 glass tubes. VIVOSUN gives an average recommended usage life of more than 20,000 hours, and describes the bulbs as low-heat options for close growing spaces.
Confirm your fixture’s length and base before replacing lamps. These are bulbs, so you’ll need a compatible housing and ballast.
Choose this pack for a 4 ft fixture that needs several matching replacements. For individual tube comparisons, browse our T5 grow light bulb guide.
VIVOSUN T5 Grow Light Bulbs 2Ft: Best for compact shelves
- 24W fluorescent bulbs
- 6500K cool white
- 5 bulbs per pack
- 2000 lumens per bulb
These shorter replacement lamps suit a compatible 2 ft T5 HO fixture. Their 6500K light and 2000-lumen output are sized for more compact growing areas.
Pros
- 5 bulbs in a pack
- Shorter 22 in format
- 20,000-hour average recommended usage life
Cons
- Bulbs only, not a fixture
- Requires a compatible 2 ft T5 HO fixture
The 2 ft VIVOSUN bulbs suit compact shelves where a full-length lamp would extend beyond the growing area. Each 24W tube produces 2000 lumens at 6500K, and the five-pack gives you replacements for several fixtures or future changes.
VIVOSUN describes these bulbs as suitable for seedlings, tender foliage, indoor plants, vegetables and flowers. Their shorter length makes them easier to plan around small shelves, cabinets or propagation areas.
Check the fixture’s lamp length and base first. The 22 in tubes are not direct replacements for 4 ft lamps.
Pick these when your compatible fixture takes 2 ft, 24W T5 HO bulbs. Choose the 4 ft VIVOSUN pack above for longer fixtures.
Barrina T5 Grow Lights for Indoor Plants: Best for one-foot plant rows
- 4 LED fixtures
- 1 ft length
- 5000K white full spectrum
- Separate on/off switches
Four short fixtures can be linked to cover a shelf or plant row. Each light has its own switch, and installation clips, tape and cable ties are included.
Pros
- Four fixtures in a pack
- Each fixture can be switched separately
- Link up to 16 lights in a series
Cons
- LED lights, not fluorescent tubes
- 1 ft units may need careful placement for broader shelves
Barrina’s four-light set uses short 1 ft LED fixtures, not fluorescent tubes. Each light has a separate on/off switch, and the set includes clips, double-sided tape, cable ties and cords for mounting and linking the lights.
The package draws 20W total and uses 96 LEDs. Barrina describes the lights as 5000K white full spectrum and says up to 16 units can connect in series, which can simplify a longer shelf run.
The short fixtures let you place light across a row in smaller sections. Plan the spacing and mounting points before installation, especially if you need even coverage across a broad shelf.
Choose this set for linked 1 ft sections and separate switching. For fluorescent bulbs, use one of the VIVOSUN or LightWise options instead.
Barrina T5 Grow Lights for Indoor Plants: Best for longer linked runs
- 8 LED fixtures
- 1 ft length
- 5000K white
- Separate on/off switches
This eight-light set provides more short fixtures for linked shelf runs. The manufacturer describes them as full-spectrum lights and includes cords, connectors and mounting pieces.
Pros
- Eight fixtures in a pack
- Link up to 16 lights in a series
- Mounting clips, tape and cable ties included
Cons
- LED lights, not fluorescent tubes
- Short 1 ft fixtures require planning for coverage
This Barrina package contains 8 short LED fixtures, giving you more sections for a multi-shelf or extended setup. Each unit is 1 ft long, and Barrina says the lights can connect in a series of up to 16 units.
The package draws 40W total and includes power cords with switches, connecting cords, clips, tape and cable ties. The lights are specified as 5000K white, with separate switches on each fixture.
This is an LED system despite the T5 naming. It can work for shoppers who want narrow fixtures and modular linking, but it is not a fluorescent tube replacement.
Choose the 8-pack when you need more short, linkable lights than the 4-pack provides. For a wider 4 ft LED option, consider FREELICHT below.
FREELICHT 1Pack 4FT Grow Light for Indoor: Best for a slim LED alternative
- 4 ft LED fixture
- 60W

Pros
- Long 4 ft format
- Hanging or surface mounting options
- Red and blue wavelengths specified
Cons
- LED, not fluorescent
- Not dimmable
FREELICHT offers a slim 4 ft LED fixture for buyers comparing long shelf lights, rather than a fluorescent T5 tube. It uses 60W and has red and blue wavelengths specified, with the maker describing it as suitable across plant development stages.
The package includes hanging or mounting hardware, and up to 4 units can link together. Its 45.3 in length can suit a longer shelf, but check the available clearance and mounting points.
Choose it when you want a long LED fixture with included hardware. If you need fluorescent light, stay with a T5 tube and compatible fixture.
Durolux T5 Grow Light: Best for a complete 2 ft fixture
- Four 2 ft fluorescent lamps included
- 10,000 lumens
- Two switches for lamp groups
- Daisy-chain outlet
This complete fixture includes four 2 ft 6500K lamps, hanging chains and a power cord. Two switches let you turn on the inner or outer pair.
Pros
- Fixture and lamps included
- Two light-output settings
- Can power up to 12 fixtures from one outlet
Cons
- Shorter lamp length limits shelf coverage
- Confirm clearance and mounting space before setup
Durolux’s 2 ft fixture comes with four 6500K fluorescent lamps, hanging hooks and chains, and a power cord. Its 10,000-lumen output and paired switches let you run either the inner two bulbs or outer two bulbs.
The fixture also has an outlet that can power up to 12 fixtures, according to the product details. That may help when building a wider grow area, though you should check your electrical setup and follow the fixture instructions.
At 2 ft, it suits short shelves or propagation areas more naturally than long rows. Measure your growing space and hanging height before choosing it.
Pick this as a complete fluorescent setup for compact shelves. For a longer fixture with four lamps, consider the 4 ft Durolux below.
LightWise LWF54T5HO865 8pack 4 FT 6500K T5: Best for stocking 4 ft replacements
- 8 fluorescent bulbs
- 54W each
- 6500K cool white

- 6500K color temperature
Cons
- Bulbs only, not a fixture

LightWise supplies 8 replacement bulbs for compatible 4 ft T5 HO fixtures. Each 54W tube is 45.12 in long and specified at 5000 lumens and 6500K, making the pack useful when you need several matching lamps.
The company describes its bulbs as suitable for seed starting, cloning and full-term lighting. Check the fixture’s required tube length, wattage and base before replacing your current lamps.

- 5 fluorescent tubes

Pros

Cons

- Verify base and dimensions against your fixture
Arikit’s SunBESTer pack contains 5 fluorescent tubes in a 4 ft, 54W T5 HO format. The stated color temperature is 6500K, or cool daylight white.
Because tube base details can vary across fixtures, compare the lamp base and dimensions with your fixture before ordering. This matters especially if you are switching brands or replacing an older tube.
Choose this pack for five 4 ft replacements when the fixture specifications match. The LightWise pack above provides 8 tubes for a larger replacement batch.
Durolux T5 Ho Grow Light: Best for a bright 4 ft fixture
- Four 4 ft fluorescent lamps included
- 20,000 lumens
- Two switches for lamp groups
- Daisy-chain outlet
This complete 4 ft fixture includes four 6500K lamps, hanging hardware and a power cord. Separate switches control the inner and outer lamp pairs.
Pros
- Four lamps and fixture included
- 20,000-lumen output
- Can power up to 5 fixtures from one outlet
Cons
- Wider footprint needs shelf or hanging space
- Confirm outlet compatibility and clearance
The Durolux 4 ft fixture includes four 6500K fluorescent lamps, mounting chains and hooks, plus a power cord. It is rated at 20,000 lumens, and two switches control the inner pair and outer pair of lamps.
Its listed dimensions are 47.5 x 12.5 x 4 in, so it takes more width than a simple tube or narrow shelf light. The fixture can power up to 5 fixtures from one outlet, according to its product details.
Choose it for a complete, bright 4 ft fluorescent fixture with grouped switching. Make sure your shelf or hanging area can support its footprint and mounting needs.
What should you check before buying a T5 grow light?
Check the fixture type, tube length and lamp base before you order replacement bulbs. A T5 bulb that looks similar may not match your fixture’s electrical or physical requirements.
If you need both housing and lamps, choose a complete fixture with the mounting parts and power cord you need. Durolux’s options include four lamps, chains and hooks, while VIVOSUN, LightWise and Arikit sell replacement bulbs.
Are T5 LED fixtures the same as fluorescent T5 lights?
No, T5 LED fixtures use LEDs rather than fluorescent tubes, even if their product names include T5. Barrina’s 1 ft options and FREELICHT’s 4 ft option in this roundup are LED lights.
LED fixtures can offer linking and compact installation options. If you want the differences explained before choosing a technology, read what separates LED and fluorescent grow lights.
Does T5 mean high output?
No, T5 describes the tube size, while HO means high output. Check the lamp wattage and fixture requirements as well as the T5 label, because compatibility depends on more than tube diameter.
For a side-by-side tube format overview, see the difference between T8 and T5 grow lights.
Which T5 grow light should you choose?
Choose VIVOSUN’s 4 ft bulbs if you have a compatible 54W fixture and need replacement lamps. Pick the 2 ft bulbs for a shorter fixture, or Durolux if you need a complete fluorescent setup with housing and mounting hardware.
For modular shelf lighting, Barrina’s LED sets offer short linkable fixtures, while FREELICHT offers a longer LED format. If you’re still deciding whether fluorescent light fits your plants, read can indoor plants grow under fluorescent lights?.

Frequently asked questions
Are T5 fluorescent grow lights good for seedlings?
Yes, T5 fluorescent lights can suit seedlings when the fixture provides enough coverage and stays at a suitable distance. VIVOSUN describes its 6500K bulbs as gentle on seedlings and tender foliage.
Follow the fixture maker's placement guidance and watch plants for stretching or leaf stress.
What does T5 HO mean on a grow light?
T5 refers to the tube format, while HO means high output. Check the fixture's required lamp length, wattage and base before buying replacement tubes.
A T5 label alone doesn't confirm that a bulb fits every T5 fixture.
Should I buy bulbs or a complete T5 fixture?
Buy bulbs when you already have a compatible fixture and need replacements. Choose a complete fixture when you also need the housing, switches and mounting hardware.
Check whether the package includes lamps because some options are replacement bulbs only.
How do I choose between 2 ft and 4 ft T5 lights?
Choose 2 ft lights for a short shelf or compact plant row, and 4 ft lights for longer growing areas. Measure the usable shelf length and account for fixture edges and mounting space.
For a comparison of tube formats, see our guide to the difference between T8 and T5 grow lights.
