How we chose SANSI grow light bulbs
We compared SANSI bulb shapes, wattages, spectrum details, beam angles and controls to match bulbs with different indoor plant arrangements. Our score weighs specs, features and buyer feedback against what you're shopping for.
The top-ranked 15W A19 pairs a compact shape with a 27 umol/s PPF, making it a sensible fit for one plant and one socket. Higher wattage can suit a denser or larger arrangement, but don't assume a single bulb will cover every plant evenly.
SANSI grow light bulb sizes and outputs compared
The A19 and PAR20 are the smallest shapes in this group, A21 bulbs need more fixture clearance, and BR30 bulbs have a broader body with different beam options. Compare the bulb's actual wattage and stated light output with the size and spacing of your plant area.

The best SANSI grow light bulbs for different plant setups
These SANSI bulbs range from a compact 15W A19 to a remote-controlled 40W BR30. Pick by the number of fixtures and plants you need to light, then confirm the shape fits your lamp.
SANSI Grow Lights for Indoor Plants: Best for a single plant
- 15W actual wattage
- A19 shape with E26 base
- 4000K full spectrum
- 27 umol/s PPF
The A19 shape fits a compact single-bulb arrangement, and the 15W draw is the lowest among these individual bulbs. SANSI gives a 27 umol/s PPF figure.
Pros
- Compact A19 form
- 4000K daylight
- ETL listed
Cons
- Lower PPF than the larger bulbs
- No dimming feature specified
The 15W A19 is the easiest fit when you want a grow bulb in a regular E26 socket without a large bulb body. It uses 4000K daylight and has a 60-degree beam, so it's better suited to a focused placement than a wide shelf.
SANSI gives this bulb a PPF of 27 umol/s and PPFD of 152.83 umol/s/m² at 1 ft. Those figures help compare it with the other bulbs here, but the light reaching leaves changes with distance and placement.
This model is ETL listed and has a stated 25,000-hour operating life. Its 3.9 in height is relatively compact for a grow bulb, which can help when a nearby shelf limits clearance.
Choose it for one plant or a small group close together. For an array of plants across a longer shelf, use more than one socket or compare the grow light bulb types that can spread light across an area.
SANSI Grow Light Bulbs for Indoor Plants: Best for a focused plant corner
- 24W actual wattage
- BR30 shape with E26 base
- 4000K daylight
- 36.2 umol/s PPF
The larger BR30 form and 24W draw suit a plant corner with one socket. Its 60-degree beam is narrower than the 120-degree BR30 option.
Pros
- Higher PPF than the 15W A19
- 4000K daylight
- ETL listed
Cons
- Larger BR30 shape needs fixture clearance
- No remote control specified
The 24W BR30 offers more output than the 15W A19 while retaining a 60-degree beam. Its larger 5.16 x 6.65 in body needs more room in the fixture and around nearby leaves.
SANSI gives this bulb a PPF of 36.2 umol/s and a PPFD of 177.06 umol/s/m² at 1 ft. It uses 4000K daylight and has an E26 base, so it fits compatible medium sockets.
The BR30 shape can suit a focused plant corner where a single bulb needs to serve more than one nearby pot. Keep the beam centered over the plants and check how evenly it reaches the outer leaves.
Choose this model if you want a step up from the smaller A19 and have room for the wider bulb. For a broad arrangement, compare its 60-degree beam with the 120-degree option below.
SANSI LED Grow Light Bulbs 6-Pack: Best for several small fixtures
- Six 10W bulbs
- PAR20 shape with E26 base
- 4000K daylight
- 16.8 umol/s PPF per bulb
Six compact PAR20 bulbs make it easier to spread light across separate sockets. Each uses 10W and has a stated PPF of 16.8 umol/s.
Pros
- Six bulbs in one pack
- Compact PAR20 form
- 4000K daylight
Cons
- Lower output per bulb than larger models
- Multiple sockets are needed to use the full pack
The 6-pack of 10W PAR20 bulbs makes sense when you have several separate E26 fixtures. Each bulb is compact at 3.07 x 3.86 in and has a 60-degree beam, so you can place bulbs over individual pots rather than relying on one central light.
SANSI gives each bulb a PPF of 16.8 umol/s and PPFD of 97.91 umol/s/m² at 1 ft. Each uses 4000K daylight and has a stated 25,000-hour operating life.
A multi-bulb setup can spread light more evenly if the fixtures are positioned over the plants. It also means more sockets and cords to arrange, so plan where each bulb will sit before buying a pack.
Choose the 6-pack for a row of small plants with several compatible fixtures. If you have only one socket, a single higher-output bulb may be easier to position.
SANSI 32W Grow Light Bulbs for Indoor: Best for higher output in one socket
- 32W actual wattage
- A21 shape with E26 base
- 4000K daylight
- 423 umol/s/m² PPFD at 1 ft
This A21 bulb has a higher wattage and stated PPFD than the smaller options. Its wider body calls for a fixture with enough room around the socket.
Pros
- Highest stated PPFD among the listed standard bulbs
- 4000K daylight
- ETL listed
Cons
- Larger A21 form
- No dimming feature specified
The 32W A21 is the strongest choice here when you want a higher-output bulb in one socket. Its stated PPFD is 423 umol/s/m² at 1 ft, and the 60-degree beam focuses the light rather than spreading it across a wide area.
This bulb is 5.63 in tall and 3.27 in wide, so check the lamp shade and nearby shelf before fitting it. It uses an E26 base and gives 4000K daylight.
SANSI states a 25,000-hour operating life and ETL listing for this model. Use the height and fixture clearance as practical checks, especially if plants sit under a shelf.
Choose it for a compact, high-light placement where plants can sit below the bulb. For a longer shelf, use multiple points of light or a wider beam instead of expecting one focused bulb to cover the full span.
SANSI 24W Grow Light Bulbs for Indoor: Best for a mid-size plant group
- 24W actual wattage
- A21 shape with E26 base
- 4000K daylight
- 227 umol/s/m² PPFD at 1 ft
The 24W A21 offers a middle option between the compact bulbs and the 32W model. Check fixture clearance for its 5.47 in height.
Pros
- A21 shape for a larger bulb fixture
- 4000K daylight
- ETL listed
Cons
- Bigger than an A19 or PAR20 bulb
- No dimming feature specified
The 24W A21 sits between the 15W A19 and 32W A21 in actual wattage. It has a stated PPFD of 227 umol/s/m² at 1 ft, which makes it a middle option for a small cluster of plants.
Its 5.47 in height is close to the 32W bulb, so the lower wattage doesn't mean a smaller body. It also has an E26 base, a 60-degree beam and a 4000K daylight color.
This shape works when you want an A21 bulb but do not need the highest wattage in the group. Check the space between the socket and the nearest shelf, leaf or lampshade before choosing it.
Choose the 24W A21 for a modest plant grouping with room for a larger bulb. If you want broader coverage from one socket, consider a BR30 with a wider beam.
SANSI 200W Equiv. Full Spectrum LED Grow: Best for broad coverage
- 24W actual wattage
- BR30 shape with E26 base
- 120-degree beam
- 126 umol/s/m² PPFD at 1 ft
The 120-degree beam is suited to spreading light across a broader group than a narrower beam. It is a BR30 bulb with a 24W draw.
Pros
- Wide 120-degree beam
- 4000K daylight
- E26 base
Cons
- Lower stated PPFD than the 32W model
- No dimming feature specified
The 24W BR30 with a 120-degree beam is the clearest fit for spreading light across a wider arrangement. Its broad beam angle can cover more area than the 60-degree BR30, though distance and plant spacing still affect the light each leaf receives.
SANSI gives this bulb a PPFD of 126 umol/s/m² at 1 ft. It uses 4000K daylight and an E26 medium base, and the bulb's stated operating life is 50,000 hours.
The BR30 body is 5.16 in wide and 6.65 in high. Confirm that your fixture can accommodate it, then center it over the area you want to illuminate.
Choose this model for a wider group of nearby pots where broad spread matters more than the highest stated PPFD. For very spread-out plants, a light on a frame may let you position the source more evenly.
SANSI Dimmable Grow Light Bulb Full Spectrum: Best for adjustable brightness
- 40W actual wattage
- BR30 shape with E26 base
- Four brightness levels
- Remote timer for 4, 8 or 12 hours
Remote controls let you select among four brightness levels and 4, 8 or 12-hour timing options. This is the highest-wattage bulb in the group.
Pros
- Four brightness levels
- Remote timer
- 3800 lumens stated
Cons
- Remote adds another item to keep track of
- No beam coverage beyond 60 degrees specified
The 40W BR30 adds controls that the other bulbs here don't specify: a remote, four brightness levels, and timer settings for 4, 8 or 12 hours. This can help if you want to adjust light output or schedule without reaching the fixture.
SANSI lists a maximum output of 3800 lumens and a PPFD of 345 umol/s/m² at 1 ft. The bulb uses 4000K light, an E26 base and a 60-degree beam.
Dimming gives you a way to adjust brightness, but the bulb still needs sensible placement and a schedule suited to your plants. Keep the remote in a place where you can find it when you want to change a setting.
Choose it when remote control and timing are useful in your setup. If you don't need those controls, one of the simpler fixed-output bulbs may be easier to use.
SANSI 300W Equiv. Full Spectrum LED Grow: Best for added red spectrum
- 30W actual wattage
- B17 shape with E26 base
- 5000K daylight
- Includes 660nm red supplementary light
This bulb combines a 5000K daylight color with additional 660nm red supplementary light. Its B17 form is shorter than the A21 bulbs.
Pros
- Includes 660nm red supplementary light
- 5000K daylight
- E26 base
Cons
- Color differs from the 4000K models
- PPFD figures differ between the provided descriptions
The 30W bulb with 660nm supplementary red light stands apart from the 4000K models. It uses a 5000K daylight color and covers a stated 380nm to 780nm range, with extra red light described for flowering and fruiting support.
Its B17 shape is 4.48 in tall and uses an E26 base. SANSI gives a PPFD figure in the bullet details of 336 umol/s/m² at 1 ft, while another description gives a different figure; compare the bulb by its shape and spectrum as well as its output.
This model may suit growers who want the added red component in a single bulb. Its 5000K appearance differs from the 4000K daylight bulbs, so consider how the light will look in the room.
Choose it for the added 660nm red light and a compact B17 form. If the color and spectrum are not priorities, the 4000K bulbs offer more direct comparisons across the other options.
Which SANSI bulb fits your plant arrangement?
The right bulb depends on how many plants share the light and whether you can place several sockets over them. A single plant can use the A19, while a shelf of separate pots may be easier to cover with several PAR20 bulbs or a wide-beam BR30.
For one socket and a compact footprint, start with the 15W A19. If you want more output in one focused spot, compare the 32W A21 and confirm that your fixture has enough height.
For a broader group of plants, the 120-degree BR30 gives the widest stated spread in this set. A light with a stand can make height and placement easier to change as plants grow.
What should you check before choosing a SANSI grow light bulb?
Check the bulb shape, base, beam angle and actual wattage before comparing equivalent wattage labels. Every bulb here uses an E26 base, but A19, A21, PAR20, BR30 and B17 shapes take up different amounts of space.
Also consider whether you'll benefit from remote controls or a multi-bulb pack. The dimmable 40W model has timer settings, while the 6-pack works only if you have enough compatible fixtures to use its bulbs.
Light distance matters, too. A PPFD figure at 1 ft is a comparison point, not a promise of the same light level at a different height or across every leaf.
How does a SANSI bulb compare with other grow light options?
SANSI bulbs offer E26 screw-in formats for existing fixtures, while some grow lights come as panels, bars or stand-mounted lamps. A replacement bulb can be simple to add to a room, but its coverage depends on the fixture position and beam.
For more choices, compare our best small grow light bulbs and the broader Best Grow Light On A Stand guide. Those formats can work better when plants occupy a shelf or table rather than one spot under a socket.
Which SANSI grow light bulb should you choose?
Choose the 15W A19 for one plant and a compact fixture, the 6-pack when you have several small sockets, and the 120-degree BR30 for a broader plant cluster. Pick the 40W dimmable model if remote brightness and timer controls matter, or the 30W bulb if you want added 660nm red light.
Compare the bulb's shape with your fixture and the beam with your plant spacing before deciding. That check will help you choose a SANSI bulb that fits both the socket and the arrangement.

Frequently asked questions
Which SANSI grow light bulb is best for one plant?
The 15W A19 is a compact choice for one plant in a single-bulb fixture. It has an E26 base, 4000K light and a stated PPF of 27 umol/s.
Match the bulb's distance and daily run time to the plant's light needs, then watch for signs that the leaves are getting too much or too little light.
What is the difference between SANSI A19, A21 and BR30 bulbs?
A19 is the most compact shape here, A21 is larger, and BR30 has a broad reflector-style body. The 15W SANSI model is A19, the 24W and 32W models are A21, and several 24W models are BR30.
Check fixture space and beam angle as well as wattage before choosing.
Are SANSI grow light bulbs full spectrum?
The listed 4000K SANSI bulbs are described as full spectrum, covering the visible range from 400nm to 780nm. The 30W model also adds 660nm red supplementary light and uses a 5000K daylight color.
A daylight appearance can make plant care easier to view, but it doesn't tell you the light level at the leaves.
Can one SANSI bulb light several plants?
It can, depending on the bulb's beam, height and how closely the plants sit together. The 120-degree BR30 is designed for a wider spread, while the 60-degree models focus light over a narrower area.
For several plants on a shelf, compare best small grow light bulbs and consider whether a stand gives more even placement.
How do I choose between a bulb and a grow light stand?
A bulb works with a compatible E26 socket you already have, while a stand gives you a dedicated frame for positioning light over plants. Choose based on fixture access, shelf layout and how much control you need over distance.
See our Best Grow Light On A Stand and Best Grow Light Stand guides for stand-based options.
