|---|---|---|---|
| Grow Light Bulbs, Briignite 11W A19 | Briignite | Full spectrum with 1000LM brightness | E26 |
| Briignite LED Grow Light Bulbs 3Pack | Briignite | Full spectrum, energy efficient | E26 |
| SANSI 36W Full Spectrum | SANSI | High PPFD, optical lens for efficiency | E26 |
| Briignite 6 Pack A19 Bulbs | Briignite | Full spectrum, scalable set | E26 |
| Wiyifada 3 Pack Full Spectrum | Wiyifada | Balanced spectrum for all stages | E26 |
Briignite 11W A19 Grow Light Bulbs — 2 Pack

The Briignite 11W A19 grow light bulbs deliver a full spectrum that appears as 4000K white light to the eye, complemented by red and blue wavelengths for plant growth at all stages. They provide 180-degree light distribution with approximately 1000 lumens while consuming only 11 watts, offering significant energy savings. The bulbs are designed to optimize light transmission and support a higher photosynthetic photon flux (PPF) of about 25 micromoles per second, helping leafy greens, herbs, and fruiting vegetables receive balanced illumination. Suitable for seed starting and indoor planting configurations, these bulbs are compatible with standard E26 sockets.
Briignite LED Grow Light Bulbs — 3Pack

This Briignite 3-pack mirrors the full-spectrum approach with a 4000K white appearance and integrated red/blue spectrum, designed to support all growth stages from seedling to fruiting. Each A19 bulb outputs around 1000 lumens at 11 watts, mimicking natural sunlight while keeping energy use low. The 180-degree distribution helps achieve even coverage in compact grow areas, and the PPF rating indicates efficient light delivery for indoor plant growth.
SANSI Full Spectrum 36W Grow Light Bulb

The SANSI 36W grow light bulb is designed for indoor plant growth with a 4000K daylight appearance and an inferred full spectrum from visible wavelengths 400nm-780nm. Its secondary optical design provides a PPFD around 265.58 μmol/s per square meter at 1 foot, delivering efficient light distribution through a lens-assisted system. The ceramic-on-COB heat sink technology reduces thermal resistance, potentially extending bulb life to about 25,000 hours. This model targets higher-light-demand tasks such as seed starting and leafy greens production, offering robust performance in a single bulb footprint.
Briignite Grow Light Bulbs — 6 Pack

The 6-pack Briignite set provides an extended option for larger grow spaces or multiple fixtures. Each bulb maintains a full-spectrum output designed to mimic natural daylight, with a white 4000K appearance and red/blue spectrum enhancements. As with other Briignite bulbs, the 11W design yields an equivalent light output to a 100W incandescent while consuming far less energy, offering a cost-efficient approach for ongoing indoor gardening, seed starting, and hydroponic systems. The uniform A19 form factor ensures compatibility with standard E26 sockets.
Wiyifada 3 Pack Full Spectrum A19 Grow Lights

The Wiyifada 3-pack offers dimmable A19 grow light bulbs with full-spectrum output suitable for indoor growing, including flowers and greenhouse applications. Each bulb emphasizes energy efficiency with a 9W consumption rated to replace up to 100W, while delivering 150-degree light coverage. The balanced spectrum (400-740nm) supports all growth stages, and the bulbs are designed for long life with heat management features aimed at stable operation even with extended use.
Buying Guide
Key purchase considerations for grow light bulbs include spectrum, brightness, energy efficiency, compatibility, and coverage area. Full-spectrum bulbs that imitate natural sunlight can support all plant stages, but some setups may require higher PPFD or multiple units to achieve even coverage. Consider lumen output versus wattage to estimate energy use, and look for bulbs with a robust heat management system to maximize lifespan. E26 base bulbs offer broad compatibility for many fixtures, while additional features like dimming, optical lenses, and ceramic heat sinks can improve light distribution and reliability. When planning, match the number of bulbs to the size of your growing area and the light requirements of your specific plants. For seed starting and leafy greens, closer placement and moderate PPFD typically suffice; for fruiting plants or denser canopies, multiple bulbs at higher intensity may be necessary. Compare sets (2-pack, 3-pack, 6-pack) to balance upfront cost with ongoing energy savings and lighting consistency.
