A standard A19-shaped LED bulb tuned for indoor plants, sold singly. It gives a mostly white full-spectrum light instead of the pink-purple glow of older grow bulbs, so plants look normal and problems are easier to spot. It runs cool, which suits seedlings and houseplants placed close to the bulb. It is a basic screw-in supplement rather than a high-output fixture, so it suits a few small plants, not a full grow tent.

Rated highly by buyers, who mostly use it as a simple supplement for houseplants and seedlings. They like the white light and the low heat. Some find it weaker than expected for larger plants.
This is an LED grow light bulb in the standard A19 shape. It can supplement ambient light for indoor plants, vegetables and herbs, or give new seedlings light before the spring planting season. Because it is LED, it produces very little heat.
The bulb is tuned to give a balanced full-spectrum light that is mostly white, which reduces the pink/purple look of many grow lights. It enhances the most efficient wavelengths for photosynthesis for its total wattage. The white light also makes it easier to see problems or disease on a plant. Each bulb is shatter resistant and designed to last more than 10 years.
For most plants, position the bulb within 1-2 inches of the top of the plant. Seedlings can start using grow light after the first leaf appears. Start with the light about 3 to 5 inches away.
