A 10.5-watt A19 LED agriculture bulb for indoor plant growing, delivering 5000K natural light and 1600 lumens in a dimmable, energy-efficient package.
Satco's S11459 agriculture bulb is designed to support indoor gardening by providing the full-spectrum natural light plants need for healthy growth. With a 140-degree beam spread and 5000K color temperature, it mimics daylight to promote photosynthesis in seedlings, herbs, and houseplants. The dimmable feature lets you adjust light intensity, and the 25,000-hour rated life means years of reliable use.
Best for
- Indoor seed starting and seedling trays, mounted in a standard A19 socket with a clamp light or pendant fixture
- Supplemental lighting for houseplants in low-light rooms, placed 6-12 inches above foliage
- Hydroponic or aquaponic grow setups where a compact, dimmable bulb is needed for small to medium plant areas
- Greenhouse shelving units, providing consistent daylight-spectrum light for multiple plants
- Workshop or garage plant propagation stations, where wet-rated safety is required
Not ideal for
- Large grow operations requiring high-intensity discharge (HID) or full-spectrum LED panels – this bulb covers a small area
- Flowering or fruiting stages of light-hungry plants like tomatoes or peppers, which may need higher PPFD
- Spaces where a warm, cozy light is desired – 5000K is cool daylight, not warm white
How bright is it?
1600 lumens – equivalent to a 100W incandescent bulb. This is bright enough for a single plant or a small cluster of seedlings within a 2-foot diameter. For larger areas, multiple bulbs are recommended.
Light color and feel
5000K natural daylight – a cool, crisp white that mimics midday sun. This color temperature is ideal for plant growth as it supports vegetative development. The bulb is dimmable, allowing you to reduce intensity for sensitive plants or during early growth stages.
Sizing and fit
Standard A19 shape, 4.61 inches long and 2.36 inches in diameter. Fits any standard medium-base (E26) socket. The compact size works in clamp lights, desk lamps, or pendant fixtures with minimal clearance.
