LED grow bulb

KOBI PLANTY B E27 9W LED Grow Bulb, 1200K, Black

Dual 430–460 nm and 580–730 nm spectrum that carries plants from growth through flowering and fruiting.

The KOBI PLANTY B E27 is a specialised LED grow bulb for indoor cultivation where daylight runs short. It screws into any standard E27 socket, from a desk lamp or clip light to a grow shelf, and its 38° beam keeps the light on the pots instead of the whole room.

Two wavelength ranges for every growth stage

The 430–460 nm range drives vegetative growth, while 580–730 nm supports flowering and fruit set. Together they stand in for missing sunlight when you raise herbs, vegetables and seedlings indoors.

Focused 38° beam for shelves and mini greenhouses

With 300 lm from just 9 W, the bulb keeps running costs low even when it lights your plants daily through autumn and winter. It suits windowsills, plant stands, grow tents and seedling shelves alike.

25,000 h lifespan and 50,000 switching cycles

Daily on/off cycling from a timer does not shorten the bulb's service life. The -10 °C to +40 °C operating range also allows use in an unheated greenhouse or conservatory.

Made for plants, not for room lighting

The 1200 K colour temperature and Ra ≥ 20 colour rendering are tuned for photosynthesis, which is why the manufacturer does not recommend the bulb for general room lighting. The black plastic housing needs no maintenance.
