ABI 18W Full Spectrum LED Grow Light Bulb PAR38 - Blue, Red, Deep Red, Cold White

The ABI 18W full spectrum bulb is our most economical general-purpose grow bulb. By using mostly discrete wavelength chips, this bulb achieves higher operating efficiency than our phosphor-based broad-spectrum bulbs. The red and blue chips are used by chlorophyll, and the added 10000K white chips fill in the rest of the spectrum for use by accessory pigments such as carotenoids, cryptochromes, phototropins, and phytochromes. These often-ignored photoreceptors perform important functions such as regulating the circadian clock, growth signaling, regulating flowering, regulating leaf shape, and more. The white chips also improve the visibility of the plants.

This passively cooled LED bulb is an excellent choice for growing indoor houseplants, herbs, vegetables, and most flowering and fruiting plants. It has blue, red, and deep red wavelengths combined in the best ratio for most indoor plants. The bulb is designed with a 50,000+ hour service life and comes with a 3-year manufacturer's warranty. It is assembled in the USA and fits a standard household E26 socket, with a 100-240V AC input.

The LED configuration includes 3pcs 450-460nm Blue, 6pcs 620-630nm Red, 6pcs 660nm Deep Red, and 3pcs 10000K Cold White, with a drive current of 300mA and a beam angle of 60-degrees. This full-spectrum general-purpose grow light is an excellent choice for providing the necessary light for indoor plants, ensuring they receive the optimal wavelengths for healthy growth and development.
