Product Review

Optimal spectrum, high efficiency, quality components, and sturdy construction make the ABI broad spectrum grow light the best choice for indoor growing needs.  The ABI broad spectrum grow light is suitable for all types of indoor plants and can be used for both vegetative growth and flowering.  This bulb uses 15x3W chips running at reduced current to improve the efficiency and longevity.  Total power consumption is only 12W.  Typical LED grow lights provide a few narrow wavelength bands that target the absorption spectra of chlorophyll whereas this broad spectrum grow light has a spectral power distribution that is tuned for chlorophyll while also providing suitable wavelengths for 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.  Rather than combining LED chips of various wavelengths, the ABI broad spectrum grow light uses blue chips coated with orange and red phosphors, similar to the way in which white LEDs use blue chips coated with yellow phosphors.  The result is a grow light that is optimized for photosynthesis and covers the entire visible spectrum.  This bulb is assembled in the USA and is backed by a 3-year manufacturer's warranty.
