If one LED is broken, will it affect other LEDs work?

No! Each LEDs has external Zener diode which allows current to flow when there is damage LEDs in string circuit. Zener diode also has the ability to improve LED static breakdown.

Does this light emit much heat?

LEDs are the most efficient lights nowadays. They produce so little heat that you can actually let the plant touch the light (although it is not recommended - as you will reduce the size of your growing area). Any heat produced by the unit is absorbed by the heat sink and dissipated by the fans in the rear of the light.

Why choose 9 Band Spectrum LED grow light? Light Spectrum and Plant Absorption.

Dark-Red 650~660nm, 620-630nm : the best spectrum for plant flowering and fruiting;

Blue 430-440nm, 450-460nm : maximum peak points for vegetative growth and absorption;

Orange 610-615nm : can meet the lower nm rating to make leaf larger and the flowers more brilliant as well as attract insects\" pollination for raising fruiting;

white LEDs : full-spectrum / wide-Kelvin provide fill for all missing spectrums and add Lux.

UV 380 - 400 nm: Process of chlorophyll absorption begins. UV(ultraviolet) have the unique function of sterilization &kill phytopathogenic bacteria.

IR There is little absorption by Chlorophyll here, but Phytochrome uses a nice portion. Flowering and germination is influenced.
