Somebody have a lot of confusion!!! Actually they wanted to know What is Full spectrum light?
The term "Full Spectrum" implies that a lamp is designed to produce energy across the full visible spectrum like natural light. This term is often used to describe metal halide arc tube lamps.
Full spectrum light is light that covers the electromagnetic spectrum from infrared to near-ultraviolet, or all wavelengths that are useful to plant or animal life; in particular, sunlight is considered full spectrum, even though the solar spectral distribution reaching Earth changes with time of day, latitude, and atmospheric conditions.
