The Sunmaster 400W Tubular HPS Dual Spectrum E40 Grow Lamp 2000K (Part Number/Ref: SL.400W.U46.DSP 10035) is a premium Grow Lamp manufactured by Venture Lighting.
The Sunmaster Dual Spectrum HPS Grow Lamp is designed to provide an optimal photosynthetically active radiation (PAR) range, making it ideal for both vegetative and flowering stages. Unlike traditional HPS lamps that emit primarily red spectrum light for flowering and fruiting, this innovative lamp has been enhanced to include enough blue spectrum light to support vegetative growth as well.
Dual spectrum technology has gained popularity due to its efficiency and convenience, eliminating the need for separate metal halide and HPS bulbs. With the Sunmaster Dual Spectrum, growers can achieve outstanding results throughout the entire plant lifecycle using a single lamp.
