This Sunmaster 400W dual spectrum HPS grow lamp has been designed to cater for all stages of the plant growth cycle. Unlike a regular HPS lamp that puts out red spectrum light for the flowering / fruiting stage of development, the 400W dual spectrum bulb also puts out enough blue spectrum light to accommodate for both the vegetative and flowering / fruiting stages.

Dual spectrum lamps have grown in popularity in recent times as more and more positive feedback is emerging on their effectiveness at covering all stages of plant growth. Dual spectrum technology not only reduces the cost of buying a separate bulb for the vegetative and flowering / fruiting stages, but with comparable results to using specific metal halide and HPS lamps for each stage, they are an economic choice for most indoor gardeners.

Sunmaster dual spectrum lamps are specifically tailored for the horticultural market and this Sunmaster 400W dual spectrum lamp features:

  • Output of 55,000 lumens
  • Great photosyntentically active radiation (PAR) range
  • Suitable for veg and flower stages
