The Daystar has evolved from our high performance GLX commercial greenhouse reflector. The greenhouse challenge is to offer not only the most uniform lighting pattern for crops, but also the most efficient lighting systems possible so that the crop can get to market at the lowest possible production cost. There is no room for poor performance anywhere. The Daystar uses the highest purity and efficiency European aluminum and was designed by the finest reflector engineers in the country.Super efficient with both 1000W sodium and halideBuilt-in cord setIntegrated hangersLow profile design for lower clearance areasPatented cool running double wall designCompact and lightweight; easy to hangDesigned exclusively for Hydrofarm by America's foremost lighting design engineers.
