600 Watt HPS Ultra Sun Bulb


Ultra Sun High Pressure Sodium (HPS) lamps have a rating of 2000°K, which works great throughout the entire growing cycle, but is especially good for the fruiting and flowing stages of plants.

Robustly constructed with a ceramic insulation plate, a beefy starter and a stainless steel armature, this lamp delivers 90,000 lumens and can be hung horizontal or vertical in open or closed fixtures and is designed for use with modern, efficient E-ballasts.

Pro-tip: Add a Yieldmaster 2 Reflector and an Xtrasun Dial-a-Watt E-Ballast and you’ll be growing in no time.

High Pressure Sodium lamps have a strong red spectrum, which promotes fruiting and flower and increases production. The Son Agro and Super Agro bulb have 30%, and the Hortilux bulb has 25%, more blue light than a regular High Pressure lamp. This will result in shorter compact growth and help reduce elongation. These bulbs allow you grow different plants at various stages of growth, while only using one lamp. (All lamps have a shipping weight of 5 pounds.)
