Sunmaster 600W light bulb

This metal halide lamp with 600 Watts has become very popular for grow rooms and propagation due to its high efficiency.
The blue/white spectrum stimulates root growth and strengthens the plants.
Attention: works only in connection with a E40 socket and the right ballast. Was designed particularly for HPS ballasts. Don't use e.g. an Industria Reflector since the diameter of the lightbulb is larger than costumary HPS light bulbs. But there's no problem with the reflectors we offer, the space is large enough.
