Lumatek High PAR Bulbs 400w

Lumateks range of dual spectrum bulbs are some of the best available right now. Being dual spectrum means that they can be used throughout the entire vegetative and flowering stages if desired. The lamps have strengthened seals and a reinforced arc frame to provide a stable lumen output even when being dimmed or boosted. They have also been tuned to especially match the higher operating frequencies of digital ballasts to produce a higher level of PAR (Photosynthetic Active Radiation) than you would get in other bulbs of equivalent wattages. By upping the amount of PAR light, means your yields and rate of growth will be improved.
