High output 6,400° K lamps simulate natural
 sunlight and are ideal for cuttings or vegetative growth. Some 
horticulturist’s choose 2,700° K for budding and blooming. SunBlaster’s 
T5 HO lamp produces a light of much greater strength than a conventional
 tube and, as a result, the energy input into the area being lit is much
 greater and the light penetration is far superior to anything 
previously available.
