These smart ballast will run either Metal Halide or High Pressure Sodium Bulbs, they are also compatible with 110v-240v as well as generator ready! Just plug it in, the ballast does the rest!

Dimming Function. We offer this option on are larger ballasts to provide the ultimate in flexibility. Allows user to select between 100% 75% or 50% output. Starting seedlings but don't want to move the light up? Simply flip the switch to 50%..Now you are producing less light, less heat and using less energy. No more wasted light/heat/energy burning your light at full capacity when its not needed. Also a great feature to control heat during the summer time.
