Phason Light Dimmer Box - LDB-2 is a two-channel control designed around its functionality and ability to control AC or DC-powered LED, CFL, or incandescent lights.

Benefits of a properly controlled lighting system: 

• Correct light intensity and duration can have positive effects on the health, fertility, and productivity of dairy cattle.
• In poultry, light can be a tool to optimize growth, age of sexual maturity, egg weight, and egg production. 
• In greenhouses, the quality of light has a positive effect on photosynthesis, reproduction, climate response and plant shape.
