Significant progress has been made in lighting. There is a big difference between the different lighting technologies available concerning the amount of energy (watts) necessary to generate the same lighting output (lumens). Progress Solar Solutions strives to utilize the most energy-efficient lighting options available to meet the needs of our clients, including LED (light emitting diode, white light), CFL (compact fluorescent light, white light) and LPS (low pressure sodium, yellow tint) lamp types.
