Sharif International are the exclusive distributors of Shanghai Hongyuan Lighting & Electric Equipment Company Ltd., in Pakistan and a complete range of lamps and fixtures are available ex-stock. LVD lamps offer the latest cutting edge illumination technology and by virtue of their energy efficiency offer a significant advantage over HPS/LPS, CFL and Fluorescent Tube Lights. The ROI of LVD Lamps is less than one year in most cases depending on wattage and daily use.

A general comparison of these eco friendly and energy saving lamps with older technologies is being given underneath for quick reference.
