1 HILTRON Home

Objective Each Municipal Corporation, Town, Village, Corporate, Institute Campus have provision of Street / Security Lighting arrangements. Most of Street Lights / Security Lights consume average 150W power per pole. Also, replacement of domestic conventional lights by LED luminaires saves electricity up to 80% HILTRON objective is to reduce Street Light / Security Light power consumption 80% by using ENERGY EFFICIENT LED Lights. Home

Advantages of LEDs in Lighting Reliability (no spontaneous failure) Emits less heat Use less power Energy Efficient Quick ON / OFF response Free of hazardous materials Long lifetime (approx. 40 times of normal bulb) Longer service intervals for street lights No Light pollution Flexibility in colors Home

Replacement Street Lights (250w HPSV) on main roads will be replaced by Energy Efficient LED Lights (70w) Street Lights (150w HPSV) on sub roads / streets will be replaced by Energy Efficient LED Lights (35w) Domestic Lights (60w) on streets will be replaced by Energy Efficient LED Lights (4w) Home
