- 7. Advantages of LEDs in Lighting • Reliability (no spontaneous failure) • Emits less heat • Use less power • Energy Efficient • Quick ON / OFF response • Very Helpful for CCTV Surveillance in Night time • Free of hazardous materials • Long lifetime (approx. 40 times of normal bulb) • Longer service intervals for street lights • No Light pollution • Easy to Dim • Flexibility in colors
- 8. Replacement of HPSV to LED’s • Street Lights (250w HPSV) on main roads can be replaced by Energy Efficient LED Lights (60w) • Street Lights (150w HPSV) on sub roads / streets can be replaced by Energy Efficient LED Lights (40w) • Domestic Lights (60w) on streets can be replaced by Energy Efficient LED Lights (18w)

- 16. Conclusions ROI for replacement of 250W HPSV Lamps with 60 Watt LED : 1.5 ( For Exact Replacement ) – 2.0 Years Each 250 Watt HPSV replaced with 60 Watt LED will reduce at least 7.5 Tones of CO2 emission throughout its life time. Inclusion of Solar Panels and Battery will further increase the Savings and can reduce more CO2 emissions. Where as ROI will be little longer ( 4 – 5 years typically). But for remote and unmanned operations ROI for Solar is around 1 year maximum.
