Why use LED?
The lighting efficiency of high power LED lamps is more than eight times that of what incandescent lamps can offer. That means given a certain amount of light that you need, LED lamps would need less watt power.
The rated life of LED ranges from 35,000 to 50,000 hours while an incandescent lamp only has a rated life of 2,000 hours. That means you just saved yourself from purchasing a significant number of lamp replacements, manpower and time needed for maintenance.
For street lights, LED lighting introduces long term savings as compared to the traditional sodium lighting used by local power providers in the Philippines. Lifespan of LED street lamps are 3 to 5 times that of sodium lamps.
