High brightness white LEDs are commonly specified to last 50,000 to 60,000 hours at maximum operating conditions. When operated below these maximum conditions, they can last well in excess of 70,000 hours. Well designed fixtures that minimize the lifetime limitations of other system components can take advantage of LED longevity to deliver terrific reliability.

In order to understand the value that this lifetime delivers to lighting users, first one must understand lifetime as defined by LEDs versus traditional light fixtures. LED fixture manufacturers define fixture end of life as a 30 percent reduction in output. This is contrasted with traditional lighting like fluorescent, which typically suffers complete lamp failure. Because fluorescent lamp lifetime is defined as an MTBF, half of the lamps are dead and require replacement by the lifetime rating.

It’s not just about the kilowatts.
Most people are now aware of one key benefit of LED lighting - its efficiency. LED lighting long ago surpassed incandescent efficiency and is now approaching and even surpassing the efficiency of linear fluorescent and metal halide. However, there are many other benefits to LEDs including lasting five to 10 times longer than fluorescents, consuming less energy while on, are fully dimmable, contain no hazardous mercury, are nearly unbreakable, are free of annoying flicker and buzz and are safer, operating on low voltage DC, with no glass or vacuum.
Facilities that are already implementing LED systems are likely not doing so in general illumination applications. LEDs are no longer just for task or accent lighting or color-changing architectural effects, but are now being built into fixtures that are tackling some of the most challenging applications in general lighting, and they’re competing with very-efficient linear fluorescent and very-bright HID. Some LED performance examples include parking garage fixtures from multiple suppliers that deliver more than 6,400 effective lumens while consuming 77 watts, high bay fixtures with 18,000 usable lumens that consume about 190 watts and troffers with 5,000 effective lumens that consume just over 50 watts.

Traditional Street Lights Reformation Program
Adopting new generation of LED lights to substitute traditional street lights is the best way which
makes the semi-conductor LED become an ideal green environmental protection lamp. With the advantage of high-efficiency, energy-saving, long life and green environmental protection, LED Lights accomplished the traditional street lamp reformation as a possibility.
1. The reformation program can save much maintenance expenses, the LED street light’s
life span is 5 times to High Pressure Sodium Lamp’s.
2. Saving much power charges. 70% above than High Pressure Sodium Lamp.
3. The yearly invest return rates is 25% above.
