LED lighting advantages


·Lower energy consumption: lower than incandescent light by80%
·Longer lifetime: Over 30,000 hrs lifetime, (1000 hrs for incandescent,6000 hrs for fluorescent)
·Healthy: NO UV, IR and radiation. ( High pressure sodium lamp contains UV and IR)
·Green product : No toxic substances such as Mercury and Xeon and no Elctromagnetic Interfernce (EMI)
·Vision protection : DC drive , no flicker.
·High luminous efficiency : 60% of electric to visible light conversion ratio for LED lighting.(85% for heat,
                                          only 5% for visible light for incandescent lamp.)
