LED downlight makers raise luminous efficacy, upgrade designs

Upcoming models use imported diodes and integrate value add-ons such as dimmers and solar panels.


  • Greater luminous efficacy: Makers have raised the luminous efficacy from last year’s 65 lm/W to 75 lm/W. Some units can reach 110 lm/W and last 30,000 to 100,000hr. More China suppliers are adopting Osram, Cree, Edison and Epistar diodes in midrange and upscale designs. These models use up to 100 LEDs rated at 3 to 40W.
  • Broader design options: To diversify selections further, companies are rolling out LED downlights in various structures, including round or square bodies, or vertical or horizontal constructions. Some are equipped with a bracket or sun-shaped louver. Aluminum, steel, glass and plastic are the typical materials for the housing, reflector and cover.
  • Value add-ons: A number of high-end variants employ dimmable ballasts that allow manual or automatic brightness adjustment. For greater energy savings, several makers use monocrystalline solar panels. Such releases, however, account for only 5 percent of China’s output.
  • Wider applications: The majority of products are designed for hotels, stores, shopping malls, museums, art galleries, office buildings and residential spaces. Those developed for outdoor areas are fitted with sealed, weather-resistant enclosures.
