The global market for High Intensity Discharge (HID) Bulbs is forecast to decline to US$1.0 billion by 2024, constrained by the growing threat of substitution by light-emitting diode (LEDs) and high efficiency plasma lights. HID bulbs which have been used for years to light streets and factories, are today being rapidly replaced by LEDs. Rising energy costs and tighter energy-efficiency standards and regulations are playing major roles in accelerating the phase out of HID lighting technology. Few of the benefits of LED driving its popularity as a replacement for HID include higher energy efficiency due to lower quotient of trapped light; high efficiency even at higher operating temperatures; greater effectiveness of LED power drivers over HID ballasts; longer durability with an operating life of over 10 to 12 years. Asia-Pacific represents the largest market worldwide, supported by the presence of price sensitive countries in Southeast Asia where energy efficiency regulations remain lax and consumers prefer cheaper HID to the more expensive LEDs. In these countries proliferation of LED is slow with HID bulbs still continuing to be used in infrastructure facilities such as stadiums, large public areas, movie theatres, roadways, pathways, parking lots, and warehouses, among others.
