LED replacements utilize the existing HID MH ballast, so the retrofit is simply a matter of removing the HID bulbs and replacing them with LED in the same socket.
LED Offers Long Life Span, Lower Energy Costs, and Retrofit Kits HID Directly.
In addition, a key factor in determining if the added LED bulb life makes a retrofit cost effective is the cost of labor to replace the lamps after the initial installation. HID bulb replacement will require twice the labor compared to LED.
LED technology has potential benefits than long life and lower energy use. It also overcomes specific drawbacks of HID. And after DLC publish 3.1 version screw base at Nov.2015,there is high speed improve trend from HID to LED replacement in North American.
Finally, depending on the type of metal halide bulbs being replaced with LED, the quality of the illumination — better color rendering — can be achieved.In future 5years,HID retrofit is first choice for LED market.
