Multiple constant current output, flexible combination, one LED fault, do not affect other LED work, slightly higher cost. Direct constant current power supply, LED series or parallel operation. The cost is a little lower, but the flexibility is poor, one LED failure, affect the operation of other LED. These two forms coexist for a period of time.

High light efficiency, the highest light efficiency of a company in the laboratory has reached 260Lm /W, and a single high-power LED on the market has exceeded 100Lm /W. Due to the loss of power efficiency and the light pass loss of the lampshade, the actual light efficiency of the made LED energy-saving lamp is at 60Lm /W, while the incandescent lamp is only about 15Lm /W. Good quality CFLs are around 60Lm /W, so on the whole, the light efficiency of LED CFLs is equal to or slightly better than that of CFLs.

The CIE defines the color rendering index of the sun as 100. The color rendering index of various light sources varies. For example, * Sodium color rendering index Ra=23 and fluorescent tube color rendering index Ra=60 -- 90. There are two kinds of color development: Faithful color rendering: To correctly represent the original color of the substance requires the use of high color rendering index (Ra) light source, its value is close to 100, the best color rendering. Effect color rendering: to highlight the specific color, the expression of beautiful life can be used to enhance the color rendering effect.
