How about the PHILPS floodlight?
Leakage current LED pan light is one-way conductive light, and if there is reverse current, it is called leakage, leakage current of large LED, short life, low price.
The light of the wafer LED floodlight is wafer, and the price varies greatly with different chips. The wafers in Japan and the United States are more expensive. In general, the prices of wafers made in Taiwan and China are lower than those in Japan and the United States (CREE).
The key of different quality life is life, life is decided by the light fades. A small decline, long service life, long service life, high price.
LED with different angles of illumination has different luminous angles. Special light angle, higher price. Such as full diffusion angle, higher prices.
1, LED floodlight brightness (MCD) is different, the price is different. The LED for the LED luminaire shall comply with the laser class I standard. 2, antistatic ability, antistatic ability of LED, long life, and therefore high prices. Usually antistatic 700V than LED can be used for LED lighting. 3, wavelength consistent LED, color consistency, such as the same color requirements, the price is high. It is difficult for manufacturers without LED spectrophotometer to produce pure color products.
