How To Choose Cost-Effective LED Lamps?
Tip 1: Looking at brightness, its main parameter is luminous flux, the unit is lumens. The higher the brightness, the higher the price. The LEDs used in LED lamps should meet the laser class Ⅰ standard.
Tip 2: Anti-static ability generally requires LEDs with anti-static greater than 700V to be used in LED lamps.
Tip 3: Checking the leakage current. The greater the leakage current, the greater the light attenuation of the led lamp, and the shorter the life span, the lower the cost and the lower the price.
Tip 4: Looking at the wavelength consistency. LEDs with the same wavelength have the same color and pure color. The more consistent the color, the higher the price.
Tip 5: Looking at the light-emitting angle, for special light-emitting angle, the price is higher, this parameter needs to be selected according to different usage requirements.
Tip 6: Asking the brand of chips, the quality of chips from famous Japanese and American manufacturers is higher, and the price is more expensive, while the prices in South Korea, Taiwan and the mainland are lower.
Tip 7: Looking at the chip size. Under normal circumstances, large-size chips are of higher quality than small-size chips, and the price is also higher.
Tip 8: Looking at the lifespan, the comprehensive performance parameters of led lamps, it goes without saying that the longer the life, the higher the price, and the main manifestation is light decay.
Tip 9: Looking at the manufacturing technology, the selection of different auxiliary materials and processing techniques will also have a great impact on product quality and price, such as fire prevention and dust prevention. Many requirements such as rainproof and static electricity will affect the price and cost of led lamps.
