Nanjing LED SMD Light Supplier, Processing, Manufacturing, Custom Made [Nanjing Weishibo Electronics Co., Ltd.] 1. Brightness - LED brightness varies, as does price. LEDs for lighting should meet Class 1 laser standards. 2. Electrical Resistance - LEDs with high electrical resistance have longer lifespans and are thus more expensive. Typically, LEDs with electrical resistance over 700V are suitable for LED lighting. 3. Wavelength - LEDs with consistent wavelengths have uniform colors; uniform color requirements lead to higher prices. Manufacturers without spectrophotometers find it challenging to produce pure-color products. 4. Leakage Current - LEDs are unidirectional conductors. Reverse current is called leakage. LEDs with high leakage current have shorter lifespans and lower prices. 5. Beam Angle - Different LEDs have different beam angles. Special beam angles are more expensive, such as full-diffused angles. 6. Lifespan - The key to different quality LEDs is their lifespan, which is determined by lumen depreciation. Lower lumen depreciation results in longer lifespan and higher prices. 7. Chip - The light-emitting body of LEDs is a chip, with different types of chips. Nanjing Weishibo Electronics Co., Ltd., located in the beautiful ancient city of Nanjing, primarily focuses on the development of industrial control and 3C backlight solutions. The company integrates the LED industry chain and applications, actively engages in backlight, LED components, and other application products, forming a vertical backlight industry chain. It adheres to international standards for product and service quality.
