Malfunction or damage resulting from vibration, dropping, or other shock or from inappropriate handling Malfunction or damage resulting from incorrect usage or from improper repair, alteration, or disassembly Malfunction or damage resulting from connecting the product to lighting equipment or a power supply made by another company However, even if a claim is made within the warranty period, you will be charged in the following situations: When used in accordance with the instruction manual under usage conditions specified by Leimac, in the event of a product malfunction within the warranty period, Leimac shall repair the product free of charge or provide a replacement product. It may be said that it is the “past life”when it is 20% down from the initial brightness for those who think present brightness is just enough.įor the customers satisfied with 50% luminance of the light capacity in the initial stage, luminance decreased to 50% of the initial value may be considered to be still usable since required luminance can be maintained by increasing power supply as the luminance decreases.Īccordingly, we cannot uniformly define the life of light. The LED life time of required brightness is different depends on the customers from what percent of brightness is required compared to the initial. This definition of LED life also applies to LED lights with LED elements mounted. ![]() ![]() Accordingly, the life of an LED is defined as the time it takes for LED luminance to decrease to 50% of initial luminance at an ambient temperature of 25☌ not the time it takes until the LED no longer lights up. However, over time the LED’s light transmission rate will decrease and its light flux will degrade due to the degradation of the LED chip and the resin that seals the chip. Due to its very nature, an LED will not completely cease lighting up, unlike an incandescent lamp which will no longer light up once the filament wears out. ![]()
