The light uses a high level LED chip which is energy-saving and more steady. It has lower light decay, which is lower than 2% glowing every 3000 hours. This kind of LED chip dissipates less heat when glows so that the light can be more durable and energy-saving. In addition, the light color is clearer with a higher color rendering index. A good LED chip is very important. More led doesn't necessarily mean more bright. Choose good led.
