Domestic consumers have long been accustomed to measure incandescent lamp power (W) for the brightness, so that now see the lighting products to ask how much, this view is actually an error.

      Even the alternative of the same wattage LED lights will be different manufacturers, while the brightness and power consumption is different.

      This brings us to the confusion of consumers in the use of, but also led to controversy among manufacturers for product performance. Even lead to a Look at the cheap price to consumers to buy high-wattage low-brightness products, and an obstacle to the popularization of LED lights.

      To prevent this phenomenon, Tian Fang technology in the lumens as the purchase of led tube lights when the reference standard. Lumen represented by the sum of the visible emission from the light source luminous flux. The lower power consumption, the higher the lumens, the light efficiency of this product, the higher the better the performance of the product.

      Energy-savingled underwater light products have been a selling point if less than the energy saving effect, the product is no advantage, so the Show in the purchase when the power is very wrong. To price lumens parameters make a purchase. To buy a low power, high lumens, and affordable is an affordable LED lighting products.
