Correct LED lamps to promote consumer misunderstanding

LED lighting gradually accepted by ordinary consumers, it is worth noting that, for ordinary consumers for this new LED light source in the understanding of the existence of some errors:

One, a few W LED bulb can replace several W incandescent lamp

Because the incandescent lamp is usually only about the number of watts and not speak lumen number, over time will affect the purchasing habits of consumers. The LED technology is different from the incandescent lamp, because the light efficiency of LED is still developing, so the wattage is not representative of the lumen. Some manufacturers offer a label similar to the "40W incandescent lamp replacement" on the packaging to indicate that consumers are buying.

In short, it is not possible to use W to represent the luminous flux of LED bulbs.

Error two, the greater the power of LED, the brighter the brightness

Is generally believed that the LED power is greater, the flow is greater brightness of luminous flux, representing the brightness will be more bright, in fact, this is a wrong understanding, LED lamp lumens output different power (LM) the size of the higher, more energy saving, such as: 7W and 8W LED bulb compared if 7W, the lumen output is up to 8W, then 7W lamp actually saving more energy than 8W.
