LED bulb is mostly with drive, if there is no self rectifier lamp light, the best is the bulb is directly connected to the E27/E14/B22 lamp, LED lamp or light source has a good energy saving effect, mercury free lead-free, no stroboscopic, energy than traditional fluorescent lamp 80%

Q: What is the 15 Watt lumen of the LED bulb?: Each brand has different bulb qualities, probably around 1W between 60-85LM/W.

Q: How does the LED bulb go with the power?: Generally we use the LED lights, 1W, 2W, 3W, 12W, and so on, the factory has been set in advance, directly connected to the 220 volt power supply can be, and do not need to be so complicated.

Specifications?: Of course, the hotter the better, because for the same material, the hotter it is, the more heat the LED chips use, the less good the quality of the chips. The thermal characteristics of lamps is mainly to measure the junction temperature of LED Shenglai rather than the temperature of heat sink. Aluminum is commonly used in heat dissipation materials.
