Light Distribution Curve

Q:LED what kinds of screw bulbs are there?: Ordinary bulb is the most common, is a metal electrode which is threaded, so it requires that one electrode when installing the socket contact thread to pick the zero line, the middle dot electrode lamp power. Otherwise, an electric shock occurs when an accidental contact with the exposed metal. Because of this symmetrical way, the bulb can be threaded to fit the socket.

There are several tiles, and how much does it cost?.

Q:Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?: The difference of power factor is large, and the resistance capacitance pressure drop is below 0.5 PF. Constant current and constant voltage drive PF over 0.9. The resistance drop pressure is really attractive, after all, the price is there. The average person doesn't understand the look.

Q:Will the power of the LED bulb grow longer and longer? Why?: Voltage problems, as well as unstable factors.Long time no change, should

Q:What is the AC voltage of the LED bulb?: The conventional way to make multiple voltages is the 90V-240V ~50/60HZ 12V

Q:How does the LED bulb go with the power?: voltage range as long as the 36V can be achieved, for example: voltage range 24v-80v is very good,

Q:What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp.
