1. Voltage: led lamp beads using low-voltage power supply, the supply voltage between 2-4v, depending on the product varies, so drive it is a higher than the power supply; more secure power, especially for public places;
The same time as the above-
2. Current: working current in 0-15ma, brightness increases with the current and brighten
The same time as the above-
3. Effectiveness: 80% reduction in energy consumption compared to incandescent light.
The same time as the above-
4. Applicability: very small, each unit led small piece is 3-5mm square, it can be prepared into a variety of shapes of the device, and suitable for a variable environment.
The same time as the above-
6. Response time: the response time of its incandescent milliseconds, led light response time for the nanosecond.
The same time as the above-
7. Environmental pollution: no harmful metal mercury.
8. Color: change the current can be discolored, light-emitting diode easily through chemical modification method, adjust the energy band structure and band gap, to achieve red, green and blue orange multi-color light. Such as the small current when the red led, with the increase in current, can turn into orange, yellow, and finally green.http://www.outedsionbulb.com/
