Q:The difference between the Ledt5 lamp and the temperature 3000k and 2700k
3000k lamp tube luminescence is white point, 2700k lamp tube illuminant red a dot.
Q:Can normal LED fluorescent tubes be used in a vacuum?
If only the LED lamp or fluorescent tube in vacuum, and put the other circuit components in vacuum environment, vacuum sealing problem involves connecting, some trouble, if you use in a vacuum environment, the easiest way is through the optical fiber light import vacuum container, relatively simple and convenient
Q:What are the details of the whole process of the LED lamp?
LED lamp tube application CE certification, notice two aspects 1, sample selection, had better be to isolated power supply, power supply aspects need separate power supply L/N line at one end of the input, and weight requirements, should not exceed 500 g is 1.5 meters. It is difficult to meet the weight requirement by more than 1.5 meters. For other details, look at specific products and specific analysis. There are specific tests, detailed analysis... 2, the detection organization's choice. There are international authorities such as TUV, ITS, etc. Customers have these special requirements. According to customer's requirement. It is best to choose domestic CNAS. , Note: in March 2013, LED lighting was added to EN 62493: test standards for 2010, enforcement.
Q:How do you measure the flux of the LED fluorescent tube
Luxmeter, only test fluorescent lamp within a certain range of brightness, the open bright daylight lamp, the light meter to the lights, see distance of one meter range to see how much brightness, two meters how many brightness range. And the best way to test the flux is by using the integral sphere, the data is the most reliable,

Q:Why do my electric cars charge when they open their homes
It is possible that the high frequency pulse of the charger inside the charger is flowing into the power grid, causing the fluorescent lamp ballast to work and burn down. Electric car charger belongs to the circuit structure of the switching power supply, and the internal vibration circuit is used to produce high frequency signal to drive the transformer. Check to see if the interconnection filter and capacitance component of the inner power source of the charger are damaged. The fluorescent lamp ballast is part of the half-bridge inverter circuit, which is more easily disturbed.
Q:I have LED lights on fluorescent lamp tubes, and I have tested five times a dc
No good. 220v is a valid value. The maximum value is 310v, and it burns instantly.I hope my answer will help you.
Q:Do the fluorescent tubes save electricity for 10 minutes, or do they save electricity in a split second?
Although the data is missing, the electric current of the opening is larger and the power consumption is no more than 10 minutes
