Q:How to connect the power supply when the LED lamp is energized? The search is to get a wire directly from two ends? Do you need to be able to distinguish positive and negative?

The power supply is not positive and negative, and the power supply can only work under the dc environment. Normally bought LED lamp tube has built-in power, can be used directly in the lamp holder, but should be careful to remove the regenerator, short connect ballast. You can also go to LED918 for me.

Q:Do not have the fluorescent lamp of actuator, how to change LED lamp tube?

LED lamp. There are small actuators that only need to be connected, red, and black. Can.. There are other LED lights that need a different starter.

Q:The ambient humidity of the LED daylight lamp is in the range

If you're in a particular high humidity environment, don't use an ordinary led fluorescent lamp, considering the safety of an led lighting device that USES waterproof dust

Q:Can the LED tube be installed as a general lamp holder? It won't burn easily

LED lights need dc power, so the two end of the frame are dc output And the lamp tube needs to communicate electricity, dc is to damage the lamp directly

Q:Who knows about the fluorescent light of 40w, how many w's LED bulbs can replace or exceed its brightness?

My own home is a traditional 40-watt energy-saving fluorescent lamp. Recently modified, replaced with LED fluorescent lamp T8.

Q:Is there a ballast in the LED lamp? Or do you need a ballast?

Fluorescent lamp tube is need to use ballast, whether inductance type or electronic type, need to give lamp tube a high-voltage pulse to light. Leds, unlike leds, need a completely constant current to drive it, so the LED driver is a driver for constant current constant pressure.

Q:What is the conversion between the number of leds and the number of tiles?

In this case, we'll talk about energy efficiency

Q:Help me see the yellow on the left side of the LED fluorescent lamp

The yellow one is the gauge capacitor, the first element on the left is the NTC resistor, the third component is the inductance, and the two components behind the inductance are the electrolytic capacitors,

Q:Fluorescent lamp fire line zero connection

My own LED lights are connected by the zero and the wire, and then the lights will have a very faint afterglow, which will be visible at night. I don't understand. I don't know if I have to reconnect the line.

Q:How to remove fluorescent lamp tube

What material is LED fluorescent lamp fittings, such as shell, block?
