High and low meaning
High-level trigger refers to the signal trigger side (IN) and the negative power supply has a positive voltage between the positive and the power supply is usually connected to the trigger side of a trigger, when the trigger side voltage or trigger to reach the trigger Voltage, the relay is pull.
Low-level trigger refers to the voltage between the signal trigger terminal and the negative terminal of the power supply is OV, or the voltage of the trigger terminal is lower than the voltage of the positive terminal of the power supply. When the voltage is low enough to trigger, the relay is pulled in, The negative side of the power supply is connected to the trigger side of a trigger, so that the relay is pull.

Q&A
1. Does the LED flexible filament need a heatsink?
The LED filament does not need a heatsink. The LED uses a current of ≤10mA, and does not require heat dissipation.
2. Can the LED flexible filament be powered with an 18650 battery (DC3.7V)?
No, the LED filament voltage is standard DC3V.
If you use DC3.7V, the voltage is too high and the filament temperature will be very high, which will burn out the lamp beads.
3. Where is the LED flexible filament used?
Generally used in light bulbs, DIY hand-made toys, DIY decoration designs and home projects.
4. Can the flexible LED filament bend 90 degrees?
No. Maximum bending angle of LED filament≥30°
5. Can the flexible LED filament be freely cut to length?
No. If it is cut, it will not light up.
6. Can the length of the LED flexible filament be customized according to customer requirements?
No. The length is fixed.
7. Can LED flexible filament work in water?
No. But you can DIY by yourself and put the LED filament in a sealed transparent plastic tube to make it work in water.
8. What is the CRI of the LED flexible filament?
CRI≥80
9.What is the maximum current of the 38mm LED flexible filaments?
maximum current must be ≤50mA
10. How do I light up the LED flexible filament?
Connect two AA batteries in series = 3V to light up the filament. Or use a 3V button battery CR2032. You will find what you need in our battery and enclosure collections.

MC4 connectors are single-contact electrical connectors commonly used for connecting solar panels. The MC in MC4 stands for the manufacturer Multi-Contact and the 4 for the 4 mm diameter contact pin. MC4s allow strings of panels to be easily constructed by pushing the connectors from adjacent panels together by hand, but require a tool to disconnect them to ensure they do not accidentally disconnect when the cables are pulled. The MC4 and compatible products are universal in the solar market today, equipping almost all solar panels produced since about 2011.
