We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.

1. According to the terminal label, the signal source output is marked with a red mark U+ output is connected to the positive power supply of the DC bus, and the U-output terminal marked with a yellow mark is connected to the negative power supply of the DC bus (do not connect wrong). .
2. Close the AC power switch of the signal source, close the output signal switch, and the signal light flashes. The output terminal has the low-frequency signal output.
3. After the check signal light is on, connect the device ground to the ground of the system under test.
4. Select the signal amplitude switch correctly, use the signal amplitude U when the bus uses -220V, -110V DC power supply, and use the signal amplitude 1/2U when the bus uses 48V DC power supply.
5. Turn on the power switch on the side of the caliper and use the probe caliper table card to measure the positive or negative circuit of each outgoing line one by one on the circuit under test. The indicator on the card table has a clear indication that the fault point is in this loop.
DC grounding device precautions :
1. According to the operation step by item, you must not reverse it.
2. If it is found that the indicator light is off after the U+ and U-DC power supplies are connected, check the device and remove it before using it.
3. The detector caliper should be more than 0.5 meters away from the signal source to avoid affecting the accuracy of the measurement.
4. When replacing the receiver battery, simply turn on the power box at the bottom of the header to switch it.
5. Connect the U+ red line to the DC bus anode and the U–Yellow line to the DC bus cathode.
6. After the signal source is connected to the DC bus, the signal source does not need to move until it is found faulty and then removed. The measurement only needs to move the caliper table position one by one to find the fault.
