Two ways to select good quality LED fluorescent tubes
At present, the LED industry is quite chaotic, with defective products rushing into the market, and a large number of cheap LED fluorescent lamps appear, making consumers a bad choice.
The author tells you 2 ways to distinguish true from false
1. Prepare 2 kinds of cheap small instruments, one is a power meter that can test power, and the cheap one can display power and has a power socket.
The second is the illuminance meter
2. How to identify?
First, test whether the power of the led fluorescent tube is accurate and whether it is consistent with the label. A lot of power is not enough
Again, test the illuminance value of the led tube at a height of one meter (in a dark place), the larger the value, the better
3. Find 2 more samples for testing, and the inferior products will immediately appear in their original form.
Benwei good quality lamps welcome you to compare and test
The advantages of Benwei brand led fluorescent tubes are as follows:
1) The light distribution technology expands the LED point light source into a surface light source, and uses imported brand material PC cover to increase the light-emitting surface and eliminate visual fatigue;
2) Use ultra-bright LED light source, Taiwan brand LED lamp beads, and high-efficiency power supply;
3) Long life span of more than 50,000 hours.
4) The led fluorescent tube has low heat and is safe and reliable. Surface temperature≤50℃ (when ambient temperature Ta=25℃
5) The power supply components are imported brands, with a wide voltage range, and are universally used in the world. 85V~264VAC full voltage range and constant current, to ensure that the life and brightness are not affected by voltage fluctuations;
6) Reduce line loss and no pollution to the power grid. Power factor ≥ 0.9, harmonic distortion ≤ 20%, EMI conforms to global indicators, reduces the power loss of power supply lines and avoids high-frequency interference pollution to the power grid;
7) Universal standard lamp holder, can directly replace the existing fluorescent lamp
8) Test led fluorescent tubes, the results show that the parameters and quality are due to other brands of led fluorescent tubes in the same industry.
