Precautions when purchasing:
1, LED floodlight brightness (MCD) is different, the price is different, the more LED lamp beads, the greater the brightness, the natural price is not cheap, the general LED lamp bead is also a high-tech product, in order to ensure the follow-up floodlights The stability of the use process, it is recommended to choose a regular brand manufacturer to buy LED floodlights.
2, the anti-static ability is also considered, the anti-static ability of the LED, its long service life, and therefore high price, usually anti-static than 700V LED can be used for LED lighting.
3, the same wavelength of the LED, so the color is the same, this kind of LED floodlights natural price is more expensive, if the LED floodlights are required to have the same color, the price will be higher.
4, leakage current is also very important, LED floodlights are unidirectional conductive illuminators, if there is reverse current, it is called leakage, LED leakage current is large, its service life is short, the current is slightly larger, you can burn Bad lamp beads, so the price of this type of LED floodlights is relatively low, it is recommended not to buy this type of lamps.
5, the lighting angle considerations, LED lighting angle is different, its lighting effect is not the same, the natural price is not the same, the general special lighting angle, the price is higher, no matter whether you want to buy LED floodlights have such requirements It is recommended to consider this factor in the purchase process.
6, the consideration of the chip factor, the illuminator of the LED floodlight is a wafer, the price of the different wafers is very different.
The wafers in Japan and the United States are relatively expensive. Generally, the price of wafers in Taiwan and China is lower than that of Japan and the United States (CREE), and the size of the wafer also affects the illumination of LED floodlights. Generally, the quality of large-wafer LEDs is better than that of small wafers.
7. The colloid is a factor that must be considered in the LED floodlight purchase process because it is related to the longevity of the life of the floodlight. Generally, the colloid of ordinary LED is generally epoxy resin, and the high-quality outdoor LED Lighting should be UV and fire resistant, so LEDs with UV and fire retardant are more expensive.
If LED floodlights are used outdoors, it is recommended to choose LEDs with UV and fire retardant when purchasing.
