toxic materials is high, especially for outdoor led lights. Don't use cheap led lights with odor. At present, only a few LED manufacturers use non-toxic materials to produce. The method of identification can be directly used for the nose, and the products with odor are much lower than the price without odor. Toxins like lead, mercury, and cadmium require professional analysis. From the perspective of applicable environmental safety, there is a reliable dustproof and moisture-proof design, and the price of led products for fireproof, ultraviolet protection and low temperature cracking is high.
Now teach everyone how to choose the 400w Led Flood light. There are several places to note:
1, led brightness is different, the price is different. The led for LED lamps should be suitable for the laser class I standard.
2, strong anti-static ability led, long life, and therefore high prices.
3. The LED with the same wavelength has the same color. If the color is consistent, the price is high. It is difficult for manufacturers without led spectrophotometers to produce pure color products.
4. Leakage current led is a unidirectional conductive illuminator. If there is reverse current, it is called leakage, and LED with large leakage current has short life and low price.
5, the lighting angle of the use of different LEDs, the light angle is not the same. The specific illuminating angle is higher in price.
6. The key to different quality of life is life, and life is determined by light decay. Low light decay, long life and high price.
7. Wafer Size The size of the wafer is expressed by the side length. The quality of the large wafer led is better than that of the small wafer. The price is proportional to the size of the wafer.
8, colloidal ordinary led colloid is generally epoxy resin, plus the anti-ultraviolet and fire retardant led price is more expensive, high-quality outdoor led lighting should be resistant to UV and fire.
