Waterproof is good, if the seal is done well, it is not easy to enter the water, that is to say, the waterproof performance is good, as long as the lamp housing is good, plus a good sealing strip, it must be IP65 or above. 100w outdoor slim led floodlight light outdoor with rain, moisture-proof, soaked into the water for a long time there are safety hazards, it is recommended to use professional lighting in the water, such as underwater lights, buried lights, etc., this package is tight. 4. Look at the power supply, it may be taken apart to see the power supply. Some manufacturers do not add a waterproof epoxy resin to save the cost. The power quality, the lamp bead is small, and the current output from the constant current source is also small. The constant current source is assembled from many electronic components. The average manufacturer purchases at least several hundred thousand each component each time. Ageing and testing are performed on imported equipment after assembly. Each constant current source is subjected to high temperature and low temperature tests to eliminate unqualified components. Regular manufacturers will not produce such inferior constant current sources. LED luminaires must be equipped with high quality, high efficiency drive power. The life of the power supply directly affects the overall life of the luminaire. Specifically, consult the various parameters of the driver about the drive, such as output voltage and current, operating temperature, etc. 100w outdoor slim led floodlight power supply is to do glue waterproofing, we have even seen some manufacturers in the power supply Saisa to fool consumers. Take 30W LED power supply, there are more than 10 pieces, there are more than 30 pieces, which is actually a lot of famous. Look at the craft; The quality of the whole lamp and the power supply of the lamp, the light source and the sealing strip, the thickness of the cable, the use of the thermal grease, the craft level of the worker (care level, welding process) and so on. . .
