How to judge the quality of outdoor floodlights?
LED outdoor floodlights continue to grow into our days. At the same time, the identification of the pros and cons of LED floodlights has become our priority. The reliability of LED lighting controllers is one of the most important aspects of the control system. In part, the reliability of the key equipment, circuit design and maintenance methods of the controller will directly affect the safety and stability of the LED flood light.
To identify whether a floodlight is quiet or not, you need to take it in your hand and carefully inspect 3 aspects: is the contact between the lamp cap and the plastic part tight; is the contact between the lamp tube and the plastic part of the lower shell reliable; the upper shell plastic part and the lower shell plastic Whether the card position of the parts is fastened and whether it can be left under high temperature; whether the shell plastic parts are made of flame-retardant and high-temperature resistant materials; whether the frame and circuit board in the electronic ballast circuit are made of flame-retardant materials.
Good energy-saving lamps have an average life span of more than 5,000 hours, while poor products have an average life span of about 1,000 hours. Some even burn out the whole batch after 20 minutes of lighting, and the life span is less than a candle.
Luminous flux, luminous decay and light effect. These are the three purposes of reflecting whether an energy-saving lamp product has an energy-saving effect.
After testing the LED flood light, I learned that the same module, under the premise of good heat dissipation, the light efficiency of the 20W module is as high as 150lm/w (cold light effect), that is to say, if the heat dissipation design is very good, then The luminous efficiency of the 200W module is as high as 150lm/w
