Comparison Of 100w Outdoor Ultra-thin Led Floodlight And Sodium


    The utilization rate of 100w outdoor slim led floodlights is about 80%, and the light utilization rate of high-pressure sodium lamps is usually 40%-45%. Here, due to structural reasons, there is a reduction of 43%, which leads to easy light emission and high light utilization rate.
    Due to the poor color of the high-pressure sodium lamp, although the lumen of the high-pressure sodium lamp is slightly higher, the actual lumen that can be effectively used by the eye is about 70%, which leads to an intuitive concept of actually using lumens.
    The color of a 100-watt led floodlight can basically be used by the human eye. From this, it can be seen that the actual lumens of the 100w led lamp and the 250w high-pressure sodium lamp street lamp are basically the same. The light emitting point emits light, which can perfectly adjust the lens to the required light distribution curve. This obvious advantage is led by actual lighting effects. Can effectively avoid glare and excessive lighting. The following is a comparison between high-pressure sodium lamps and floodlights, which are relatively superior.
    1. The color of the high-pressure sodium lamp is yellow, and the color temperature and imaging index are relatively low. The sun imaging index is 100, while the high-pressure sodium lamp imaging index is only 20 (yellow).
    2. The color temperature of the LED light source lamp can be flexibly selected between 4000-7000K, the imaging index is up to 80 or higher, and the color of the lamp is closer to natural light.
    3. The bulb structure of the sodium lamp determines the low utilization rate of the lamp, only about 40%. Before reaching the designated area, the 360° luminous angle of most lamps must be reflected by the reflector.
    4. The utilization rate of the light source of the LED lamp is very high, about 90% of the LED lamp's luminous angle can be consistent with the illumination angle, so most of the light is directly irradiated to the designated area by the lamp, and only a small part is reflected, so Floodlight 100w utilization rate is high.
    5. The startup time of the high-pressure sodium lamp bulb is long, and it takes a certain time to restart. High-pressure sodium lamps need to reach normal brightness within 5 to 10 minutes of power-on, and the interval between restarts is generally greater than 5 minutes.
