Comparison Of LED Street Lights And Metal Halide Lights

1、Type Of Light Source

Metal halide lamps are hot light sources; LED street lights are cold light sources.

2、Excess Energy Dissipation Form

Metal halide lamps dissipate excess energy through infrared and ultraviolet rays, but infrared and ultraviolet rays will affect product quality and affect human physiology;

The LED street lights generates heat through the light source device, which consumes excess energy, and the heat conduction is very easy to control.

3、Lamp Housing Temperature

The temperature of the metal halide lamp housing is very high, which can exceed 130 degrees;

The temperature of the housing of the LED street lamp is extremely low, normally below 75 degrees. The decrease in the temperature of the LED housing can greatly increase the safety and life of cables, wires, and supporting electrical appliances.

4、Vibration Resistance

The filaments and bulbs of metal halide lamps are easily damaged and have poor vibration resistance;

The light source of the LED street light is an electronic component, which is inherently anti-vibration. LED lamps have unparalleled advantages in vibration resistance.

5、Light Distribution Performance

The light distribution performance of the metal halide lamp is difficult, the waste is large, and the spot is uneven. It requires a large reflector and the lamp is large in size;

The LED light line is very easy to control, and it can achieve a variety of light distributions under the same volume, and the light spot is uniform. The convenient feature of LED light distribution can greatly save the waste of lamps in the light distribution and improve the luminous efficiency of the lamp system.

6、Anti-Grid Voltage Interference

Metal halide lamp: Poor, the lamp power changes with the fluctuation of the grid voltage, and it is easy to be overloaded;

LED street lights: stable, constant current power source drive can keep the light source power constant when the grid voltage fluctuates.
