Which has the more Advantages, 630 watt Ceramic Metal Halide or the 630 watt LED Lamp?

The cost of 630 watt LED light source is too high, and the one-time investment is too large, which is several times higher than that of ceramic metal halide lamp; the average color rendering index (CRI) of LED is low, so the color displayed under LED irradiation is not truer than 630 watt ceramic metal halide; 630-watt LED is dazzling, which is not suitable for urban main and secondary roads and workshop lighting, while 630 watt ceramic metal halide has moderate color temperature, comfort, small glare and strong fog-piercing ability; Although there are many ways to improve the brightness of the light source, it can not increase the light distance; the practical 630 watt LED has lower luminous efficiency than 630 watt ceramic metal halide, but the initial investment cost is high with the current technology.

The 630 watt ceramic metal halide can save more energy than 630-watt LED, but the light output ratio of ceramic metal halide lamp is required to reach more than 68%, and the utilization coefficient of lamp is the same or higher as that of LED at the same time. And using life doubling technology of ceramic metal halide lamp, it can save more energy and economy than LED street lamp.
