1000W Metal halide high bay:
Color temperature: 4500K
Lumens: 1000 watts, 80,000 lumens (Philips)
Light efficiency: Because the metal halide light is usually 360 degrees light, there is a lot of light blocked in the vertical installation, so the overall lighting efficiency is very low
Lifespan: 30,000 hours, 6 hours a day, 10 years
The bulb of the IP65 metal halide lamp is extremely high in temperature, because its luminous efficiency is not affected by temperature, so in order to increase the temperature of the bulb, quartz is used instead of glass. In the future, quartz is replaced with transparent ceramics.
In fact, the biggest drawback of the metal halide lamp is that it needs a ballast besides the mercury, because its starting current greatly exceeds 15A, and it requires a high starting voltage, so the most commonly used is to use a large inductor like a fluorescent lamp. As a result, its power factor PF is very low, about 0.5. If you want to increase the PF, you must use a better, but more expensive, electronic ballast. The price of ordinary type inductance ballast is 65 RMB, and the price of energy-saving type inductance ballast is 80 yuan. The price of electronic ballasts is hundreds of RMB.

Comparing the features of the two lamps, although the luminous flux of the 1000W metal halide lamp is higher than 350W LED linear high bay,but the 360° light emission of the metal halide lamp causes a waste of light. The LED is a straight-illuminated light source with an angle of only 120°. Used with a lens, the light utilization rate is higher than metal halide lamp. We can get illumination similar to or higher than a 1000W metal halide lamp.So 320 watt LED high bay is HID 1000w high bay LED replacement.
