How to replace 400W Metal Halide with LED High Bay
The difference between LED high bay and conventional high bay at lighting distribution. I quote some below information from CREE high bay design reference.

Pic 4: typical LED chip light distribution
Firstly, metal halide lamp lighting distribution is very spread to the air. So it needs a high and deep reflector to reflect the light to the ground. But the reflection rate is very low and lots of lumens have been wasted. But LED is very directional to ground. Philips make both of conventional Metal Halide High Bay and LED High Bay themselves. They know exactly how is the conventional high bay performance. So I quote the information from the datasheet of Philips LED High Bay also. The replacement vary based on it's a new project or a retrofit project. If it's a new project, Philips high bay at least can save 44% energy comparing with the best performing conventional highbay. Some Metal Halide bulbs have very high lumen output, but the useful lumens for a fixture and downward to the ground is very limited. And some Metal Halide fixture bulb is not so high efficiency as advertising at all. Such as the HPLN lamp type one actually only has 16500 useful lumen at max. Please keep in mind that this comparison data is based on

If it's a retrofit project, again two years old highbay. It can at least save 53% energy.

Conventional High Bay LED High Bay This comparison picture is from Philips high bay data sheet. Philips Lighting Spec:
HiCloud High Bay Lumen test report:
HiCloud LED High Bay Lights Compare with Philips GreenPerform High Bay.
HiCloud GreenPerform
Item HC-A150 BY688 LED160
System Wattage 150W 160W
Lumen Output 17800lm 16000lm
Lumen Efficiency 119lm/W 100lm/W
So comparing with Greenperfrom, HiCloud High Bay could save extra around extra 19% energy. Do you think HiCloud LED high bay could replace 400W Metal halide right now? If you have other questions, welcome to contact us: E-mail: [email protected] Website: www.okled.com
