Before using LED light, many customers used 400W metal halide high bay light. Such a high wattage has promoted an increase in electricity bills, which is contrary to the current theory of energy conservation.
This article will talk about how many wattage LED lights should be used to replace 400W metal halide high bay light.
The light efficiency of metal halide high bay light is generally very low, about 40 lumens per watt. However, through years of development of LED, the light efficiency of our UFO LED high bay light can reach 150 lumens per watt. In terms of light efficiency alone, LED lights are much better than metal halide high bay light.
Below is our product video and product list.
 | Model: | Dimension: | Input Voltage: | Power: | CCT: | CRI: | LED Type: | IP Grade: | Material: | Luminous Efficiency: | Beam Angle: | Warranty: |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
 | KD-HBD-W100-1 | Ø248mm X 129mm | AC 90V - 305V | 100 Watt | 3000K / 4500K / 6000K | 80 | LED SMD 2835 ( OSRAM ) | IP65 | Aluminium + PC Lens | 150 Lumens per watt | 60° / 90° / 120° | 5 Years |
 | KD-HBD-W150-1 | Ø295mm X 140mm | AC 90V - 305V | 150 Watt | 3000K / 4500K / 6000K | 80 | LED SMD 2835 ( OSRAM ) | IP65 | Aluminium + PC Lens | 150 Lumens per watt | 60° / 90° / 120° | 5 Years |
 | KD-HBD-W200-1 | Ø320mm X 154mm | AC 90V - 305V | 200 Watt | 3000K / 4500K / 6000K | 80 | LED SMD 2835 ( OSRAM ) | IP65 | Aluminium + PC Lens | 150 Lumens per watt | 60° / 90° / 120° | 5 Years |
| KD-HBD-W240-1 | Ø320mm X 154mm | AC 90V - 305V | 240 Watt | 3000K / 4500K / 6000K | 80 | LED SMD 2835 ( OSRAM ) | IP65 | Aluminium + PC Lens | 150 Lumens per watt | 60° / 90° / 120° | 5 Years |
Example: The length of the space is 50 meters, the width is 50 meters, and the installation height and space length are both 10 meters. The same is the number of 48 lights, calculated by DIAlux, and the following conclusions are drawn.
The illuminance of the metal halide high bay light is 881280 lumens in total, and the average illuminance is 215 lumens.
However, the total illuminance of UFO LED high bay lights is 1756560 lumens, and the average illuminance is 538 lumens.
Two test reports will be placed at the end of the article.
200W LED lights can completely replace 400W metal halide high bay light.
In customer feedback, one of the biggest problems of metal halide high bay light is that the ballast continues to fail. Every time the ballast failed, the customer had to call an electrician to repair it. The warehouse has a ceiling of about 7 meters high, which quickly becomes time-consuming and costly.
This LED light uses an aluminum shell with good thermal conductivity, which can improve energy efficiency and keep the LED chip in a low temperature state. These make the light durable and work for more than 50,000 hours. It can work normally under AC90-305V power supply.
Another major problem is the lack of efficiency and the cost of running the lights. These lights consume a lot of electricity, and the system power of each light is as high as 400 watts. Another reason for improving efficiency is that metal halide high bay light will depreciate in a short period of time or become less bright.
It can be seen from the results that the brightness of the LED light is much brighter than that of the metal halide high bay light, and the power is reduced by half, which is a good embodiment of the theory of energy conservation.
The last major issue that customers worry about is the risk of non-passive failures. Non-passive failure refers to the spontaneous explosion that may occur in metal halide high bay light. In this case, the hot glass will fall on everything nearby, and this risk is too great for the customer.
IP65 and IK08, making the lights widely applicable to dry and humid environments (garages, workshops, barns, stadiums, factories, exhibition halls, shopping malls, supermarkets, storage rooms, basements and any other large commercial and industrial places) .
Three color temperatures of 3000K, 4500K, and 6000K are provided for customers to choose from. 6000K is the most used in customer groups. This is the color temperature closest to natural light and is very friendly to human eyes. The color temperature of 4500K makes people look a little yellow, but it feels warm.
There is also a superb color rendering index, which can restore the original color of the object to the greatest extent.
So there are 400W metal halide high bay light that needs to be replaced. This 200W UFO LED high bay light is your best choice.
