Efficient LED light sources are changing the way we see elevated lighting in warehouses and distribution centers( for shop or factory), but there are some important factors that cannot be ignored. This seemingly difficult task, in fact, as long as know the most basic choice of which type of lighting to use to the most complex type of light distribution, it becomes a handy project.
Whether it's a new warehouse lighting project or a replacement project, you must know these
1. What type of lights should be used, UFO or Linear high bay lighting?
Light fixtures for warehouse lighting are available in two shapes, usually need identification and selection. UFO high bays lightfixtures are used to replace traditional metal halide(HM) or high-pressure sodium(HPS) lamps, for more wider and higher ceiling warehouse. Most of them have IP65 rated to combat harsh environments. To replace fluorescent lights, T5HO or T8 highbays, led linear high bay fixture was designed with cast rectangular beams. They will effectively distribute light in areas such as aisles and long workbenches which below 35 feet and not need waterproof.
2. How much light efficacy for warehouse need?
If your warehouse has a skylight, you can use lamps with lower light efficacy, generally, 130lm / w is enough. However, if a warehouse with a skylight only needs to open a part of the luminaire on a sunny day. It can be designed to connect the luminaire to multiple switches and open any number as needed. Since the color of the ceiling and walls affects the lighting efficiency, the light color will have higher reflectance than the dark one. If you have lighter colored ceilings and walls, this means you can also use the low light efficacy fixture.
3. What CCT to create higher productivity?
The choice of color temperature does not seem important to lighting warehouse, but in fact, it has an impact on product visibility and employee motivation. For a warm light like a color temperature of 3000K, what would it be like when used in a warehouse? The light from the luminaire looks orange, which undoubtedly changes the color of the product itself and makes the employee lazy. The color temperature between 4000K and 5000K is the best choice for the warehouses. Cool white can help ensure the color of the goods, reduce visual fatigue and increase productivity.
4. How to avoid glare?
LEDs do not work like traditional HID sources, and the intensity of each chip can be a serious problem. In particular, operators have to look up the surface of the luminaire. Just as forklift drivers need to stack products on higher shelves， they will feel glare. Therefore, it is especially important to balance the efficacy and visual comfort of the lamps. How to balance? First of all, you should lay out the interval of the lamps. If the distance is too close, the light will overlap, and too far will produce dark spots. Unreasonable lighting layout will make the operator on the head feel dizzy, so please remember to think for the operator. Alternatively, the lights can be equipped with a pc reflector to alleviate its lightness.
5. Which light distribution type will be more suitable?
It is not necessarily full of shelves in the warehouse. For open areas and wide inter-shelf corridors, we would recommend a wide beam angle of 90° and 120°. For narrower areas and elongated shelf corridors, choose a narrow beam angle of 60° or long beam angle 120°（linear high bay). This long, narrow light pattern ensures that all light is not lost by the top of the shelf.
6. Which lights do not flicker?
Some conventional light sources, such as fluorescent lamps, have a higher CRI. But because these technologies are AC powered, they can flicker, which can cause eye strain and headaches. The LED driver converts AC to DC, which means no flicker will occur.
7. Optional: Intelligent Control
If you think that high bay led fixtures are always lighting to waste energy costs, perhaps adding microwave sensor or daylight sensor is a good way to save. What is a microwave/motion sensor? This sensor automatically monitors whether someone in the warehouse is moving to turn the light fixtures on or off. What is a daylight sensor? It is suitable for areas where the lamp does not need to turn on every time you enter. For example, your warehouse has a skylight, and when the weather is fine, the skylight can bring you some lighting. You can choose the daylight sensor if you don't want to turn on the luminaire under such circumstances.
Warehouse lighting case study
After reading the above 7 knowledge points, maybe you still have questions: How should I communicate the project information to the supplier? If you are a new warehouse lighting led project (whether commercial or industrial), you may want to consider a little more, including which installation method you should choose, how to get the average illumination, etc. Please try to provide information to your supplier in this way (like a calculator).
|Warehouse size||80*140 square feet|
|Ceiling height||20 feet|
|Average illuminance||No request|
|Fixtures quantity||No request|
|Beam angle||No request|
|Shelf spacing||10 feet|
|Installation||O hook/U bracket/Pendant install|
|Smart control||Motion sensor|
Product: 100W UFO highbay star4 with built-in motion sensorThe solution suggestion provided by XSY lighting is as follows
- Layout: 6pcs*4rows=24pcs
- Beam angle: 120°
- Average illumination: 237 (Unit: Lux)
The above table is based on detailed conditions. The more detailed the content provided by the customer, the better the solution will be. At the same time, detailed information can also save the communication costs of both parties, allowing customers to get a satisfactory solution faster. However, please also trust our professional team, even if get limited data, we can design perfect high ceiling lighting solutions.
Although we would recommend led high bay lights to be the most suitable for warehouse lighting, if you want to find other types of lamps, then vapor proof lights, led strip lighting fixtures, led tube fixtures can. XSY experienced team can easily run different options with our commercial&industrial warehouse lights and provide you with the right information and guidance. We are here to save you money by the switch to LED. But it is also important to set the lighting correctly. Not sure what kind of lighting solution you want, it doesn't matter, we will design for you. Contact us: [email protected]
