In the realm of industrial and commercial lighting, the question of “How many UFO LED high bay lights do I need?” is of utmost significance. Adequate illumination is not only essential for the smooth operation of activities within a space but also impacts energy consumption and cost-effectiveness.
Beginning with the characteristics of the UFO LED high bay lights, the Coydon Lighting UFO LED High Bay light presents several notable features. It has a wide input voltage range of AC 90V – 305V, making it highly adaptable to various power supply conditions. The Color Temperature (CCT) offers three options: 3000K, 4000K, and 6000K, allowing users to customize the lighting atmosphere according to different requirements. A Color Rendering Index (CRI) greater than 80 ensures vivid and accurate color representation, which is crucial in applications where color perception matters. With an IP Grade of 65, it is well-protected against dust and water ingress, suitable for even harsh environmental conditions.
The photometric data of this light is also valuable. The luminous emittance values at diverse angles, as presented in the document, provide insights into the light’s dispersion pattern. This data, along with the luminaire classification and CIE flux code, aids in gauging its performance potential. Additionally, the fixture’s compact and sleek UFO design not only contributes to its aesthetic appeal but also plays a role in optimizing the light distribution. The unique shape helps to direct the light more precisely, reducing glare and ensuring a more even spread across the illuminated area. This, in turn, enhances the overall lighting experience and makes it more suitable for a wide range of applications.
The space in which these lights are to be installed is a key determinant. Taking Room 1 as an example, its dimensions – a height of 9.000 m and a mounting height of 8.500 m, along with a ground area of 1440.00 m² and specific wall lengths – shape the lighting requirements. The workplane height at 0.850 m and the varying reflectance values of the surfaces (20% for the floor, 70% for the ceiling, and 50% for the walls) have a profound impact on how light behaves within the room. These surface characteristics influence the amount of light that is absorbed, reflected, and ultimately distributed, affecting the overall illumination quality.
The defined lighting requirements for the space are precise. The workplane demands an average illuminance of 346 lx, with a minimum of 168 lx and a maximum of 430 lx. The illuminance quotient ratios, like the 0.489 for the wall to workplane and 0.214 for the ceiling to workplane, provide a relative measure of brightness. The inclusion of a light loss factor of 0.80 accounts for real-world conditions that can cause a reduction in light output over time.
Using the provided data, the calculation of the required number of lights becomes possible. With each luminaire having a total light output of 28675 lm and considering the ground area and desired illuminance levels, along with the light loss factor, the resulting calculated number of 24 pieces lights (as in the case of Room 1) is a practical outcome. The layout of these 24 pieces lights, as shown in the layout plan, is designed to achieve uniform illumination, minimizing dark spots and ensuring a consistent level of brightness throughout the space.

Yet, the advantages of UFO LED high bay lights extend beyond their installation. Their user-friendly design makes installation a breeze, saving both time and effort. Moreover, maintenance is hassle-free. The fixtures are engineered to resist dust and debris accumulation, minimizing the risk of light output reduction. Routine cleaning and inspections are straightforward, further ensuring the lights’ long-term efficiency and durability. This not only maintains the desired illumination levels but also maximizes energy efficiency throughout their lifespan.
Looking ahead, technological progress in the lighting industry is a constant. New and improved lighting solutions may emerge, offering enhanced energy efficiency and better illumination quality. Staying informed about these advancements and being open to upgrading the lighting system when appropriate can lead to further optimization of the lighting environment.
In conclusion, the determination of the number of UFO LED high bay lights is a multifaceted process that demands a meticulous consideration of the fixture’s properties, the space’s characteristics, and the lighting standards. By comprehensively evaluating all these elements, as exemplified by the analysis of Room 1, we can ensure a lighting solution that strikes a balance between functionality, energy efficiency, and cost. This, in turn, creates an environment that promotes productivity, safety, and visual comfort, all while making the most of available resources.
