High Bay Lights

“This led to the development of high bay lighting. Luminaires for spaces with very high ceilings, such as warehouses, factories and gymnasiums”

Rooms with very high ceilings are difficult to illuminate using standard ceiling lumiaires. Only an excessive amount of downlights can illuminate the working surface. Such a solution would be expensive to supply, install, operate and maintain. 

High bay lights used large lamps and large reflectors to illuminate a large volume of space. Warehouses in particular with tall shelving need the vertical illumination. It is important in gymnasiums and factories to have uniform lighting in both the horizontal and vertical planes. 

Until recently this was only possible through the use of high pressure sodium, mercury vapour, or metal halide lamps. Although these large powerful lamps could produce the lumens needed for high ceilings. There were many drawbacks to this technology: 

Gas lamps have an inherent warm up time. Meaning that illumination is not instantaneous. This is particularly problematic in industrial settings if a circuit is tripped and the lights go out. There will be around 10 minutes for the lamp to cool down before it can re-strike and provide lighting again. Gas lamps have a fixed colour temperature and it is not possible to dim gas lamps. There are some with so called “step dimming” where the output level can be halved, but as a rule dimming is not possible. Not to mention the chemicals used in the gas discharge lamps, their energy efficiency, and presence of both UV and IR light. 

As high output LEDs have become a reality, incorporating them into high bay lights is now possible. Enabling high bay LED lights to replace their gas lamp predecessors. 
High Bay LED Lights
 

High bay LED lights provide all the benefits of conventional high bay lights, minus the drawbacks of of gas discharge lamps, and the advantages of LED lighting technology. 

As the light distribution curve for LED’s is often part of the LED itself, there is no necessity for large reflectors. Significantly reducing the profile size of the luminaire. The range of lighting distribution options is also more comprehensive than with traditional high bay lights. A downside of the large discharge lamps was the ability to control the beam angle with precision. This is no longer an issue with LEDs as the point source has an integrated distribution curve. This technology, paired with LIGMAN MicroVOS™ for custom light distribution, improves overall efficiency. 

Whilst gas charge lamps had fixed colour temperatures dictated by the lamps composition, high bay LED lamps have control over the colour temperature. Depending on the final application, high bay LED lights can be either warm white 3000K or neutral white 4000k. 

What could potentially be the most advantageous aspect of high bay LED lights over conventional high bay fittings is lighting control options. 

High bay LED lights can be dimmed, switched with motion sensors, and monitored with advanced lighting control systems. This offers many advantages for the end user of a facility with high bay LED lights. High Bay LED lights can be dimmed during periods of low or no activity, with output being raised when movement is detected. Individual addressing enables control over specific areas of an installation and more flexibility in areas that are regularly redesigned. Enabling warehouses and industrial facilities to easily change how the lighting operates without the need for rewiring. 

The life cycle of LEDs has from the beginning also been a selling point for this technology. The longer life times of high bay LED lights means maintenance times are reduced, which provides many savings for the end user. 
High Bay LED Lights Installation 
 

LIGMAN’s flagship high bay LED light is the POWERVISION. Available in three different installation versions: recessed, surface mounted, and under canopy for service stations. LIGMAN MicroVOS™ (Micro Variable Optical System) technology enabling customers to specify tailored optics is available on all POWERVISION High Bay LED luminiares. 

King George V School in Hong Kong uses surface mounted POWERVISION luminaires in their theatre gymnasium. Suspended from the apex ceiling, they provide high levels of uniform light throughout the space. The ability to dim these high bays enables more versatility in this space. Traditional high bays would need to be lit at 100% or switched in banks, resulting in uneven lighting. 

Göritzlehner SKODA is a garage company who specialise in semi-trailers and trucks. Surface mounted POWERVISION luminaires provide the high levels of lighting needed to safely service their vehicles. The high bay LED lights provide enough illumination to supplement the outside daylight for a uniformly lit working environment.
