How to Select the Right LED for High-Bay Lighting


The high-bay lighting market is getting ready for a big shift to LED technology. This is being driven by the falling prices of led high bay, along with advances in sensors and controls, which are used to help further reduce energy consumption, enabling an acceptable return on investment (ROI). High-bay lighting applications in commercial and industrial environments now are well positioned to take advantage of led high bay in terms of energy savings and minimizing downtime.

Navigant Research (Boulder, CO) forecasts global sales of high-bay luminaires and lamps will increase through 2017, reaching almost $17.0 billion, propelled primarily by the rising adoption rate of more expensive led high bay and lamps in new construction and retrofits.


Navigant Research points out that led high bay technology improvements are also driving the shift, enabling LEDs to meet the tough requirements of illuminating these wide-area spaces "while minimizing contrast, reducing glare, and in many cases meeting strict safety and hazardous environment requirements." led high bay

For lighting designers to develop the most cost-effective luminaires that take advantage of led high bay technology, they need to select the right emitters for the job. These LEDs must be able to meet high-output lumen requirements while simplifying heat management and delivering the right amount of light distribution.

There are many ways to integrate led high bay into high-bay luminaire applications, and there are a number of considerations and/or trade-offs for designers that range from thermal designs (heatsinking) and optical control to driver selection and pricing. Designers of high-bay lighting systems may also want to start looking at incorporating sensors, networking, and other advanced lighting controls to further energy savings and cost reductions, but that is beyond the scope of what we are exploring here. In this article we will take a look at several LED solutions that meet the performance, as well as deliver the cost savings required for led high bay  applications
Cree recommends a six-step framework for designing led high bay luminaires and lamps (Figure 1). As part of this framework, there are six critical characteristics that designers should evaluate when designing high-bay lighting systems. These include illuminance distribution (footcandles [fc]/lux), electrical power (watts), lifetime (hours), payback (months), luminous flux (lumens), and manufacturability. Other important characteristics include operating temperature, operating humidity (percent RH), correlated color temperature (CCT) (K), color rendering index (CRI), and ease of led high bay installation.
