Why choose LED high bay lights instead of metal halide, fluorescent, or other conventional high bay lights?
Historically, various lighting technologies were (and still are) used in warehouse and industrial settings when high bay lights were required. Some of the most common include metal halide (MH), high-pressure sodium (HPS), and fluorescent. While each of these bulbs has its merits, industrial LED lighting outperforms its conventional counterparts in important ways. Let’s take a look at some of the various considerations when deciding whether an LED retrofit is appropriate for your warehouse or industrial space. Industrial LED lighting vs metal halide high bay lights: If you’ve ever been to a ballgame, you've likely seen metal halide illuminating the field. MH lamps are common in sporting and warehouse/industrial uses (as well as any setting where large, high spaces need to be illuminated). Benefits of MH lights include decent color rendering and comparatively adequate foot-candle levels (as opposed to other types of conventional bulbs). Some of their major drawbacks are a long time to warm up (sometimes 15-30 minutes) and a high cost to maintain, and their failure characteristics include flickering on and off. This is in addition to the fact that much of the energy they produce is wasted as heat. LED high bay lighting vs high-pressure sodium (HPS) lights: HPS lights are often used in warehouse, industrial, business, and recreational facilities where high bay lighting is appropriate. Their benefits include cheap selling price, high energy efficiency (low operating costs), and a relatively long lifespan. HPS lighting technology retains these advantages over most conventional bulbs, but they lose on all three counts to LED high bay lighting. The downsides of HPS bulbs include the worst color rendering on the market and a warm-up period. Industrial LED lighting vs fluorescent lighting: Though somewhat less common, fluorescent lighting is sometimes utilized in the warehouse or industrial applications (primarily T12, T8, and T5 lights). The benefits of fluorescent lights include cheaper initial costs and relatively high efficiency (especially when compared to other conventional bulbs). Downsides include the presence of toxic mercury (which requires certain waste disposal procedures), decreased lifetime if switched on and off and require a ballast to stabilize the light.
