![]() Combined with less weight and high efficiencies, it's easy to see why they are taking off in popularity.Ĥ. Sending all the light straight down also improves its usefulness. With the new technology the LEDs can send the light down at 60/90/120 or whatever degree you need, so no need for a reflector. They are called UFO, well, because they look like spaceships of course. Classic high bays are still the standard, but the newer LED High Bay UFO Lights styles are quickly taking over. Targeting this range gives you the best mix of cost savings now and energy savings over time.ģ.Third step is Fixture. Where just a few years ago 80-100 lumens per watt was normal, today most fixtures are 120-130 lumens per watt. With Title 24 in California, you often have to use a dimmer.Ģ.Second step is Watts. This ensures they never have to send a light back. Many contractors just go higher on the lumens and just use a dimmer. Many of the high bay fixtures are also dimmable (read our article on 0-10v dimming to learn more) which can reduce energy further and optimize light levels. Turn one light on and see what it produces. In a LED retrofit, starting with a lumens meter is the best plan. Higher lumen fixtures are still fairly high priced, so using more fixtures at lower levels tends to be a better option. How many lumens does my project need and how many luminaries do I have to get there? Currently the 10,000 to 26,000 Lumens level is the most cost competitive. So now that you are sold on LED High Bay Lights what to look forġ. ![]() The choice to go LED High Bay is obvious. ![]() Navigant Research also notes that LED innovations are changing our expectations of light quality in commercial lighting spaces "while minimizing contrast, diminishing glare, higher CRI and lower energy use." Or in other words, the engineers have improved the quality of LED lights far beyond other alternatives in both light quality and efficiency. LED technology is no longer cutting edge and has proven its reliability and thus gained the needed mainstream acceptance This is propelled principally by the rising reception rates of LED luminaires in new development and retrofits. Navigant Research project worldwide sales of LED high bay lights will continue to grow for the next 5 years, coming to about $17.0 billion in sales in 2019.
