The LED highbay. Just a few years ago LED technology could not produce a reliable LED configuration to compete with T5 or 400 watt Metal Halide output. Those days are gone!
James Lighting has a new LED highbay offering that boasts some very impressive numbers when it comes to lumen output.
A typical 400 watt highbay produces 20,000 lumens with a brand new lamp. However, that number quickly decreases due to the poor life of metal halide. so lets assume the lamp is running at 70% output(most places I have been are far wore than that). That takes us down to 14,000 lumens, all while consuming 456W of electricity.
The LED fixture produces 18,000 Lumens while consuming a paltry 213W....thats a 54% reduction in operating costs!!! Not to mention that the LED fixture maintains 92% of it's output at 60,000 hrs. and has a rated life of 100,000 hrs!
By the way, you can also do motion sensors on LED. Cutting costs even more!
