A customer wanted to replace mercury vapor fixtures with LED. What LED light fixture would emit equivalent levels of light?
Mercury vapor lamps ceased production after January 1, 2008, and for a good reason. As discussed in a previous blog post, Mercury vapor lamps continue to stay lit even if they don’t emit any light. They never actually burn out. Consequently, the Mercury vapor light fixture continues to remain on using 100% of the energy without producing almost any light.
If a customer were to ask how much light their Mercury vapor light fixture was emitting, it would be virtually impossible to know. Maybe some. Maybe almost none. You have to start over. The question becomes how many foot candles of light are required in the area. Knowing the size of the area to be lit and the purpose the area is being lit up for, an Access Fixtures lighting specialist can determine which LED light fixture is best and how many are required.
Here is the good news! LED sources are very different than Mercury vapor light fixtures. The light is high CRI which means objects have excellent color rendering. Also, LED luminaires maintain most of their initial light output, some maintaining 85% of the initial light output after 100,000 hours of use.
