DC LED Lighting

03/09/2017 10:31 AM

Many clients are asking for DC LED in their specifications to meet the emergency lighting requirements,in a power plant. Would like to know if any vendor is offering the same.

I am 40 years removed from the industrial/institutional building industry, so don't know the answer for sure, but in 1976 we used AC charged battery powered DC emergency lighting then. Obviously not LED, but since such fixtures have been in existence for more than 50 years, there must be LED versions by the dozens by now. Have you tried an internet search for such? I would guess not.

I am referring to the double headed battery pack lighting units we've used for 50 years, but I think I could easily install an LED/battery/charger/voltage drop sensor in a fluorescent type fixture for low ceiling areas, so surely that version exists as well. Why I think I could even install such in a high bay vapor type fixture as well. Try searching for it - if I could rig up such an item, they have to be made by dozens of lighting companies by now.

Hey Johnny: you are supposed to say, "the dog ate my homework", much less do the homework, legwork, footwork, and handwork for the OP.

LED lighting is uniquely suited for emergency lighting, because the low power draw makes for well lit hallways, plant basements, etc., not the old dungeons we are used to on TV dramas. It is apparently impossible for the hero to get in a shoot-out anywhere except two places (1) abandoned power plant, or (2) abandoned chemical factory of one type or the other, (3) cement factory (actually counts as a chemical factory IMHO).

I know, but I was feeling charitable. Sometimes that happens. By the way, it's James, not Johnny. I have a sneaky suspicion that will be easy for you to remember.

The Johnny thing was a reference to "Little Johnny" at school, not necessarily JPool. Thanks for the warning, I will make sure and remember your name.

Is this for a zoned hazardous area (gas or dust) or just plain industrial?

So the battery backed emergency exit pathway lighting is one option, but a new one offered now because of the energy efficiency of LED lighting is to change out your high bay area lighting or your old fluorescent tube lighting with 48VDC LED fixtures that have a battery backup feature either built in to each fixture or powered by centralized battery banks that allow you to ride through a transfer to a backup generator. Several companies offer this option.

There is many type of DC LED emergency light available in the market. Get the catalog and specification from these suppliers and you can compare it it with any vendor.

Is there some reason why Google cannot be used at that location to search for emergency lighting vendors?
