Is there a requirement other than 410.4(E) that requires jacketed lamps in a facility. A local jurisdiction has required jacketed High Pressure Sodium bulbs in a warehouse to have jacketed lamps and I am trying to find if this is local or a code I have missed. I want to make sure if there is a code change that I am aware of it and enforce it equally in my jurisdiction. Thanks for the help
 
There is no such thing as a jacketed high-pressure sodium lamp. You would have to use fully enclosed fixtures. But I don't see the point of that.

The code requirement stated is there because MH lamps can explode if operated past their rated life. This doesn't happen with HPS.
 
the term of " jacketed " bulbs they are useally found in metal halide bulbs but they are kinda pricey by the way.

yes the nec did have that code came up not too long ago it started on 05 cycle

There's 410.73(F)(5), but it is for metal halide lamps.
Click to expand...

the other thing you have to watch out is the open "lumiaire" socket set up they have diffrent base concat if i recall it right they have pink socket it is rated for open socket verison for other type you have to check the bulbs rating and type most useally are enclosed type

I hope this can help a bit here


Merci , Marc
 
The requirement may be coming from the insurance company. We had to provide jacketed (enclosed) metal halide lamps for a plant that had cardboard and garments in storage in the warehouse. This was an insurance requirement.
Have not seen jacketed HPS lamps. As has already been said "Metal Halide lamps can have a dramatic end of life event." (They blow up)
 
According to the Sylvania catalog, HPS lamps may also rupture if used with the wrong ballast.

inspector 102,

You wrote that these HPS lamps are in a warehouse.

Are food stuffs stored in this warehouse?

If so, this may well be a health code requirement.
