    NEC 410.62.C Electric Discharge Luminaires

    Reading, 410.62.C Cord Connected Installations of Electric Discharge (and LED in 2011) Luminaires, I have become very concerned that this will significantly limit the use of many LED and Fluorescent fixtures. Is this how others read this or am I overreacting?

    Most specifically troubling is the line:, "The luminaire is located directly below the outlet or busway"

    Wouldn't this disallow the use of:
    --Cord connected fluorescent or LED undercabinet lighting (since it would be impossible to locate the receptacle 'directly above' the fixture.)
    --LED cove systems such as this: http://www3.traxontechnologies.com/u...details/10356/
    --Any LED, MH or Fluorescent theatrical/intelligent fixture from a theatrical connection box (where it would be impossible to fit 4-6 fixtures directly under the box)
    --Any LED or Fluorescent table or floor lamp that is plugged into the wall.
    --Low Voltage LED Landscape lighting (the resi stuff)

    I know that many of these sound ridiculous, but the code wording appears to be so broad that many installations would be non-compliant.
    Thoughts?

    Yes it would and most undercabinet lighting that we use is direct wired. IMO, If there is a driver for the led then that may be located remotely with an approved wiring method to the fixture.

    Same as above- not an issue
    --Any LED, MH or Fluorescent theatrical/intelligent fixture from a theatrical connection box (where it would be impossible to fit 4-6 fixtures directly under the box)
    Good question, not sure
    --Any LED or Fluorescent table or floor lamp that is plugged into the wall.
    No, the NEC does not cover table lamps and has no control over where they would be installed
    --Low Voltage LED Landscape lighting (the resi stuff)
    Again the led's I see are direct wired or have remote drivers- not an issue
    They say I shot a man named Gray and took his wife to Italy
    She inherited a million bucks and when she died it came to me
    I can't help it if I'm lucky

      Theatrical lighting would be covered under Article 520 so 410.62 would not apply.

        Remote Drivers and Approved Wiring Methods

        Thanks for the replies,

        With a strict reading of the code, how would you justify remote drivers wired and approved wiring methods? I just don't see these exceptions.

        There are also a number of products that have line voltage LED, with integral drivers) the cove lights that I linked in the OP have integral drivers, but have 120V flexible wiring to and between units .

        There are a number of under cabinet lights that are line voltage flexible cord fixtures with drivers integral to the lighting units (from cheap manufacturers at Menards all the way up to higher end Alkco, etc).

        Ever since the city electrical inspector dinged me on my plug in shoplights at home (made me relocate them so they were directly under the receptacles), I've been leery, in my day job, of specifying many of the LED fixtures on the market. Just not sure if I am missing something or misinterpreting...
