Based on these 2002 NEC articles this cord connected light should be allowed:
The light is an appliance (Art100 defines an appliance as "Utilization equipment...").
The appliance is designed and listed and therefore intended for cord connection (Art400.7(8) specifically says "...the appliance is intended or identified for flexible cord connection.").
The restriction against cords above ceilings as found in Art400.8(5) is not pertinent because the entire Art400.8 is not applicable (Art400.8 says "Uses Not Permitted. Unless specfically permitted in 400.7...")
