Craig DiLouie August 20, 2015

NEMA’s shipment indexes for high intensity discharge (HID) lamps continued to decline at the start of 2015.

Sodium vapor lamp shipments fell 11.5% on a seasonally adjusted basis compared to the same period last year. Shipments of mercury vapor lamps retreated by 18.4% year-over-year (y/y). Although the index for metal halide lamps registered a modest year-over-year increase of 1.2%, shipments were still below the level during calendar year 2014.

Sodium vapor lamps gave back 2.4 percentage points, decreasing to a share of 30.1%, while mercury vapor lamps declined marginally to 3.5%. The market share of metal halide lamps increased to a new high level in the series, at 66.5% for the quarter.
