T5 lamp shipments index registered a reading of 152.0 during the second quarter of 2010, a 41.1 percent increase from a year ago, according to the National Electrical Manufacturers Association (NEMA), Rosslyn, Va. The index reclaimed lost ground from the previous quarter, rebounding by 19.8 percent. T8 lamp shipments also showed robust growth, increasing 12.7 on a year-over-year basis. Conversely, shipments of T12 lamps declined 2.6 and 7.9 percent for the quarterly and year-over-year comparisons, respectively.

The share of T12 lamps in the linear fluorescent market also declined. T12 lamps accounted for 26.3 percent of sales, 5.1 percentage points below the 2009 average of 31.4 percent. T8 lamps increased to a 65.0 percent, a half point below its all-time high. The portion of the market held by T12 lamps grew to a new high of 8.7 percent. These market share trends are likely to continue due to the July 1, 2010 completion of the phase-out of T12 magnetic ballasts.
