NEMA, the association of electrical and medical imaging equipment manufacturers, says it's T5 lamp shipments index rose 41.1% since a year ago. The index reclaimed lost ground from the previous quarter, rebounding by 19.8%. T8 lamp shipments also grew strongly, rising 12.7% year-over-year. Conversely, shipments of T12 lamps declined 2.6 and 7.9% 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% of sales, down 5.1% from the 2009 average. T8 lamps rose to 65% of sales, 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%. These market share trends are likely to continue because of the July 1, 2010 completion of the phase-out of T12 magnetic ballasts.
