Since 13-may -2010 , We have adding aging 14V 5 min process ( Process No. ⑧ ) for take foreign matter stick filament for detect filament broken which cause from foreign matter stick filament But aging by operate electricity rating 14V 5 min for
this part no.75D555-0160 it take filament's row material is tungsten will be change it have crystalization it too easily for broken
Refer lamp was take aging 14V 5 min filament's surface had been change which it easily to broken more than lamp do not take aging 14V 5 min ,This reason we would like to stop aging 14V 5 min for TRT Part no.75D555-0160
urgently!
