They are all failing like that.

May all the great lighting technologies have their place in history.

probably lost vac. the seals are poor. What a great way to help force LED junk---make fluorescent lamps that fail completely LONG before normal EOL. Also, using only a tiny amount of emission material on the cathodes hastens early failure, too--PL and PLC type lamps come to mind. I have been using the BAYCO brand at Wal-Mart, 7000K 13 watt PL lamps, a generic Chinese lamp, lately---love the crisp color of the 7000K, and they actually seem well made! I also have some Eicko 4100 K 7 watters, and these last and last, also Chinese--go figure! the ones got at Harbor Freight seem to be JUNK---13 watt 4200K, and one failed to complete black ended EOL in 8 hours! the lead wires are inserted into the base pins with no punching, crimping or soldering insuring contact issues, and when U opened the base the starter, lamp leads and leads to the pins are twisted together with no crimp sleeves or solder! JUNK! Anyway, yeah looks like lost vacuum here, Dave. Rick.

Come to think of it. Many of this particular type have brownish end bands, indicates contaminated fill gas.

Brownish end bands could be the phosphor mix too. When I was in college,the hallway lights were single 40W fluorescents. There were many brands but I noticed that the Luxor Vita-Lites would have brownish end darkening. I also have a Philips Westinghouse F15T8 5000 Ultralume in one of workshop desk lamps that brownish end darkening.

These blobs could be mercury amalgam blobs. It let's the companies to skimp with mercury more precisely.
