This is a Philips manufactured 8W CFL, a latest model with spiral tube. An examination to quick dispose the bulb itself to look at the problem when it was no longer function.
Soldering supposed to be, but this broken CFL had a soldering joint missing, the soldering pad even still in pure color as copper, it suggests a simple conclusion but straight foreward, the worker did not solder this crucial joint!!
This soldering joint is the AC input terminal for power rectifier, we don't know how the bulb went through the inspection of quality control in their factory, but it definitely an escapee of non-conforming product. It sounds a very much concern about the quality control by Philips or her subtractor. Do we be able to claim Philips or get the money back?!
before open this defect CFL, compare with other CFL in size, the most right one is this 8W CFL, a really compact size, but the life time is also so "compact", less than a year.
visual the bulb, tube-end had been turned in black, it means the
tungsten filament inside had vaporization or broken after burn out.
this tube usually no longer breakdown for lighting.
the nickel plated cap is very much shinny, no sign of dust or corrosion
open the housing. the housing itself was turning into no longer pure white, the typical aging color of white housing by overheat
extracts the ballast inside
visual the PCB and the component
try to locate traces and broken part if any
almost there,
yes, this is faulty, no soldering
Product catalog is available to registered user at Philips lighting website, however, this latest series - Tornado CFL is not listed yet by 2007-2008 eCatalog. Around mid of year 2008, Tons of TV commercial advertisement in Taiwan as since Tornado series had been marketed.
There is another discussion for spiral tube CFL.
