    Samxon: good or bad?

    So I watching a teardown video on a phillips LED bulb here: http://www.youtube.com/watch?v=OWKAub54sLU

    Notice very clearly one of the big caps is made by samxon (and an unknown temperature rating)
    Correct me if I am wrong, but isn't samxon kind of "marginal"?
    I have a later revision of that bulb and the base part gets to nearly 80c after a few hours of run time. It seems like that might be a candidate for early failure?

    What do you think?

      I would call the 'middle grade'. They are not top-end like Nichicon, Rubycon, or Panasonic by any means, but they will typically get your device through its useful lifetime.

          OK
          Well these are suppose to be rated at 25K hours, but I kind of doubt it

              It depends on the series, too. The GF and GL series are known to be problematic, and are down there with CapXon and Fuhjyyu. Some of the others (GD, GC and RS series for instance), aren't as bad.
              I love putting bad caps and flat batteries in fire and watching them explode!!

              No wonder it doesn't work! You installed the jumper wires backwards

                  I haven't read the fine print, but a lot of light bulbs are rated for X years at Y hours per day. That might be more important for LEDs.

                  That would be really annoying to have a duty cycle on your lightbulbs.

                      By coincidence, I just ran into this article:
                      http://www.edn.com/design/components...citor-pitfalls

                      Guess polymer caps aren't in the running for these devices, at these price points - too bad.

                          Polymer caps also have a rated lifespan.

                              This is concerning. Especially with incandescent bulbs being banned
                              I guess we will find out its real life span but I am betting it won't be as much as claimed at 80C case temp

                                  TOSHIBA DLP 52HM95 How to reset timer module on bulb
                                  by repair-it
                                  I replaced the bulb only on my Toshiba DLP The bulb is a TB-25. This is the first time I've done a bulb only replacement. Supposedly there is a timer module that needs to be re-calibrated or reset. I don't know where the module is located. I see some vendors selling the bulb with the housing stating module included which leads me to think the module is located inside the enclosure the bulb mounts in, but I didn't see it. Maybe it's inside the plug attached to the bulb?

                                  Anyway - I am seeking information on how to reset this so called module so that the lamp will operate. Apparently...

                                  LUMIMAN Smart Bulb IC ID?
                                  by ezenia
                                  Hi,

                                  I have a LUMIMAN Smart Bulb that suddenly stopped lighting one day. The bulb is still detected in the app, but won't light. I've probed around and nothing seems to look off with any of the diodes, caps or resistors. The Bluetooth/Wi-Fi module seems to be working as it's still detected in the app. I even tried deleting and re-pairing the bulb (it didn't light, but I was still able to follow the pairing instructions), it re-paired fine, but still no light.

                                  In diode mode, the LEDs all light up when probed so I'm guessing this means the LEDs themselves are OK. I was expecting...

                                  Hi all,
                                  this unit comes from a samsumg LCD TV LE32C530F1W which stopped working after making a strong noise like something was exploded inside of it.
                                  I opened it and found that fuse FP801S was blown, capacitor CP814 was completely disintegrated and MOSFET QP801S was shorted.
                                  I replaced all of them and instead of the fuse I connected a 100 Watt bulb. Then, without connecting it to other TV boards, I switched it on, but the bulb begun to blink.
                                  I thought that maybe the bulb was somehow interfering with the normal operation of the power supply, so I replaced it with a fuse,...
