edit i like the idea of the generator and scope! i have a digital scope and a 10x probe

Depending on the age, the oil inside the transformer may have been a PCB (Poly Chlorinated Biphenyl) which is nasty toxic stuff, gives you cancer and makes your bits drop off (or something like that).something to do with the coolant and the value of the transformer
Here you go;dont fancy bits dropping off, but would have been good to take it apart!

i am a bit disappointed! dont know what i expected but it was more than that! still would have kept me in copper wire for a bit .
And that's one reason why thay would not give it to you. It may have 10 to 50 Lbs of copper in it.i am a bit disappointed! dont know what i expected but it was more than that! still would have kept me in copper wire for a bit .

In 2013, The International Association for Research on Cancer (IARC) determined that the evidence that PCBs cause non-Hodgkin Lymphoma* is “limited” and “not consistent.” Institutions devoted to cancer research and treatment such as the American Cancer Society and the Mayo Clinic do not list PCB exposure as a risk factor for non-Hodgkin Lymphoma.

Hello,
I believe that lifetime estimates for LED lightbulbs are farcical, because most of them are power factor corrected, and have very little capacitance on the primary side DC bus, and so are liable to receive component damage due to mains voltage transients.
..ok, this is my bad, I didn't say what the topology was..I am not speaking of led lightbulbs with a boost pfc stage. I am speaking of led lightbulbs with a flyback pfc stage.You seem to be forgetting that, while a PFC stage will have very little capacitance in front of the PFC inductor, they will have a fair amount of bulk capacitance after the inductor and diode.
and let me guess........this certain company that is making these claims wouldnt happen to be the one you keep..ok, this is my bad, I didn't say what the topology was..I am not speaking of led lightbulbs with a boost pfc stage. I am speaking of led lightbulbs with a flyback pfc stage.
As the top post tells, a certain lighting company is making centralised power supplies to run multiple led bulbs, stating that mains transient protection is insufficient when done inside every bulb, that's why theyre centralising it.
A very good point. I never buy anything that's heavily promoted, on principle: if it needs advertising so much then it can't be any good. Any worthwhile product/service gets recommendations from customers/users. I go by recommendation rather than by ads.Marketing is a finely balanced juggling act, go to far and you risk turning people off.
That sums up the obvious feelings of many forum members here.i never want to hear about again!

There will always be a weakest link.All forms of lighting systems fail for countless reasons and so will yours too.
