Nice teardown and review!
So I have a question..
So what good does the fusible link do for the consumer? So maybe there's a power surge for whatever reason. Blamo, the fusible link blows. What good is the fusible link? The light's still dead, the consumer can't replace it. It still has to get sent back to the factory for fix/replacement.
I'd rather have the link blow, than burn my house down. I once saw a CFL start smoking, then puffing, and it wasn't blowing the house breaker...
