Ah yes conspiracy theory, or not, the dreaded 'designed obsolescence'! Just look to all that care taken in the circuitry only to be squandered with the implementation of the filaments. Many decades ago I was on an undergraduate engineering exchange at Philips gloeilamp fabrieken Eindhoven my project was to research accelerated stress testing of H4 bulbs to replace the mass quarantine of bulbs for months required to weed out the failed that had degassed. The aim was to incorporate the testing into the production line no mean feat as they spilled off the line as fast as a machine gun sprays bullets.
Thank you Chris for walking where I fear to tread. I thought these LED filament bulbs were going to be my saviour from the horrible buzzy Compact Fluorescent UV emitting horrors that never seemed to last or light as promised. I'm sure my old incandescent lasted longer. So embraced LED filament, for their immediate quality lighting for my ageing eyes, even at the cost I mean they're LED bound to last right. But no I've got one now who happily periodically flicks off and on, initially thought I hadn't engaged the bayonet properly because didn't feel fully engaged when swapping with a known good from another room. But definitely failing. Didn't have much joy from the conventional LED units either with early failures from OSRAM and LAP should have sent them back as died early. Now where did I put my Carbide?
What’s really frustrating is that LED bulbs could be made to last for years and years. But they end up overdriving the LEDs which eventually kills them, or skimping on components which then fail. To be fair to Philips - the components in this one do seem properly specced - high temperature capacitors etc… But there’s obviously a design flaw somewhere with the filaments.
