Hey all,

Since the demise of the halogen lamp for general use here in the states 3 years ago, I've been using led filament bulbs to try and replicate that feeling of incandescent lamps and chase that high I can no longer get. Problem is, the damn things fail after about a years worth of time. They all tend to go out the same way, slight flickering at first before they fully resort to a failed state wherein they glow dimly and have a 2-3 second period of continuing to glow after being shut off. I've tried 2 different kinds of ecosmart lamps and some 2025 vintage Philips warm glows all failing like this well before their allotted 13-15 year lifespans. Is there any brand that actually lasts or am I out of luck? At least it isn't all integraded led stuff I use.

You could hunt for bulk NOS lamps on ebay. Otherwise I am not sure.

Problem is, the "screw in bulb" is maybe the most LED-hostile format in existence. Rather high intensity on small space, light emission in all directions, means there is not much space where to dissipate the heat. Filament concept works well, but only limited power, like up to 8W for really largeR SIZE bulb. And only when the fixture really allows free cooling air movement around the bulb, so open fixtures only.
With enclosed fixtures the limit is at about 4W, so we are at barely 600lm with the most efficient LEDs on the market (the power figure includes the driver losses), so not that much of light output.

Way better performance you get from purpose built LED lanterns (assume decent design and build quality, so likely not the cheapest trash on the market), but these tend to use propriatery parts, so hard to fix once fails, so you need a completely new lantern.
So more of a "creating a new installation", not a "what to put into existing fixture" thing.
