I’m not sure either. Not sure if this helps, but I have been using Ecosmart lamps as of late, though they are just regular ones, most being 2700K, one 3000K, and two 5000K.
I have a 2700K snowcone from 2020 that is has just about five years of use in a table lamp, used about three hours a day, but after that generation they made them even lighter, which I don’t like. They still had weight then that gave somewhat of an assurance on how quality would be but now they feel light as a feather unfortunately. I have two other snowcones in use, a 2700K in a closet light (installed in 2023 I think), and 5000K in a garage light (installed in 2022 I think) and those have been working good.
Their filament lamps have been good to me as well. I know you said you tried them but I’m not sure if you tried the ones I used (regular ones). I have some 2700K 60w (closet light) and 100w equivs (floor lamp) installed in December of 2023 and they have been going strong no issues. Along with a 100w equiv 3000K (installed in mid 2023 I believe, room light) and a pair of 5000K versions (outside lights that are D2D, Oct 2023 and Aug 2025). The October 2023 one is a notable one as before that, I was installing Feit filament LEDs and literally the longest I got one of those in those outside lights was a year and a half, no joke, and started getting those in 2018 (dumb I know).
As
@HomeBrewLamps says, sourcing older LED lamps might be your way to go. I have 2700K 65w equiv GE BR30s and Feit BR30s from 2018 (kitchen), another from 2021 (kitchen sink), and Feit G25 40w and Great Value 40w equiv (2018, most of the GVs had failed over the years except two, bathroom), and the best ones, a pair of Feit Electric 85w equiv BR30s in 5000K, that have run D2D since January 2019 with no issues. I haven’t had failures from the lamps mentioned above except for the GVs. The only mass failures I had were with the Feit A19 60w and 100w equiv filament LEDs. The longest I got from one of those was I think three years, in a garage opener light out of all places. People trash on Feit but I have great experiences with some of their older LED lamps.
Home Depot is closer to where I live so that’s been where I’ve been getting my LED lamps lol. Can’t say anything about the other brands.
