alt Hacker NewsJust a fun random fact from me: We do need more lumens. Not for normal (non-production) indoor lighting in most situations, however, I always want a bright light for my outside lights, and I find that most 100w-equivalent (1500 lumens) are just not quite enough. 2,000 lumens is almost there, however, 2,500 lumens would be beneficial. Both 2,000 and 2,500 lumen bulbs either don't last in temperature extremes, or are super expensive. The power on time (think hours per day of use) and color of the light matters as well. In my use case, I need a bulb that can withstand long periods of time being run from dusk till dawn. I am willing to pay a decent amount for a guaranteed warranty for X years, however most bulbs of ANY amount of lumens only guarantee 1-3 hours a day for 1-5 years. When you need 7-10 hours a day, well...

Try looking into videography COBs. I would recommend something like the Zhiyun Molus G300, SmallRig RC 220B or similar.
The absolute cheapest lumens per dollar COB would be the GVM SD300D, although I highly question the reliability and light quality.
Have you seen the Philips TrueForce Core 40W LED bulbs? Not sure if they're sold in the US, but they're 4000 lumens, "last up to 15,000 hours" (whatever you make of that phrasing). They're quite huge but fit into a normal light socket. Not very expensive either.
I have a pair of PAR38 LED bulbs from Cree Lighting (2100 lumens) that are rated for 25,000 hours. They're in a flood-light mounted under the eaves of my house.
I never got around to putting them on a dusk-to-dawn timer, so they've been burning 24/7 since I purchased them at the end of 2020 (except for the occasional power outage, of course). I paid $20/each for them.
Sample size of 1 (technically 2), but there are definitely products on the market that meet your criteria.
Relinking what I've already linked in a sibling comment, but I've just started having these die after 4 years of continuous use ~12hrs/day: amazon.com/dp/B07BRKT56T
Interestingly, 4 of the 6 that I had running all died in the same ~3mo period, but still I was pretty happy for 4 years of use for $25/ea.
I throw 200w led onto my garden. Enough to see where you are but a long way from daylight.
You can derate/"underclock" a regular LED and it will run significantly cooler, heat being one of the big drivers of LED lifespan. Downsides are less output per lamp (so need more lamps, probably why long-life lamps are expensive on a per-lumen basis) and you need to do a bit of DIY.
