I’ve been trying to find incandescent bulbs in the 1800-2200k color range with a decent amount of lumen output. I just keep finding edison-ish bulbs that are in the 100-250 lumen range. Has anyone found anything with a higher lumen output with these specs?
Incandescent light burns somewhere between 2600K and 3200K (generally), so you need a higher power light that you can dim to a lower CCT. Assuming 10-15lm/W, you might be able to get what you want from a dimmed 100 or 150W A19.

This is accurate, but maybe impractical depending on where you live.
@Mai
Very informative! Thank you so much. Unfortunately we were pushing T-24 wattage limits trying to use 60W bases, so 100W+ would be out of the question. But you at least stopped me from chasing my tail trying to find something that doesn’t (and can’t) exist.
@Reese
Title 24 and incandescent are not friends, so unfortunately your options are limited.
These are 2200k and 600 lumens.

Thanks for the link – unfortunately those are LED though. Looking for incandescent only.

Just wondering, why does it have to be incandescent?
To achieve 800 lumen from a 2200K incandescent filament you’re going to need closer to 120W. The efficiency of an incandescent bulbs is proportional to filament temperature.
That means you’d need a 300W bulb dimmed to 120W to get 2200K and ~800 lumen.
You could also run 2x 200W bulbs in series for 2000-2100K and 60W each
You won’t find that unless it’s a very large fixture. That wind will be very loose.
You would be better with a high pressure sodium Edison bulb if the fixture makes sense.

High pressure sodium would work nicely for this. However, should you decide to use one, be aware the you also need a ballast to run it. It can be done in most fixtures that are large enough although you might need to be a bit creative to accommodate the ballast.
@Sloan
Yep fixture needs to make sense. Also the fact that they can get dangerously hot. And rendering with HPS is basically monochromatic. Low pressure sodium or sodium vapor lights even more so. Very narrow wavelengths with all of these types of lights.
@Bliss
Thank you for the suggestions and information! Very helpful. I spent some time searching sodium bulbs and there’s a 35W that just about nails the specs I’m looking for. Are you familiar with any fixtures with ballasts that can be used for an indoor scenario? Or any vendors who might have something like this?
@Reese
Paste the hyperlink so I can tell you what it fits into. And depending on the fixture type it may not be dimmable or only 50% dimmable as HPS and SV lose stability at lower voltages
