Hey OP, I'm assuming based on the 600W/150W breakdown, this is a Lutron dimmer, because that's their standard incandescent and LED load limits for most of their LED+ dimmer line. If that's the case, I want to add a tip for you:

Depending on the LED, it's likely the lamps will strobe, shimmer, or simply turn off when you dim down to the low end. This is common with LEDs. If this happens, Lutron has a feature called low-end trim which adjusts how low the lights will dim. This allows you to avoid dimming so low the lights start to have issues. Just look for it on your instruction sheet.

Legrand also has a “Calibration” adjustment on their dimmers for the same reason.

I use that with my dimmers, but what I'd also like is to regrade the scale.

I use the app on my phone and have my lights set to minimum 20% on the low end trim thing, but I only really get dimming between say 50% and 20%, and the low 20%s are nice for night time, low light.

But it's fiddly when the bar has 20-100% on it, and you're only trying to use a tiny section of it.

I wish I could increase the size of each setting from 20-30 relative to the size of 70%-100%. 70% to 100% looks about the same without a light meter so the difference is relatively unimportant.

That's called dead travel in the lighting world. It's a common LED issue.

I use this feature. I generally adjust trim so that the lights come on when I dim up from off. When I do that, it usually is bright enough to not strobe when you dim all the way down from fully lit.

All the dimmable LEDs I have work fine without any flickering at the default lowest brightness setting on Lutron Caseta dimmers. I’ve got a couple of HD store-brand ceiling lights that turn on in a weird way (I assume a capacitor is charging or something) but after a few seconds they’re fine too.

If you're buying big name brand LEDs, you're likely getting good performance. I think the Caseta dimmers are already set for a low end trim out of box to account for typical performance issues. You may want to check your app to see if you can reduce to the trim if your LEDs are performing well and you want more range on the low end.

Oh, good to know! Wouldn’t mind having a couple rooms dim even lower at times.
