Night Shift not dim enough?
There's a reason it doesn't help: Night Shift changes color, not brightness. It warms the screen — it never lowers how much light it puts out. Here's what actually makes your Mac darker at night.

Warmer isn't darker
Night Shift was built for one job: reducing blue light in the evening by warming the display's colors. That can help you wind down — but it does nothing to the actual brightness. A screen at its lowest setting emits the same amount of light whether Night Shift is on or off; it just looks more orange.
So if your complaint is “the screen is too bright at night,” Night Shift was never going to solve it. The real problem is that macOS stops the brightness slider at a fixed floor — and in a dark room, that floor is genuinely bright.
The real fix: warm and dark
Keep Night Shift on for the warmth if you like it — then add real dimming underneath. Turn brightness to its minimum, and use LUMEL's Eclipse modeto go up to 70% below that floor. You end up with a screen that's both warm and actually dark — the combination Night Shift alone can never give you. It works on any Mac, including the MacBook Air.

Night Shift, answered
Does Night Shift reduce screen brightness?
No. Night Shift shifts the display's color temperature toward warmer, amber tones on a schedule. The luminance — how much light the screen emits — stays exactly the same. That's why a screen with Night Shift on can still feel too bright in a dark room.
Why does my screen still feel bright with Night Shift on?
Because warmer isn't dimmer. Warm light is gentler and easier on the eyes at night, but if the underlying brightness is still above what a dark room needs, a color change can't fix it. You need to actually lower the light output — and macOS stops the slider at a fixed minimum.
How do I make my Mac dimmer at night than Night Shift allows?
Turn brightness to its minimum, keep Night Shift on for warmth if you like it, then add a dimming layer for the rest. LUMEL's Eclipse mode dims up to 70% below the macOS minimum — so you get warm and genuinely dark, together.
Night Shift vs True Tone vs f.lux — what's the difference?
All three adjust color, not brightness. Night Shift warms on a schedule; True Tone matches the room's color; f.lux does a more aggressive version of Night Shift. None of them lower luminance. For that you need brightness control or a dimming layer.
Actually dark, not just warm.
LUMEL's Eclipse mode dims below the macOS minimum, so your screen can finally match a dark room. Free, no usage limits, no account.
