I found myself in a similar situation. I'm not suggesting this is what's happening to you, but in case it helps: my mistake was that the light and sound were increasing too quickly and my body was turning away from the light and shutting off the alarm before I had became conscious.

The approach that worked for me was:

- Increasing light from warm dim (~100 lumens) to bright white (1000+ lumens) over the course of ~30m. Even though you're not conscious and your eyelids are closed your eyes are still responding to the light and rebooting your circadian rhythm.

- A few minutes after the light reaches the brightest setting, have a sound-based alarm. I have nature sounds that start quiet and get progressively louder over about ten minutes, but I usually wake up after less than a minute.

- Getting into bed at a consistent time (+/-20m) seven and a half hours before the sound-based alarm. This is the hardest part since I rarely feel tired that early (yes, even when I've exercised) and it feels like a waste of time to lie in bed and stare at the ceiling. But I know from regular experience that when I wait until I'm tired to get in bed I have an unproductive morning.

I have a Hue light on my bedside table that goes from 0 to max over 30min, plus three bulbs in the ceiling socket that do the same, but are staggered. Like bedside can be 6:55-7:25, with overhead 1 from 7-7:30, overhead 2 from 7:05-7:35, etc. So you have the four lights brightening together over the course of 45min or whatever longer period you want.

If it's gradual enough, you won't just bury your head, and if it's enough bulbs, it'll get bright enough to convince your body it's daytime.

There's another trick I've been meaning to do. The Hue app's wake up routine turns it on to a low temperature light, but turning it a little higher temp/bluer once I'm up does help trick me into daytime. I'm meaning to make a cron job on my raspberry pi to make my own wakeup routine that is a little slower to avoid the need to stagger lights, and also increase temperature once it's bright. If you know linux, the pi is easy.

Even without the fancy pi stuff, it's Good Enough. The Hue bulbs add up fast in cost, but it's worth it to me. I have the white ambiance ones.

It's not bright enough.

- Sunlight - 10,000 to 120,000 lux

- Light Therapy lamp (from 4 inches away) - 10,000 lux

- 60W Philips Hue light bulb (800 lumens, 120deg beam angle, 4in away) - ~25,000 lux

- 60W bulb (same specs, but 5ft away) - ~100lux

Those numbers for the 60W light bulb are also optimistic, and will go down if you put it in a light fixture that doesn't redirect all of the light into a 120deg beam (like a regular standing lamp).

So, either place it ~4"+ from your face, get multiple, or find a brighter 100W+ smart bulb.

Additional anecdata - I've used the Philips sunrise alarm clock before (apparently 300lux), and it tends not to wake me up either.

In other news, if anyone has a 100W+ white color temp changing smart bulb to recommend, I'm all ears.
