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.
