I wouldn't try anything like this until proven. Staring at light doesn't sound harmless to me.

Reminds me of Don't look into laser with remaining eye.

Still, we do it constantly: Any monitor/screen is just a "lightbulb", that we are staring into day to day.

I don't know why you assume you must stare directly into the light source for this to work, compared to for example diffusing the light to a comfortable level with a transparent screen, or pointing a strong light at your bedroom ceiling etc.

Why assume that someone attempting this themselves won't stare directly into the light source. Without specific advise, be cautious of the worse case this might cause.
