The 'almost immediate' (or similar) wording is probably dishonest. I have used the lamp daily for several weeks now and I have not noticed any changes as the manufacturer claims. Maybe over a more extended period of time improvements may become evident.

### ⭐⭐⭐⭐⭐ Fight the good fight
*by G***T on 5 January 2026*

I don't find the flickering light annoying. I'm not sure if it works yet. We'll see, but even if this light bulb lasts one week, I'm glad I bought it. I think there's a huge brain epidemic going on and doctors are just guessing and giving it fancy names (in my opinion, allegedly).
