Anyone know what kind of lightbulb this is?

I have one burnt out and I want to replace them with “smart” variants

Quelqu’un sait quel type d’ampoule il s’agit.

J’en ai une qui a brûlée et je veux les remplacer par des variantes « intelligentes »

While I knew how LED bulbs function, I’d not caught up on the mass manufacturing of them.
