Hi Vicky, thanks for another giveaway!
Lately I've been really liking the oBulbs especially during power outages. I was under my desk last night working inside my computer, I was able to attach an oBulb to the bottom side of my desk to see what I was doing.
But really I don't think I can say a single oLight is my favourite, I have several different types ranging from an i1r2 to a Freyr to a PL Valkyrie, they all provide illumination but I have different use cases for each of them.
