flashlight on shabbat

I have heard that R Abadi maintains that one may carry a flashlight on shabbat (in the eruv), but I can’t seem to find this in psak Ohr Yitzchak. Is this his positikn? Can you help me find the correct siman?

You’re not going to find it in the Ohr Yitzchak because he never said it.

An aside, do you know of any Eruv the Rav approved of? I can count them on one hand.
