Just been thinking, during the UK tour (June) it'll be right in the middle of summer so will it be dark enough for the xylobands to be any use at all?

 

Gig starts at 9pm- still very bright. First Xylobands section around 10pm maybe? Cant see it being dark enough to be honest. Or will it be OK?

I think so, the LED's inside the fabric of the wristbands are VERY bright. I believe you'll still see them flashing, maybe not as bright as in the middle of the night, but still visible enough :)

At first I thought that too, but they've planned to give them at every gig, including in the summer, so I guess they reflected on it. As Thalia said, the bands probably are bright enough.
