Three 240-lumen LEDs, and encased in Hope’s trademark CNC-machined aluminium.

It will come as standard with no battery pack, but you can use standard li-on batteries or the company’s own two-LED battery to power it.
Price will be around £100.

Thoughts?

Mine are that it's nice but still seems expensive, and I'm assuming those figures are inflated (or are a max but unachieveable output), as per the Hope LED 4's 960 lumens or Magicshines 900 lumens. So why not produce something with better LED's?
Also the mount looks nice but is it QR?

I'm wondering which kind of LEDs would be in here. I cannot imagine the real output would be 720 lumen because if so it would be a pretty good deal and Hope is not renowned for being cheap.

http://www.brightbikelights.com seem good. Good reviews for foot and bike orienteering, haven't seen the product in the flesh though…
