Which scope mounted lamp?

[Bowlander]

I currently use a 6v clulite for my nocturnal wanderings with the air rifle but am looking at upgrading to one of the new fangled led torches that clip on the scope. The battery pack on the clulite is quite awkward, especially when climbing stone walls etc. I've been trying an alpkit gamma held freehand by the forend and have shot rabbits out to 40yds but would like something a bit more purpose built. Any suggestions much appreciated? Budget is

I have one up for trade, mate. It operates with a remote switch so that you conserve battery power. It works out to 100m. Happy to trade with you.

I appreciate that isn't a comparison - just an offer.
