Hey Jase I got mine last night and soon as it was dark went with a mate to some bush to check em out. BLOODY FANTASTIC is all i can say, they throw a beam well past a 100m we even picked up some possum eyes out at about 250-300. I thought i noticed a bit of fade after an hour but it could of been the reflection of the city lights in the cloud cover as the night seemed to get brighter.
The only downside is the three mode thing, pi55ed me off having to always tap through to high.
You were right too Fen high beam seemed to spook the rabbits a bit we could lot closer on low, the strobe appeared to dazzle a few as well.
