Good:
Nice even spread of light, wide, nice colour, lasts at least as long as they say, solid housing.
The medium setting is enough to see by on simple stuff and road. The Max is plenty going down. Only a bit of difference Max->Boost.
Bad:
Battery had to go back because it had a loose connection, but they returned it super quick. Typical for Hope: minor quality problems but really good returns service. Know of 1 other with same problem.
I don't trust the battery strap so I use an extra strip of velcro.
I've only had a quick look at a trout. Those seem a tad brighter with a beam spread thats more letter box shaped (not surprising comparing the layouts). The light is whiter than the Hopes.
I've also seen the seca, lumi, aye ups, and the exposure 3 led one. There all good and in terms of light quality/quantity there is not much between them, although the aye ups are at the bottom IMO.
None have a beam that penetrates as much as 10W HID. The best I've seen to date was a 20W HID. But the problem with them are reliability and non-adjustment.
