I really like the Exposure lights. I have an old Maxx D (mk2, I think) have been very happy with it. My only complaint is that it’s so bright the joystick I used with it doesn’t make much of an impression! I took care of that, though – lost my joystick, which is a bummer but did give me a good excuse for a new purchase…
I just received a 2012 Diablo mk3 in the post. Very impressed! Similar brightness to the mk2 Maxx D on full but not as wide a beam. Comparing it side by side with a joystick in the back garden last night was interesting: Although the diablo only lasts 1 hour on full power, even on medium (3 hour burn time) it’s still quite a bit brighter than the joystick on full (also 3 hours). In fact, the diablo on low is not *that* much dimmer than the joytick on full. The beam is also slighly more yellow than the joystick, which I find a bit nicer on the eyes. The joystick I was using to compare is around 2 years old though, so the new ones are probably slightly brighter.
I still think Joysticks are great lights but if you are considering one, it may be worth paying a bit extra to get the diablo depending on what you want from it.
