I have a Moon Meteor 200. It's a brilliant little light (in both senses) but the charge indicator is pretty useless. Burn time on 'overdrive' is supposed to be 1 hr 50 mins, and I have timed it (off the bike) at 1 hr 45, so not too far off. But if I set off with it fully charged and the blue "over 60%" light on, it changes to the green "20-60%" light within a couple of miles, and to the red "under 20%" light after about 30 minutes. It hasn't run out on me yet (my commute is about 55 minutes) but it makes me a bit nervous. I bought the Meteor 250 as a reserve light, and because soon the cold will mean the battery life is reduced anyway (Moon reckon the burn time could be down to 50% at freezing point). I don't fancy being left without a light on the dark lanes I ride on. But my guess is that the charge light is just plain unreliable. In every other way it is a superb little light, and even in the pitch dark I can get away with the middle brightness setting if I don't go too fast, which is supposed to last up to 3½ hours. Perhaps give the light a proper test at home before assuming it won't last the distance.
