One little warning though there seem to be several versions of this light Ultrafire / Uniquefire/ Yezl ... I thought they were all the same but apparently there can be difference in threads/modes/bezels (mine is actually a Uniquefire 3 mode from DD). BLFer Buwuwe made a little review in German ... Here is the crude translation... brted also reviewed it, Manafonts has a different bezel and apparently the 3 mode can be converted into a 5 mode.
