Just got mine and it's just as fantastic as the MCE. It's hard to tell but the MCE beam seems a little tighter thus giving more throw. The SST50 has a much smoother beam due to the large single die. Depending on what these put out for lumens they seems very close. Hard to tell which one is brighter. I think MCE will do a little better, due to the lower VF and higher minimum lumens. Either way, hard to tell with the naked eye, they are both excellent. Kudos download.
