Im looking for a bright low budget mc-e or p7. I have a mg PLI that is an mc-e but I was reading that that light only makes about 300 lumens OTF. Do any of these DX or KD lights really put out the advertised 700-900 lumens? How about 500? Also the mg runs off of 2 123s, Will a single 18650 light be brighter? I am trying to keep the price around 50 bucks so any suggestions would be appreciated.
