Got one of these on holidays recently
Tektite Expedition 300, 7 LED from LeisurePro.com Nice and bright and has a great solid feel to it. Lot brighter than my Photon Torpedo (which I don't have the heart or wallet to upgrade to the LED version).
Used the Tektite on a night dive recently, water was dead clear. Seemingly it's gone to pot now, so will try it again in the murk this weekend.
