I really think the very best bang for the buck is the 1000 lmn Orcatorch D550 sold by board member Dano at Mako...... These are genuine Orcatorch D550's with the Mako badging added. You can check Ebay or Amazon but don't think you'll find a better price than the $70 that Dano charges......and if anything ever needs attention you'll be dealing with Mako... I have two of these lights. One as a simple back-up and tropical travel light and another that's mounted on my Ling Cod carbine. The ONLY difference between the Mako and the D550 is that the Mako light has the Mako badging on it.. Comes complete with battery (18650) charger and case...
