Gentlemen, I have found, as have many of you, a very interesting family of flashlights. The OMBU 55 is a 5 watt, 2x123 Lithium, 5 inch by 1.1 inch, $120, VERY wide beam (too wide beam) flashlight. The OMBU 33 is a 3 watt, 2 x 123 Lithium, 5 inch by 1.1 inch, $84 Flashlight not so wide beam, that has two light levels (18 and 45 lumens). The Nuwai Q3 is a single 123 Lithium version of the OMBU 33. The Nitestar 3 Watt looks like it may be an OMBU 33 in a different body aand with only the 45 lumen light level. The OMBU 33 looks like a great EDC light. Who has one? Who knows anything more about these lights? Glowbug sells them
