If you are contemplating the sizes of the X0 and the X03, you might want to take a real close look at the T series by Inova. I will expand on what Matt has posted. The T3 throws a real bright white beam for a long distance. It has been said many times that the Inova X and T series are the "throw kings". The excellent checkered body and tailcap provides a superior grip, with or without gloves, better than the octagonal smooth finish of the X0 series. Both the momentary and constant click on cap switch (not found on the X0 series) is sure and strong. Not flimsy or indistiguishable as are on some other high end lights. Although the beam has excelllent throw, its spill is minimal. The solution is to simply press fit onto the front a Surfire flip top cap light filter made for their P and G series models. This unit will fit onto the T3 model without problem. And will smooth and even out the beam for good wide area coverage. If you require a long throw and a tighter beam, just thumb flip the hinged cap. That' s it. The hinged cap will help minimze any rolling. Very versatile package without breaking your bank book. This is the current setup that I have as my non emergency utility light.
