| Here's the beam shot line up. The Marwi P7 is a halogen conversion - More info here on this light The DX1 P7 is flashlight conversion with the 1.4 amp/2.8 amp/Clicky switch mod - More info here on this light The Hoffman P7 is a one-off home brew of mine that was too expensive to have made in a machine shop The DX2 P7 is Deal extreme SKU 25149 P7 bike light. - More info here on this light I had not taken actual current measurements on this light yet, so I didn't know the actual current settings for High and Low The 1.4 amp/2.8 amp/Clicky switch mod is explained on this page |

| This is my favorite beam shape, the Marwi conversion It lights up the trail just in front of your tire and then throws out a nice fat bright spot down the trail 25+ feet or so. This gives a nice full range of light when on the trail. |
Just for fun I clicked on all four P7's lights as a last shot. The leaves started smoking so I shut er down. :) |
