Here is video of some beamshots comparing a P7 light - Magicshine p7 to XML Flashlight
All the flashlights are single cell 18650 flashlights, the magicshine P7 is 1st gen light but very indicative of illumination of models that followed it.. If the MS light is in the 500-600 lumen range, I would say the XML's are in 700-800 range for output. I've only seen one XML that can put out a 1000 lumens but it costs $150.00
Video 2 is XML and MS P7 in High & medium modes only: http://www.youtube.com/watch?v=t5A0Z...el_video_title
If you have any questions please leave message.. The XML's on high mode give about 45 minutes with medium mode kicking for another 30 minutes of useable light.. The medium mode is right on par with the MS light output but light is more directed and not as floody. In medium mode you get 90-110 minutes depending on what cells you are using. I am using Ultrafire 3000mah and Japanese UF 2600 mah cells..
