First, I want to say thanks to the community behind the BFL LT1 for creating such a fantastic lantern and writing a comprehensive and detailed manual.

I wanted to contribute a “Simplified Visual Quick Reference Guide” which concentrates on just the features I use most.

I often found with so much detail in the manual it was difficult to find how to use the basic features.

I would appreciate any feedback on the quick reference guide and any things which are incorrect or not clear.

Quick Reference Guide Features

  1. it obvious whether the clicking function works from the ON or the OFF position
  2. I use a little different nomenclature to describe the clicking and holding actions
  3. it is optimize to display on mobile phones
  4. I am releasing this under a Creative Commons sharing license

Future Enhancements

  1. I will make a special size PDF version that can be printed and that can be rolled up and stored inside the battery storage tube.
  2. this will be a public online Google Document so you can easily customize or translated it (a Gmail account is required)

I hope some may find this useful, it was fun to author this quick reference guide.

I usually cut'n'paste from PDF files to put torch instructions in my iPhone Contacts (under a category of "Information"), so this is a great resource. Thank you for your efforts! PS: Just got the LT1 and wish there was something between low and high on the Switch LED indicator - low is too low and high is too high. However, that's the only 'fault' I can find with the LT1... LOL

The small one, folded twice horizontally and once vertically, fits inside the bottom cap. Since I already have a set of instructions stashed in my Q8 tailcap this way, I figure that’s where I will remember to look.

Thanks Mr. McCormack for your very useful posting. I have printed this for my quick reference.

One question: How is the “new” version of the LT1 lantern? I have the original version in Orange. It was sent to me by mistake. After I complained, Sofirn (in China) assured me that I would learn to like the bright Orange lantern. Now I agree.

But I still want a Green lantern. The “new” version in Green seems to be selling well and now in short supply.
