- Ok all, here is the video explaining how i refined a lantern head for the LT1 Mini and still use the original IF25 LED up-firing configuration, with the original quad-TIR optic still used. I will get the drawing of how it was done completed soon, explaining its principle and how the Mini V1 prototype works. Here i have modified the LT1 Mini with the same LH351 2700K and 5000K 3535 LEDs as used in the full size LT1 lantern. As planned for the production version, it will have the same LT1-Andruil operating firmware as the fullsize LT1, some body design changes, side switch changes, base cap changes to add a removable magnet, (the magnet will help hold a wider accessory base plate for more stability) and add a 18650 sleeve so it can be used with a single 21700 or 18650 cell.
sorry i must have missed the messages. I have tried many different types of center diffusers & shapes of it, top reflectors, (white, opaque, mirror, satin, etc) and same goes for the lens/globe designs. If i knew it would not drive inital MSRP cost up, I would still go with the down-firing design of the full size LT1, as that has tested superior than any other design I worked or or seen on any lantern or shade shoved over a flashlight. The goal of a lantern is to produce light, as evenly as possible, 360 degrees in all directions, as smoothly as possible, with as little eye-glare as possible, with the minimum hard-lighting & artifacts as possible, with as little angular-tint-shift as possible from different angles, etc. I have yet to find any factory consumer LED lantern that can do that, and the same goes for older incandescent lanterns.
as the initial cost of the host IF25 from Sofirn runs between 34 to 39 USD, by utilizing its current up-firing design the best, most light-efficient, smoothest way possible to achieve as close to that the BLF LT1 does was my goal, and to keep their manufacturing cost as close to the IF25 base regular price as possible.
I understand people will have different opinions, different design ideas, and different thoughts on it, and many have helped me with tips and ideas to work on something that works, without making it over-complicated to drive up cost. a team worked on the BLF LT1, with members like Toykeeper, Lexel working to perfect hardware & software, and other team members bringing in suggestions and ideas, as well as helping with the logistics, (interest list keeping by SigShooter, logo design refinement by amishBill, and other support from SBslider, Barry of Sofirn, etc. it was a monumental task to get the LT1 to the market as a reality.
We will be drafting up a basic cross section of the Mini and how it works as tested in the prototype soon.
I do appreciate your tips and pointers, and be rest assured most of them have been tested and still under some testing & refinement to get it to work.
