I have an E1e that is dieing for a warm white cree upgrade, I was thinking a simple sandwiche shoppe driver board, a RCR123 cell, the TnC head with a MCr reflector would go nicely. Anyone know more about this than I do? I am very new to TnC products.
I'm not sure why would you want a Sandwiche Shoppe driver. We custom build TnC canisters to just about any spec and have much more variety of prebuilt canisters, all at a lower cost than the Shoppe. In addition our cansiters are the most versatile out there with even more uses on the drawing board. Our canisters fit in Key-Lux AA lights which are smaller than any E Series light all the way up to multi C cell tubes with every battery configuration in between. In addition our canisters *DO* work on Surefire heads, Aleph heads, VIP heads, MR Bulk heads and others.
Perhaps I should be posting our agenda for building parts?
We are changing the name from TnC SF-Series to EDC-Flex Series. Chris never intended SF to mean Surefire, that was an oversight and it has caused some confusion. In this post then I'll call the SF-Series EDC-Flex.
In January I expect to begin selling E Series adaptors to fit our TnC EDC-Flex tubes for using E Series electronics. We already have an adaptor (Power Pack) to fit E Series heads using TnC Canisters.
We will then build E Series adaptors to fit E Series tubes onto TnC EDC-Flex heads. After that we will build C Series adaptors to work on EDC-Flex tubes. Then we will build extenders for our tubes so you can run 2x or 3x AA, 2x or 3x 18650 cells, etc. There are a number of other parts in the queue as well I won't post since ideas are being copied quite rapidly at this point on CPF.
We've made things very complicated for ourselves and for flashlight enthusiasts trying to build unique and modular parts. It seems we have created much confusion and extra work.

We wish to continue doing this, however in addition I'm going to be posting TK lights for sale as well for those who don't want to wade through all the options. Believe me, it would be much easier to just pop out E Series parts. There are limitations to the E Series we have tried to overcome with our EDC-Flex Series.
