Other Host Standards

Please forgive my newbishness or my inability to find what I need by searching, but can anyone list the more common standard flashlight hosts, such as P60, along with the specs and dimensions? It's easy to see from reading that P60 is the king of the flashlight hosts, but what other hosts are out there? I would like to build a flashlight or three, but I don't want to box myself into a corner by choosing something that would require a lot of custom fabrication in order to use other modules. I plan on picking up a P60 host, but I would also like to get something a little larger to fool around with that would give me some longer run times and better heatsinking for some of the big-gun LED projects, like multiple XM-L's or SST-90's. I have found a few hosts that use multiple 26650's, but I do not see anything indicating that host will accept other common interchangeable components as the P60's do. I also see terms such as D26, D36, D52, etc., but I do not know if that a term for a common host standard or if it simply refers to the inner diameter of the reflector? Some of the hosts that I am considering:

Try this link for a very good list of P60 hosts for starters (thanks orbital!) It doesn't give dimensions but it may give you a launching point to explore.

My favorite thing about standards is that everyone has their own. :shakehead

I appreciate the reply, but perhaps, I didn't phrase my question very well. I have found a wealth of information about P60 lights on http://flashlight-wiki.com/Main_Page. BTW, I didn't know about the site when I posted my question. I now believe I was asking about something that doesn't exist. I was thinking that there may be another flashlight standard, such as P60, that is more suitable for building flashlights with higher energy/heat-sinking requirements. It's been difficult wading through a see of terms and acronyms to discover which part(s) of the flashlight does the standard refer to. It's the male, pounding-on-the-chest while grunting part of me that thinks, "Why not go bigger?" I now realize that there are some limitations and dangers due to existing battery technology and the efficiency of the latest and greatest LED's. I will wait for technology to catch up or I will become more creative in my endeavors. I was thinking about building something about the size of a 4D Maglite with maybe 5 SST-90's and as many large batteries as I can pack into it. When I point it into the sky, I want the people in my neighborhood to wonder if there is a carnival nearby. I'll push onward; learning is most of the fun anyway.
