Surefire E-Series Compatible Heads?

So it seems that in addition to Malkoff, Aleph, Valiant Systems, Fivemega, and Solarforce, there are other light engines/heads that work with the Surefire E-Series body tube thread pitch.

Is there a comprehensive list somewhere? I did a search, but my search-fu may not have been up to the task. Was unclear whether Nitecore's Extreme heads would work.

Thanks in advance.

You can double check, but I believe the McGimzo mules/haiku heads work with e series tubes.

Most Tain gear is E series compatible at one end or the other.

Yes, and parts from Vital Gear, and Leef, and cubebike, and balrog, and 1WRX7, and DSpeck, and Tana, and RPM, and kuku427 (Veleno Designs), and Lumens Factory, and TLS, and ganp, and TranquillityBase, and Mirage_Man, and ...

There are also a lot of E-series milky mods, although he hasn't been too active recently.

If you get creative with spacers and adapters, the "lego" parts universe can be expanded further ... to Sunwayman, to P60 / C-series (ronac/Cryos, Moddoo, others), etc, etc.
