I have a bunch of all, and here's my impression. First, they're probably all overdriven Q5 emitters. Second, the DX and KD are probably the exact same module. Third, the tint on the DX and KD is cooler while the Solarforce is warmer. Fourth, the DX and KD have better regulation and are brighter @ 8.4V. The Solarforce is about as bright at 12.6V. Fifth, the Solarforce is about $25 on eBay while the DX and KD modules are about $15. The KD was recently priced at only $12.59 and was a steal. It is still the cheapest of the three. If you are interested in a well-regulated multi-mode module, don't overlook the 0-100% "3-mode" (actually 15 mode in 6 groups) Q5 module on DX. Mev at LightReviews measured it to be slightly brighter than a Fenix T1 with very good runtimes.

Just letting you know.. My new SolarForce R2 module fried when driven by three AW rcr123a's. It was supposed to handle 18v. I feel just a bit frustrated. You may have better service with the DX/KD variety.
My3KidsDad: Didn't you report in another thread that you were using 3XRCR123A with the 5-mode Solarforce? The 5-mode Q5 and R2 modules are only rated to 8.4V while the one-mode modules are rated to 12.6V. I followed your post with a warning that you could fry your 5-mode module at this voltage and included the voltage limits reported on the Solarforce website. Everybody needs to be aware that individual modules may have limits of 4.2V, 8.4V, 12.8V or 18V. I wish that all manufacturers put the voltage limits and other specs right on the module like DereeLight and MTE.
