Mike at OpticsHQ was nice enough to send me two E series heads for evaluation.
The E series heads that OpticsHQ sells are directly compatible with anything that has the SureFire E series body threads. This includes the Aleph 1x123 bodies, the Vital Gear Bodies, and (of course!) the SureFire E1 and E2 series bodies.
Shown below - E2e with OpticsHQ head, E1L with OpticsHQ head, E1e with incan head, and TW4 clone with VG 1x123 and KL4 head.
The head is just a tad larger in size to the current SureFire KX1/KX2 heads - it's about 1mm longer in height.
The reflector head, however, is quite a bit larger.
The head itself (surprisingly) can be taken apart - the pill can be removed from the head just by grabbing the spring and unscrewing it.
The solder contacts (shown above) is what actually hits the body to make contact. Ironically, on the E1 head, the contacts were built up, and still didn't make contact with the body - so unscrewing the pill 1/4 turn was enough to make contact with the body so that the light would work.
The light - well, the light is clean, pure, and whiter than my SSC headed Novatac.
The heads are deeper than most - so you get far less spill that I would have thought. Comparison pics below. In order, Novatac 120P, OpticsHQ E1, and OpticsHQ E2
One minor niggle and one major niggle of these two heads.
Minor niggle - the heads are SHARP - be careful on the body side threads.
Major niggle - the pills really should be tied down better. I worry about their use in this case.
The long term testing begins - the E1 head starts becoming my EDC unit paired with a VG 1x123 head tonight.
Night shots as I can get them.

Also, we did not try to design the best throw, but the best compromise between throw and spill (and I think we succeeded
