Re: Heated Gem
I bought the Eastward on 9-Apr, right after reading BessieBenny's initial review and before the price increase. It arrived at the post office on 26-Apr. I'm in Alabama.
Well, I wanted to love this light. Initial impressions were mostly good--solid construction, well-anodized, well-machined--except that the tail cap is *very* loose and wiggly until it is finally tightened against the body. I compared it with an Aurora WF-600 and liked the fact that it's a good bit smaller overall, both length and head diameter.
I put freshly-charged Ultrafire 18650 cells in each for a few beam shots and a run time comparison. The Eastward beam is smoother and the hot spot is bigger and less intense. That's pretty much as expected since its head is smaller head and has an OP reflector. The reverse clicky is quite stiff, but manageable, and the low beam is significantly lower, which I like.
In the beam shots, the Aurora is on the left and the Eastward is on the right. The wall is about 10 feet away. Sorry for the crummy camera and expecially the poor color balance in the first one. It came out blue, so I tried to remove the color in Photoshop. In real life, I didn't see the colored rings.
Anyway, this is at 1/30 sec. and f/2.8 about 5 minutes after turning them on.
This one is just a couple minutes later at 1/100 sec. and f/2.8.
I put them both head down on the carpet while I tucked in my girls. When I checked them about 30 minutes later, the Eastward was too hot to hold and the Aurora was cool to the touch all over.

Measuring the current with a Fluke 77 gave 0.81-0.82 for the Eastward (my first reading jumped around from 0.73 to 1.03) and 0.41-0.43 for the Aurora. This was 55 minutes in.
Next are two outdoor shots, the Eastward first and then the Aurora. The target was about 50-60 feet away and there was very little ambient light. They looked a
lot brighter in real life. Both shots are at 1/8 sec. and f/2.8 and are about one hour after turning them on.
Here are two indoor beam shots right after the outdoor shots. The first is at 1/30 sec. and f/2.8 and the second is at 1/100 sec. and f/2.8. Again, the Eastward is on the right.
When I checked on them again at 1:40 in, the Eastward was blinking about twice per second. I let them both rest for about a minute, then turned them back on and took this shot at 1/30 sec. and f/2.8. It immediately started blinking again, but I caught it "on." The Eastward was no longer hot.
After resting for 10 minutes, the battery from the Eastward measured 3.1 volts and registered as dead on a ZTS MBT-1 battery tester. I left the Aurora running. A couple weeks ago I got about 4 hours in an less formal test of the Aurora.
I can't find any reason to prefer the Eastward over the Aurora except the smaller size and smoother beam, but those certainly don't outweigh the reduced throw and runtime. Not to mention it getting too hot to hold.

Did I get a defective one?

Here are a couple more shots, both at 1/30 sec and f/2.8. In the first one, the Eastward on the right has a fresh AW 18650 cell, while the Aurora on the left is 2.5 hours on its Ultrafire cell.
This last shot doesn't include the Eastward. I feared for its LED (see current measurements below). The Aurora is 3.25 hours on that cell.
I then measured 0.27-0.28 amps, and after shutting it off, 3.68 V and the battery tester said "dead." My battery tester is too picky, because it was still giving off a bright light. Very useable.
