The Red EZ arrived mid day. My LD10 was in work duty (shop) so I swapped the red guy into the pocket and used it a few times.
First impressions - Body Color is a deep blood red, the LED tint seems to favor a little more green than my Fenix, but I wouldn't notice it unless I had them side by side.
Both are on Eneloops and after walking around with each on High/Turbo for 5 minutes, the EZ heats up fairly quickly at the head. Makes sense, the head is so small. Up close the EZ has a smaller spot.
One thing I really like right away is the flood on this light. This could be useful for much of the close work I do around machines. I have no way to measure, but output seems very close. I'm sure the great reviewers will dial up the figures soon enough.
Of concern from selfbuilt's samples was the turn to high. I'm happy to report mine is precisely 1/2 turn from low to high. Very Nice. There's a little breathing room after high, but I didn't test how far it might go.
The size is so close to the little LD01, I could easily use it on the keys. I might notice the weigh difference, but not by much.
