Fenix E20 High Performance Adjustable Cree LED Flashlight

The Fenix E20's design is focused on accessibility and convenience. It uses two versatile AA batteries and maintains balance between high output and long runtime. It is firm, waterproof, and lightweight. In a word, Fenix's E20 is an outdoor flashlight with a rare combination of high performance, high quality, and low cost.

Pros -

1) Impressively bright. If your eyes have adjusted to the darkness, this product can momentarily blind you if you shine its light on objects within a foot. If you bring the light close to your lips or cheek and turn it on, you can even feel the heat from the light!
2) Supposed to be waterproof
3) Reasonably well made. The quality of construction is not at the level of a coast 1AA flashlight that I own but good enough. The batteries do not rattle. This flashlight cost only a few dollar more than the Coast, but delivers about 10 times more light.
4) The light is very white. No blue/green/yellow tinge here.
5) The light cover is glass - this is great. Does not scratch easily. Plus it has an antireflective coating to enhance light delivery. It sometimes makes you think that the protective glass is missing and you are looking the reflector and LED directly with nothing in between.
6) 2AA battery usage is just great. Easy to use existing rechargeables.
7) Its slim but slightly long profile means its easy to carry and not lose.
8) Anodization seems to be pretty well done (hard anodized).

Cons -
1) Black color - should be any color (like red, blue, silver) other than black. Black is difficult to spot in a collection of items. I need my flashlight to "pop" out at me.
2) A tad expensive - but then the CREE led's aren't cheap either.
3) Defocussing the bead will lose light (in addition to spreading it around). The LED moves below the reflector and not all of the light is captured and delivered when this happens.
4) The on-off switch is at the back and positioned such that the light cannot be placed vertically.
5) The light rolls very easily. All contact surfaces are round.
6) Does not use the latest and higher efficiency CREE led currently available.
7) No evidence of gold plating on +ve contact inside the flashlight. Don't know how the product will fare in the long run. Expected better quality in this area considering the price paid.
