5.0 out of 5 stars Great All-Purpose Light October 11, 2010

By Gregory Clark

Color Name:Black|Amazon Verified Purchase

I got this light as a backup for my headlamp and wanted a durable, bright LED that took AA batteries so I can run all three lights I take with me on the same AA NiMh rechargeables and don't need different sets of batteries for each. I took this light on a caving trip last weekend and was impressed with the throw and also the durability of this light. I got about 6 hours of use on a set of 2100mah batteries in constant 45 degree temps, mostly using the lower lumen setting but freqeuntly using the 150 lumen setting for brief periods to look for routes or view high cave ceilings or distant features. I know there are brighter lights available and there are lights with more specific features, but this light is well made (dropped on rock w/o any damage other than a nick in the aluminum bezel. ran at good intensity util it was time to change batteries then still provided good light but would not switch to the high setting until I changed batteries. the lower lumen setting was still brighter than my black diamond halogen headlamp and at high, has more light with a better throw than my 3D cell Maglite. the reflector on the Fenix is much better that the Mag so the light is also more usable with a good combination of bright center beam with a fair amount of general flood around it with no irritating rings or shadow in the beam. This light is not focusable, which would be a nice feature, but that is available in other models and at this price point the E21 is an outstanding light.

5.0 out of 5 stars A solid performer March 4, 2011

This isn't your cheaply Made in China junk; it's high-quality Made in China junk.

Seriously though, the machining and finish are top notch, and is what I expected. The only thing that has me curious though is the high/low setting. The manual sez high is 150 lumens and low is 48 lumens.

However, you can hardly tell the change in intensity from the two positions. Either the light is super-efficient at low power, or low power is much more than 48 lumens.

I like that it is IP-x8 (IEC Standard 60529; Ingress Protection; adopted by ANSI-60529). The first digit "x" in the IP rating is the protection against foreign objects such as dust, and x = "not specified", or "don't care". The second digit '8' is the highest waterproof rating and means "Waterproof when immersed beyond 1m".

For those of you that are not familiar with them, the IP waterproof ratings are as follows:

0 = No Protection
1 = dripping water
2 = dripping water tilted up to 15 deg.
3 = spraying water (water spray tilted up to 60 deg).
4 = splashing water
5 = water jets
6 = power water jets
7 = immersion in water up to 1m
8 = immersion in water beyond 1m

If you want detailed information as to what those descriptions mean, google IEC 60529.

5.0 out of 5 stars Great Light November 3, 2010

By Michael J. Brent

Color Name:Black

Just got one of these.
At low power (48 lumens) its alot brighter and has a better throw than a 2nd generation 2AA LED Maglite, which is rated at 69 lumens. Go figure.
At high power (150 lumens), its like a car headlight. No kidding. Its stupid bright.
Its not focusable but its set for a perfect balance of spotlight
and flood. I can stand in the street in front of my house after dark and light up the stop sign 3 blocks away.
I was just up in the mountains and in the pitch dark forest
it can light up the woods like a search light.
Very solid and well made. Has a heft to it.
I know Fenix makes some more exotic lights that run on 2AA's
but how many people need a light with 6 different levels of brightness?
It seems to me this is all the light most people would ever need.
A steal at $35.00

3.0 out of 5 stars A very good light at a good price. September 22, 2011

By J. Davis

This is the first quality made LED flashlight I ever purchased. I bought this light a few weeks back and I have went on to do a lot more research and acquired a couple more flashlights. I have revised my review accordingly:

The Fenix E21 is a very well made flashlight that offers a lot of light for around $30 bucks. It has a convenient form factor, which uses readily available 2 AA batteries. The beam has a decent amount of throw and a reasonable amount of spill for flood lighting. You get two modes activated by a simple twist switch, but no strobe or SOS. Contrary to what some reviews have said there is a noticeable difference between the high and low modes on this light, but the 48 Lumen low mode is relatively bright and very useful with an 11 hour runtime. No need for the Strobe or SOS in a general purpose light like this, but a "true" low 5 lumen (Nite-light) mode would have been nice.

While the value proposition on this light is great, there are reasons why it cost less. The Fenix E21 uses a Cree XP-E LED. More expensive lights in the 2xAA category use Cree XP-G LED's, which generally are capable of producing 20 - 30 more lumens with similar or slightly better run-times. An example of an XP-G light in the same family is the Fenix LD20. The latest 2 x AA lights being introduced use the more powerful Cree XM-L LED. An example is the Thrunite Neutron 2A (XM-L), which produces close to twice the light output at 260 Lumens with run-times that are pretty much in the ballpark of the XP-G lights. Note that both these other XP-G & XM-L based lights I mention sell for about twice the price as the Fenix E21.... In addition to higher output LED's you also get more switching options with the more expensive 2xAA flashlights.

So this is not the best 2XAA LED light on the market, but a very good flashlight for this price. Read more ›
