This was done backwards from the original so that it would seem right-wise. I did not flip the image. I’m finding i like that style, to learn to do what i want to do backwards.
It also took me numerous several tries to get these three wonderful lines anyplace close. I do not want to begin to show the mishaps and the oops backwards (and even 1 dropped flashlight). Strangely, the ‘signatures’ were the easiest to do because they were just sort of squiggly dots.

Outstanding Value!, April 19, 2010

Amazon Verified Purchase(What’s this?)
This review is from: Streamlight 88851 Poly tac LED Flashlight with Lithium Batteries, Coyote (Tools & Home Improvement)
I bought this light as a replacement for my Surefire 6P. The 6P eats batteries at a ferocious rate and I wanted a more efficient LED light. It was cheaper to buy this light than the LED conversion for my 6P and the bonus is the tail switch on this light vs the twist/ temp on tail cap of the 6P. The click type tail is more convenient and you can still “strobe” this light if you don’t depress the switch all the way. I like this light so much, I bought several more. If it had a squared off surface to prevent rolling on smooth surfaces I would give it 5 stars.

Top Quality Flashlight, September 14, 2009

This review is from: Streamlight 88850 Polytac LED Flashlight with Lithium Batteries, Black (Tools & Home Improvement)
I own many flashlights, mostly LED, and am always looking for the next great one. I wanted a durable bright light based on the newest LED technology. The Streamlight Polytac LED didn’t disappoint. I like the momentary clicky switch which feels very solid and the ability to lock out the switch. The beam is a perfect compromise between great throw and some nice side flood. It’s the brightest light I have at the moment. I like the polymer case, which feels good in the hand. I would recommend this flashlight to anyone needing a rugged bright LED light for camping, hunting, security, work, or household duty.

Fantastic flashlight, April 21, 2010
By Glenn Morse (Iowa, United States) –
This review is from: Fenix LD20 205 Lumen LED Flashlight (Sports)
This version of the Fenix LD20 uses the new Cree XP-G LED (R4), which produces more light for the same amount of energy. Thus, it’s essentially the same as the standard LD20, but brighter at all light levels. The flashlight comes with a belt clip, lanyard, and a really nice tactical belt pouch. The design of the flashlight body has a very “industrial” feel, and is slimmer than the pictures suggest. The narrowest part of the body is only slightly wider than the AA batteries it uses, and flares out at the cap and tail. Personally I find the design unique and attractive, and it fits very nicely in the hand. The machining is top-notch and highly detailed, and has a very high-quality feel to it. The coating is an attractive satin black, and seems very durable (my Fenix daily-carry light (a single-AAA L0D) has been in my pocket for nearly two years and still has no scratches). The lens material is very hard and is seated very securely. The lens bezel has a five notch scallop, so the flashlight stands securely on the bezel, but the rear cap has a two notch configuration surrounding the button for lanyard attachment. This means that although you can stand the light on its base for “candle” type operation, it’s not very stable in that position. I personally never use my flashlights like that, but if you do, you’ll have to be very careful to get it to stand by itself. The basic operation of the flashlight involves two controls, the button on the rear cap, and the screw bezel. The light turns on and off using a full click of the button, with “soft clicks” of the button cycling through the light modes. To switch between the “normal” and “turbo” mode sets, you twist the top bezel slightly. The rotation between the turbo and normal modes is only ~1/8 turn, which was much less than I expected. Although you’ll probably leave it on the normal modes most of the time, the cap is only slightly unseated from the fully screwed-on position, and I feel confident it won’t compromise the watertight integrity of the light. The controls are intuitive once you’ve used it for a few minutes, and frankly I prefer using buttons rather than twist controls. Interestingly, if you unscrew the top bezel, it opens into the top end of the battery compartment, so I suppose you could load batteries from either end. This means that the entire top bezel, containing the LED and all of the electronics, is a single, sealed module, which really seems like a great design. The light output of this flashlight is quite impressive. The Low setting (9 lumens) is more than sufficient for a lot of personal use and all indoors use, and has a ridiculous 71 hour runtime. Another reviewer mentioned that they thought the Low and Medium settings looked the same, and when used indoors, the 50-lumen Medium setting does look about as bright as the Low setting. However, when used outdoors, the Medium setting is clearly brighter and has a much longer throw than Low. The 105-lumen High setting is quite bright for a handheld light. I found it illuminated objects a good hundred meters away, and is really more light than I need in most situations. The 205-lumen Turbo mode is like having a small star in your hands. The illumination and throw is just amazing; it fully lit the ~3 acre area I was using to test the light, and the reflection was somewhat painful when aimed at nearby objects. The light does warm up on Turbo, but that’s not surprising, given the amount of power it’s using. Overall I found it highly satisfying to be able to choose between a high level of battery conservation or a high level of light, with the four primary modes nicely covering all possible situations I could think of. Personally, I’m not sold on the two flashing modes (SOS and Strobe); I don’t really have a use for the flashing modes and I found it slightly annoying to have to switch past them, but I’m sure that if I ever got lost in the woods I’d appreciate them. The beam pattern is unique to the lights I have, and I really like it. The center “spot” is larger than my other lights, and has a very uniform distribution. There’s a slightly dimmer spot in the very center, but it’s only visible on a white wall. The larger center spot makes the light much more useful than a narrow-beam spot, while still having a long throw. Overall, this is a phenomenal flashlight and I’d highly recommend it. The sheer quality of the light is visible in every detail, and it’s a pleasure to use. The decision between the standard LD20 and this 205-lumen model is up to you, but I feel it’s worth the small premium for the additional light efficiency.

LD20 with all modes working., November 15, 2010
By BokkerToff –
This review is from: Fenix LD20 205 Lumen LED Flashlight (Sports)
I want to “shed some light” on the reason why the lowest mode does not work on some of the LD20 R4′s.
If you received a unit where the lowest mode does not seem to work, chances are you received a unit that is more efficient than the others and not broken !
SKIP TO “BOTTOM LINE” SECTION IF YOU ARE NOT TECHNICAL MINDED.
Fenix does not use PWM (Pulse Width Modulation), but true current control to control the brightness of the different modes.
PWM is the process whereby the output is regulated by switching the LED on and off at a reasonably high rate. For instance lets look at an interval of 1 second. If the LED is on for 0.1 seconds out of the 1 second, then it give you 10% brightness. If on for 0.8s out of the 1s, then the brightness would be 80% of max and so on. The LED’s are typically switched at a rate of a few thousand times per second, but the principle stays the same. This sometimes causes people to notice some flicker while operating at the lowest modes.
The current control in the LD20 does not produce any flicker (apart from strobe and SOS 
). Fenix also does not use resistors to control the current, because resistors would waste energy in the form of heat. The active current control is achieved by using a boost circuit to boost the voltage and therefore the current.
Other manufactures uses a buck-and-boost circuit to achieve their modes. A buck circuit is a step down DC-to-DC converter that would give you a lower output voltage than the batteries supplied.
The LD20 uses a boost-only circuit which is more efficient than a buck-boost combo. This is why Fenix lights are the run time kings.
The problem now is that some of the Cree XP-G (R4) LED’s are very efficient and the voltage does not drop low enough because of the small current being drawn. If this happens the LD20 goes to second lowest setting, because it cant reach the lowest.
This is also the reason why you loose lower modes if you use Lithium or NiZn batteries in the LD20. The lower currents can not be reached without resistors(less efficiency) or PWM(flicker) or a buck-circuit(boost only is more efficient than buck-boost combo) with this higher voltage batteries. The voltage drop in low mode on good alkaline batteries now seems to be just above the reach of the current-control circuit for low mode on some units (They draw too little current/Are too efficient).
Those with the “broken” low mode are actually superior to those that work correctly 
BOTTOM LINE:
Use rechargeable NiMH cells. Their nominal voltage are lower than that of alkaline cells. If you use rechargeable NiMH cells and lowest mode still does not work, then send back your unit.
While good quality alkaline cells might give better run times on the lower modes than rechargeable cells, it will definitely not be the case at the higher modes. Alkaline cells can not sustain the larger current being drawn as well as NiMH or NiCD cells on high/max and will be depleted a lot faster.
With Lithium or NiZn cells you WILL lose the lower modes and you now know why.
As the alkaline batteries lose their charge, the lowest mode will start to work.
On rechargeable cells:
1) The charger makes the biggest difference on the run time of the flashlight. Those cheap chargers would leave you frustrated and probable unhappy with your LD20. Not to forget that they WILL cause damage and reduce the life expectancy of the rechargeable cells.
A good charger has an individual circuit for each cell to ensure that the cell is charged to maximum. Cheap chargers use one circuit to charge all the cells at once, leaving only one with 100% charge and the others at varying states of charge.
If you can’t get nowhere near the runtime claims of the manufacturer, it is most likely your charger that is letting you down.
2) Buy Sanyo Eneloop 8 Pack AA NiMH Pre-Charged Rechargeable Batteries Eneloop batteries (or any other low self discharge batteries). They keep their charge a lot longer than regular rechargeables. The quality control on these also seems to be better.
I can recommend the AccuPower AP2020-1 Accu-Manager 20 Battery Charger for AAA/AA/C/D or 9-Volt NiMH, NiCD, or RAM Batteries and the Maha Powerex MH-C9000 WizardOne Charger-Analyzer as VERY good chargers. I own both for a year now and they are…

Seriously?, August 25, 2010
By Gene Hugh “Cuz dat’s how I roll.” (Chicago, so wassup?) –
Amazon Verified Purchase(What’s this?)
This review is from: Fenix LD20 205 Lumen LED Flashlight (Sports)
I own a Surefire L4 Lumamax ([...]). Surefire L4 Lumamax LED 120 Lumens Tactical Flashlight w/ Batteries It uses 2 Lithium CR123A 3V batteries and produces about 120 lumens at maximum illumination. The Surefire L4 typically costs over $150 greenbacks. So you’re like, “Dude, why are you telling about the Surefire when you’re reviewing the Fenix?” Well my friend I will tell you. If you’re not looking to tactically clear a room, train with the local paramilitary militia or be like Les Stroud in Survivorman, then the Fenix is definitely the flashlight for you. Don’t get me wrong, I love my Surefire. I would definitely have my Surefire as a main tactical light, but . . . So here’s the deal. I was tired of paying over $3 every time I changed the batteries for the Surefire. So I started searching on the internets (yes, plural, cuz that’s how I roll) for comparable Surefire quality (but not as expensive) flashlights that use AA batteries. AA batteries are widely available and way cheaper than 3V Lithium batteries. After spending time reading forums and watching youtube reviews for what seemed like 10 years, I decided on the Fenix LD20+ flashlight. When I received my Fenix in the mail, I was so excited with anticipation. I tore into the box like the first person in line for the iPhone at Best Buy. I opened the box, threw in the 2 AA batteries and started playing with it like a dork. I was instantly satisfied with the construction and materials. The throw (flashlight lingo: the distance a beam can be projected and still be usable) was impressive. The extras included was a nice touch. It had a holster, a lanyard, two spare o-rings, and a rubber switch boot. Another impressive feature was the multiple modes. You can, of course, adjust the amount of illumination. It also has a S.O.S mode and a strobe feature. The strobe feature is really nice by the way. I used it on my friends, and they hate it. They run away and use swear words. So you can imagine the effectiveness if used on a bad guy. I feel as a whole the Fenix Digital LD20+ Black Premium R4 is definitely worth the money. [...] NOTE: Keep in mind there are two versions of the LD20. There is the LD20 and the LD20+. The LD20 is only 180 lumens where as the LD20+ is upgraded to 205 lumens and has some extras.

This review is from: Streamlight 88850 Polytac LED Flashlight with Lithium Batteries, Black (Tools & Home Improvement)
I purchased this LED light a few weeks ago. I work for a police department and had the Surefire G2 LED on my issued rifle. I used it at the range and deployed on several other occassions. The light was great!! I purchased the Streamlight LED which is 120 lumens compared to the Surefire G2 which is only 80 lumens, I now have the Streamlight polytac on my rifle and love it. It’s alot brighter, same size as the G2 but half the prize, I highly recommend this light vs. the Surefire G2! I also own the Streamlight Stinger DS LED light. It is also a great light and also very bright.
