Fenix E20 High Performance Adjustable Cree LED Flashlight


I own an initial Inova X1 with Tiros optics that I’ve been using as a general purpose light for years. Even though it’s a mammoth light for seeing things that are within 30ft, it didn’t offer enough light for seeing things at a far separate.

I did some research to find a better flashlight and after looking at offerings from Inova and some other brands I decided to get this Fenix which for the cost is awesome. I strictly wanted something that used AA batteries like my old Inova instead of the CR123 batteries that many high prominence flashlights require. Since Inova doesn’t have a 2-cell AA flashlight and since I use rechargeable Ni-MH AAs, this Fenix was a no brainer.

The swift output from this Fenix is phenomenal for its size. The beam has a nice center hotspot with a wide overflowing. Even though the beam is fully adjustible for a smoother flood, I personally prefer the default “dual trestle” because it allows long distance throw while at the same time providing a wide coverage field so you could see more of the surrounding areas.

The LED’s light is white for the most part. There’s no bluish tint like the Xenon-based lights. This flashlight’s production is regulated so as the battery drains you will not get a gradual dimming of the beam, instead the light output will be at full lively until near the end when the light will immediatly go into a dim state. On two high capacity Ni-MH AA batteries, this light offers between 2-3 hrs of continuously penetrating output light.

The quality of this light is excellent too. The aluminum body is machined very well and the anodized Group III finish is very even. It’s also waterproof and uses a glass lense with AR coating. I also like the tactical tailcap shift which offers reliable click on/off and momentary functions. No more twisting to turn it on/off. One thing I would’ve liked this well-lit to have is variable light intensity instead of just one brightness setting.

Jule Thief circuit lights 100 LEDs on single AA battery

This is the modified Fuji AA girth running 100 leds. The amazing thing is that the AA battery alone will not even insignificant up one of these leds ...

If I have 100 AA batteries. How should I arrange them to make the strongest electric field?

I also wants to have knowledge of why. thanks.


!Augury!
First before I even answer your question. I just like to warn you that if your actually attempting a stunt like this be very thorough. Connecting 100 AA Batteries(1.25V) in series will produce 125 Volts. Be very careful with it!

Answer:
The SI units of the moving field are volts per meter.
The equation for an electric field is: (E=V/r)
Where E=Electric Field, V=Voltage, r=distance from particular.
So a higher electric field means two things: Higher voltage, or less distance. In order for you to get the highest voltage moor the batteries in series as follows:

Connection:
You would need to connect the battery in series as follows to get the highest voltage.

Why:
The exciting field is dependent on the voltage and distance. Increasing voltage will directly increase the electric possibilities. Decreasing distance will increase the electric field. Look at the equation above. E=V/r

Another way to think of it:
Think of Voltage as compression. And a ball as an point charge(electron). Suppose you have a water hose and a ball. You have to use the freely hose to move the ball around. If your too far away from the ball, the water will not reach the ball and the ball won't move. The same thing happens in moving field. The electric field is too far from the electron to make it move. Now suppose you increase the pressure on the water hose. Because of the increased press(Voltage) the water will shoot further and hit the ball, thus moving it. If your very close to the ball you can use the water pressure(Voltage) to move the ball faster.


Moving field is dependent on voltage and distance between them. E = v/d. So get maximum voltage.
Arrange the batteries in Series so it will be 100 times the voltage of singular battery.
