Buy LED tube for ten minutes novice entry (just to see what you need)


A good flashlight, the flashlight is not an expensive nor a good flashlight work. Only for their own use, is the best.
Never touched the LED flashlight to make a novice can quickly find their own cheese, so you buy a flashlight from below, the purpose and requirements to write. You only need to press your request to find the headline, you can find what you need for your cheese. What is the science for issues such as LED, you can search the old posts before. This quote can talk about LED flashlight in the hand, talk about light beads or large portable lights.

Always said: You need a flashlight, then there must be reason to need it. This required the use of talk about:
The following title is duplicative, please see end-use category, and then pick the most appropriate to see:
Title:
First, the walk light with a flashlight (which requires a good pan of light, color is good)
Second, EDC with (EDC every day carry meaning, to prepare for contingencies)
Third, the outdoor search with the (hunting, etc., need to highlight, required long-range)
Fourth, vehicle use (never on the car, useful when easy reach of the cheese)
Fifth, use the flashlight to give MM (MM'll think of you in the evening)
Sixth, strong attack or self-defense with a flashlight (pure YY, non-professional not to enter YY)
VII)
VIII)
IX)
X.)
XI
Second, storage backup-type flashlight (Preparation prepare against natural disasters)

Note: This article refers to the said 18650 3.6V (fully charged 4.2V) 18650 cylindrical lithium battery, the capacity that are 2250MAH;
16340 refers to 3.6V (fully charged 4.2V) of the 16340 cylindrical lithium battery, the capacity that are 750MAH;
1.5V AA battery is the 5th of the usual battery or 1.2V rechargeable battery, the capacity is generally 2250MAH;
1.5V AAA battery is normal on the 7th battery or 1.2V rechargeable battery, the capacity is generally 750MAH.

First, take out only, only for lighting when walking, in general, requires adequate flood light, light medium, color is good. Not ask for much of the cheese.
1. Cheese Type: You can use the 18650 straight (high power, high brightness, following the flight time of about 3 hours), or higher power of AA cheese (battery available everywhere, easy to carry, following the flight time is about 1 hour).
2. Required to achieve the brightness: walking on a flat road less demanding on the brightness, a power of more than 1W AA cheese enough, if AA rechargeable batteries, then use the power of big points, such as battery-side current of about 2A cheese, LED side of the current general can achieve more than 350MA, LED power consumption at 1W or more. If the preparation has been using the AA battery can not charge to use the power of small points, such as the battery terminal current of about 1A is better, LED side of the current is generally less in the 300MA, power of 1W or less. If the dirt road in rural or mountain mountain, I do not recommend using AA cheese, the best starting a 18650 cheese, current of 750MA, LED power consumption is about to 3W.
3. LED light color, dry conditions in the road with a white LED on the line, if it is wet and slippery mountain or in the case, it is best to use warm white or natural white color LED to increase at the same time, can a big power with a power point of the cheese to cheese, after all, safety is most important.
4. A variety of battery life: the pursuit of highlight to use the 18650 lithium battery, power 3W, current 750MA of the cheese, sufficient, and life in three hours; use rechargeable AA batteries, the discharge current is about 2A, the battery life of about 1 hours; with high quality alkaline AA 2200MAH capacity of the battery, the discharge current 1A or so, about life in the last 2 hours, if 2A current discharge on the very economic, often only half an hour highlight; AA batteries with garbage, 1A discharge nor economic, preferably 500MA current discharge, battery life can reach about 2 hours.
5. What Circuits: 18650 7135 tube is best to use the composition of constant current circuit, with the boost circuit is not recommended because the 7135 circuit the most stable, high efficiency, constant current circuit 7135 is when the voltage is low disadvantage to a certain extent, the more with lower brightness, this defect has little effect on walking. For AA cheese, it would only boost circuit can you, best to use good quality and high efficiency, to save power to extend the life purpose.
6. What the circuit to stall: high, medium, flash burst third gear more practical. Strobe is mainly used to remind people use when crossing the road.
7. What Light Cup: Because the requirements of the Pan-light is good, it is recommended to use the orange peel cups, and the best surface to a lighter orange cup. Reasons why to use a lighter, not only refers to the relatively shallow little condenser, also refers to the LED light from the light to have more direct injection without a reflector reflecting out. Without a reflector reflecting the advantage that the lower the efficiency of orange peel reflector, and some can only reach about 70%, it is not after a little reflection will be bright. When using the cheese power is smaller, I do not recommend the use of orange peel cups of the cheese, but with a little higher rate of smooth reflective cup cheese, of course, refers to a lighter smooth cup.
8. Required to achieve the appearance of the treatment: according to personal preference.
9. Waterproof performance requirements: to prevent heavy rain shower can be.
10. Price: according to their own economic strength, the general selection of cheap tube suffice.
11. Recommended cheese:
