Second, EDC with (EDC every day carry meaning, as a hedge), the requirements of the cheese with a tube than to walk much higher.
1. Cheese type: personal opinion, EDC is the king of AAA. According to different requirements on the volume of cheese with the battery and also different: the most convenient AAA; the brightest and most long-range is 16,340, all aspects of performance are good and most convenient is to buy batteries AA; life is the longest 18650 straight cheese.
2. Required to achieve brightness: EDC with the cheese and cheese usually walk a lot in common, the difference is only in the case to achieve similar performance, requirements must be small enough for easy carrying. So personally think that the EDC's cheese requirements than walking with a tube is much higher. EDC is also a feature of most of the time just a few seconds or minutes light, without considering the heat when lit for a long time, so I mean, EDC cheese power must be large enough to light before SAO good, so all the cheese cheese EDC's most complex and difficult election. General requirements for lithium-ion batteries, the current is to be able to reach 750MA 3W; when using other ordinary batteries, the current to achieve the kind of battery can achieve close to maximum output for the job in general LED 2W less power consumption.
3. LED light color: white light can be used, because the white light so bright and dazzling, bright light better than the warm SAO.
4. With a variety of battery life: the pursuit of highlight to use a variety of lithium batteries. Power consumption in the LED 3W, current 750MA, a variety of lithium following the flight time: 18,650 in three hours of battery life; 16340 or 14500 in 1 hour battery life; 15266 or 10440 life in 20 minutes; the pursuit of middle power and common good, to be able to buy a small shop with all the common battery. Use rechargeable AA batteries, the discharge current is about 2A, the life time of about 1 hour; with the capacity of high-quality alkaline AA batteries 2200MAH, discharge current 1A or so, about life in the last 2 hours (if the current 2A 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 drawback is often in the EDC benefits: Who can guarantee that when you are need to use flashlight, your torch is just enough electricity it, when your little power, the 7135 provides the circuit is just dark light, at least deal about it. 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, low, strobe, SOS, best group, anyway, is to sum up the case in a group, the more complex the better gear. Most used, or high, in second gear.
7. What Light Cup: head diameter, such as straight and the use of 16340 18650, and recommended a lighter orange side 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 head is smaller, such as the AAA's cheese, it is proposed that higher rates of smooth reflective cup cheese, a good cup of smooth also in the AAA to form a spot near, there is a bright spot is quite useful.
8. Required to achieve the appearance of the treatment: we must wear, such as stainless steel, titanium, or HAIII, or else a few days to only five EDC into a new, and want to transfer can not afford to have changed hands.
9. Waterproof performance requirements: to prevent heavy rain shower can be, if you want to SAO that can be soaked in water to buy a MM to see the performance, of course, make the cheese was prepared to give MM's look to her.
10. Price: according to their own economic strength, the general choice of cheese a little more expensive, after all, follow their own day, high utilization, of course, starting a good point.
11. Recommended cheese:
