强磁场我没有条件测试。关于你担心的温度问题,有一个测试者是这样说的。
I've been working on run time tests on this beast. They're not done yet, partly because it takes so long to do even one...
我已经开始跑续航了,不过还没有结束,一个原因是哪怕光跑一档就太久了。
I have to say, I am impressed by one thing. So many lights are pushed really hard at their highest levels, and doing a run time test means figuring out some way to cool them. With the Legion 2 all I needed was a fan. I had it running for an hour and my IR thermometer shows 78 degrees F. When I opened it up the cells were not warm. I like this kind of design - this thing will put out 700+ lumens of real light and do it reliably, hour after hour, day after day, without overstressing or cooking the LED or the battery.
不得不说,有一点让我很惊讶。无数电筒都把最高档电流推那么高,给他们做续航的时候,得想方设法来降温。而Legion II,一个风扇就够了。我先是最高档跑了一个小时,然后拿红外线温度计测它,只有78华氏度,也就是25摄氏度(F=32+1.8*C)。然后把电池取出来,发现它们一点发热都没有。我很中意这样的设计--不折不扣地输出700多流明,而且日复一日能够可靠工作,绝不用担心随便就把LED和电池摧残掉。
译者注:长时间使用最高亮度仍有风险,因为你夏天没风的时候也得点它。
译者再注:哪怕散热极端不利,电流过高(3A+),LED会形成光衰,但是电路完好无损,一样任劳任怨。这是一个极端强韧的电路。
