抱歉問個問題 我本以為這是純白光的
原來是帶些微黃色的中暖白的
是嗎 |

不會吧!小弟也是相信Selfbuilt筒神的測試才購買MM15的耶!
看中意的是MM15高亮檔1950lm續航5.X小時~若真的只有2小時~
那也和Selfbuilt筒神測試的差太多了吧!
若是這樣~這Selfbuilt筒神的公信力~當之有愧~ ...

Selfbuilt筒神應該不曾唬爛的... |

Selfbuilt的道歉文出來了UPDATE MAY 20, 2014: First off, a MAJOR apology to all who have been following the development of this model. I accidentally mislabeled some of the runtimes in my testing of the second prototype review. Normally, that would only have been a minor error on the figure legend. But because the MM15 doesn't completely fit inside my lightbox, I do a calibration adjustment to get the right output scale. This means that the wrong adjustment was applied to several of the prototype #2 runtimes, giving the wrong output level on the graphs.
I am truly sorry about this everyone. I am revised all the graphs below (and in the second prototype review). My thanks again to RedForest UK - it was his current drain data that helped me track down my error. (大概意思是大型手電筒放不進selfbuilt的測光盒,用部分射入測光盒的光推算時發生失誤)
(在selfbuilt與CPF筒友的討論中,selfbuilt承認失誤的真正原因是測試工程機第二版的L5檔(1900流明)續航時,實際上測試的是L4檔(880流明),那個5小時21分的續航實際上是880流明的L4檔)
MM15正式版的測試光通量
MM15正式版的續航曲線
可看出L5檔(1950流明)的續航時間為2小時25分(電池為 2200 mAh *4)
使用3400mAh電池時的L5檔(1950流明)續航時間為 2.4h * (3.4*3.6*4 / 2.2*3.7*4) = 3.6h
很接近我先前用3400mAh電池電量及接近100%電路效率及接近光杯零光損時推算的3.8小時續航上限值.

juplin兄~感謝您追根究底持續追蹤Selfbuilt筒神的評測~
小弟不太明白~這樣說起來小弟那天測試MM15~有可能流明數早已掉到500lm以下了~甚至更低~對嗎? |

tigerpink 發表於 2014-5-28 09:50 MM15的電路不是恆流電路,要同時測光通量(或定點的照度)才知道光通量變化的情形.
而且每一隻(光通量下降)的變化過程不會完全相同,若L5檔能撐到4.5小時左右時,光通量是有可能降到500流明左右.
