<p>我也用P4替换了一个NG750的UWOK，光通量明显超过了L4，但是聚光比原来的Lux III差了不少（当然，还是比Lux V强很多），光斑比较软，没有原来过渡那么硬</p>

<p>我是拿到以后才发现SSC比Lux发光体低0.7mm的，所以没有定购那个铜垫片（功课没做够啊，惭愧），于是解决方法是把MCR27杯挫掉了0.7mm, 中心光斑汇聚度还是不错的，不过周围多了一圈光晕，其实这从发光体的形状也能看出来，LS III的小粒而且清晰，SSC的就比较暧昧。</p><p></p>

说点题外话，觉得SSC的做工比LS要差些，比如发光体前段的透镜，不易清洁，粘。不知道LS的新K2什么时候能批量供应，期待。

是啊，LS拿在手里随便怎么折腾都不用担心，SSC就要小心翼翼的伺候，特别是那个透镜，沾上东西就很难清理……

其实不用锉光杯，我把LED的引脚压低点，在底部多上点导热胶，提高了LED安装位置就可以了，Sandwich Shoppe就是这样改的。

SSC的确不怎么好用，我用它改赛威特CR时，发现电流超过650MA就会变色。而且这个果冻很不好料理.....

<p>的确有可能，偶用锂电直驱，900mA左右可以发现明显变色，但是同样DC-DC电路1000mA,变色不明显</p>

<p> 应该是电流及散热都会有影响.</p><p>只用一只CR123A的电筒.一般是升压电路.因为我手头上只有北斗的浮雕,只有用这个说了.</p><p>用16340可充电电池.最高档电池端的电流是1.8A...用3V电源时.最高档只有1.2A.差足足0.6A.</p><p>LED端电流没有测.估计用16340时,可能会高达1.4A.这时,本身LS的LED的发热已经很可观了.换成汉城LED.一样是这样的电流.不变色才怪.</p><p>散热是重要的因素.估计汉城的LED在高温下的特性不及LS的.容易变色也就是这个原因.</p><p>因为,钛不是良好的导热体.热量不会一下散发出去,在外面有温热感,芯片可能已经超过100度了.</p><p></p><p></p>
