1. XM-L2強光電筒 $80
Xm-L2 (T6) 作為CREE廠商的第二代LED燈頭，是現時市面上最好的LED燈頭之一，光度比第一代XM-L的Q5、T6燈頭還要高。有些賣家沒寫明手電筒用甚麼燈珠，就是因為燈珠差就成本更便宜，或賣家自己都不懂。
市面有太多假18650 鋰電池，容量亂標，電芯低質，以國產為主，例如ULTRA FIRE。正貨18650最高容量也只是約3400MaH，假的都敢標到4800MaH，實際容量連1500MaH也未必有，容量不夠的話電筒就不持久，也可能導致電流不穩定而影響電筒工作。假電池的安全性也成疑，例如沒有防爆閥。優質的18650電池目前以日廠松下、索尼、三洋，韓廠三星為主。

1. XM-L2 torch $80
As the second generation of ED bulb from CREE, XM-L2 (T6) is one of the best model, which is lighter than first generation XM-L Q5 or T6 bulb. Some seller don't even specify what LED bulb was used because the cheaper the bulb, the larger the profit, or the seller don't even know the difference.
The Flashlight Touch can be stretch out and draw back, when stretched, the light will be concentrated, while drawn back, the light can spread.
There are 5 lighting modes, the first is strong light, the second is mid-light, the third is weak light, the fourth is quick flickering, the fifth is SOS signal.
the designed Max Light Output (lm) for Xm-L2 is 1052 lm, my phone can only measure 211880lx which should rather be the maximum limit of the phone light sensor.
It use 3 aaa battery or one 18650 lithium battery which is not included.
Add $10 to get a nylon touch bag, which can be buckled on belt.
