小弟閱覽各位師兄開箱文多篇，今日大膽試寫一篇，望各位師兄多多包涵
先抄抄官方網頁內容：

此燈除前面透明膠片及背板選擇制為塑膠製造之外，其餘皆為鋁或金屬制。包裝內有小配件，用於配合不同鎗身軌道，如1913、Glock/universial、S&W與及M92F。此燈操作與Insight M3相同，可左右手操作。當面向背板，左面選擇制推上為長亮；推下為暫亮，於放手後回位並熄滅。右面操作則為相反。雖然有說TLR1大小與M3一樣，但請留意TLR1 左面有一頗為大的鑼絲，用予調教闊窄並扣合軌道。我相信市面上能夠配合M3鎗燈的鎗套有可能與TLR1不配合。
TLR1 HL號稱有630流明光度，我沒有儀器量度，未能知其有否誇大。但曾與Surefire X300同時比較，發現TLR1 HL比較偏黃，光度比X300真的光亮不少。TLR1 HL持續時間只有不足一個半小時，未免是一大缺點。
