Eight verstible modes of output are accessible by rotating the head. A completely silent 4-point switch allows switching modes without detection, ideal for tactical situations. The most commonly used modes of output placed as the first two positions (tight and immediately loosened) for Max/Strobe and High/Medium.
Generous knurling throughout the entire light ensures confident grip even in the messiest of situations. Removable grip ring, clip and crenated stainless steel strike bezel. A flat black aluminum bezel and grip ring replacement are included.
Shock-mounted battery design fixes the batteries inside to the body of the light, avoiding self-destructive battery movement. The light is ready to be weapon mounted.
Patent-pending anti-rattle design that accomodates both 2xcr123a and 1x18650 without the need of spacers or adaptors. A custom molded holster shaped for the G5 is included - designed to help retain the light in holster even when flap is open.
A tactical 'clicky' switch is fully exposed in the tailcap for easy access, even when wearing gloves.

いつものようにフルオプションです。

サイズ的には大柄な部類になります。

ナーリングは荒目でグリップ良しです
OLIGHT M20 に似てます(笑)
個人的には同じ製造元のブランド違いなのではないかと思ってます
他にも思い当たるブランドがいくつかありますね。

フォワードクリッキースイッチ。

モード切り替えはツイストで緩めていくとハイからローに移行します
ストロボ系への切り替えは緩めて締めるを4回続けると移行します
4つの接点でモードチェンジするようです

スムースリフ & 大口径ヘッドの組み合わせは
かなりのスポットです
メーカー公表値 350 OTF lumens
十分な明るさのタクティカルライトです。
