4Sevens Maelstrom S12

This flashlight DOES NOT INCLUDE a battery and a charger.
The Maelstrom S12, by 4Sevens, is the new benchmark for ultra compact,
insanely bright tactical and duty flashlights.
It is the smallest flashlight in the world to use the SST-90 LED emitter.
The Maelstrom S12 features both current and thermal regulation
- this means it can take serious abuse and be exposed to harsh conditions,
but it will automatically control its output to protect its own guts.
That means you don't worry about your flashlight - you just use it.
The Maelstrom S12 also runs off one of 4Seven's own special lithium-ion rechargeable batteries.
It's called a 26650 (not included),
and it packs enough energy to power the Maelstrom S12 at 800 lumens for an entire 90 minutes!
The two output modes that the Maelstrom S12 has two output modes that are easily accessible by either tightening the tailcap or depressing the tailcap, for a "momentary on" mode.

The output modes are:
Low (120 lumens, 13 hours)
High (800 lumens, 1.5 hours)

The Maelstrom S12 has a crenulated strike bezel.
The optical-grade glass lens is sapphire coated on the outside,
with an anti-reflective coating on the inside for both optimal light transmission and durability.
The flashlight also features a smooth reflector, meant for illuminating objects far away.
The Maelstrom S12 includes a custom molded carry pouch designed to help retain the light even when flap is open. It also includes spare o-rings.
4Sevens flashlights come with a 10 Year Warranty against defects! Such an outstanding policy shows that 4Sevens is a company you can trust.

Operation:
The Maelstrom S12 features a simple, two-mode interface that takes only a few seconds to master.
To start, please make sure the 26650 battery is inserted with the positive side (+) toward the head.
Then, tighten the tailcap fully down and the Maelstrom S12 will turn on. Loosen the tailcap a half-turn,
and the flashlight will turn off. The Maelstrom S12 tailcap has a pressure-style switch.
When the tailcap is loosened a half-turn, simply press the button on the back to activate the light.
The switching mechanism is momentary,
which means when you stop pressing on the button, the flashlight will turn off.
To 'lock' the Maelstrom S12 on, simply tighten the tailcap fully down again.

To switch between the high and low output modes, turn the Maelstrom S12 off,
and then turn it on again within 1 second.
Anytime the flashlight is turned on within 1 seconds of being turned off,
it will automatically switch to the next mode.
However, if you leave the flashlight off for 2 seconds or longer,
it will "memorize" the last mode used. See the examples below:

Example 1: ON (High mode) --- OFF (1 Second) --- ON (Low Mode)
Example 2: ON (High mode) --- OFF (2 Seconds) --- ON (High mode)

PLJの掲示板で
サイズと明るさが中途半端で、
専用Li-Ion充電池はPSE無理そうなので日本での正規販売は無理です
というか、実際に危険かもしれません。

とコメントされていた Maelstrom S12 です。

SST-90 LED を採用し、26650 Li-Io 充電池を使用した
コンパクトサイズのフラッシュライトで
全長は surefire 6P とほぼ同じですが
ボディが二まわりほどでかいです。

テールスイッチは surefire の Z41 と同様のツイストスイッチです
違うのは、スイッチがゴムブーツではなく
ボディと同じアルミ製になっています。

High mode(800 lumens) & Low Mode(120 lumens) の 2-mode
SST-90 & SMOリフレクター & コーティングサファイアレンズ
モード切り替えは瞬断で
モード記憶は消灯後、2秒以上で最終モードをメモリーします。

SST-90 で 800ルーメン…
PLJでは、明るさとサイズが中途半端とありましたが

実際のところ、かなりの明るさですし
所有している MicroFire TL2 SST-50 の 700ルーメンと比較すると全然明るく感じます
その分、発熱もかなりですが　^_^;
小振りなサイズのライトでそこそこの出力（ハイモード）を…

魅力に感じる方も多いのでは？

と思いました。
