SC53c AA Neutral White High CRI Flashlight

Cree XP-L2 EasyWhite LED
Nominal CCT 4000K
Typical CRI: 93-95
Tint deviation: 2-step
User Selectable Levels: 3 main levels (High, Medium and Low). Each main level can be programmed to one of its two sub-levels. The second sub-level of the each main levels can be further programmed to different brightness levels.
Light Output (runtimes)
High:       H1 285 Lm (0.9 hr) or H2  238 Lm (1.6 hr) / 171 Lm (2.3 hrs) / 106 Lm (4.2 hrs)
Medium: M1 56 Lm (8.5 hrs) or M2 26 Lm (21 hrs) / 10.3 Lm (41 hrs) / 3.5 Lm (4.5 days)
Low:       L1  1.0 Lm (13 days) or L2 0.26 Lm (1.1 month) / 0.06 Lm (2.2 months) / 0.01 Lm (3.3 months)
Beacon Strobe Mode: 0.2Hz Beacon at Low / 0.2Hz Beacon at H1 / 4Hz Strobe at H1 / 19Hz Strobe at H1
Light output are ANSI out the front (OTF) values. Runtimes tested (and parasitic drain estimated) using Panasonic Eneloop Pro AA batteries. Remaining battery power, about 10-20%, after step-down are not counted towards the runtimes.
Operating Voltage Range: 0.7V - 2.0V
Battery: One AA size NiMH, lithium or alkaline battery. Panasonic Eneloop or Eneloop Pro is highly recommended. Batteries are not included in the box.
Parasitic Drain: Negligible (much less than the self discharging of a battery)
Beam Type
80 degree spill
12 degree hot spot
Dimensions
Head Diameter: 0.96 inch (23.6 mm)
Length: 3 inch (77.6 mm)
Weight
1.4 oz (40 gram)
Features
Battery capacity indicator (LED flashes 1-4 times, 4 short clicks to start)
All levels are current regulated
Low battery alert when the light is switched OFF (LED flashes if the battery voltage is below ~1.06V)
Automatic stepping down from High to Medium, and from Medium to Low when battery capacity is low
Durable electronic soft-touch switch
Smart user interface provides fast and easy access to all brightness levels and beacon-strobes.
Precision machined unibody casing from premium grade  aluminum bar stocks
Proprietary heat sinking design bonds the LED board directly to the unibody aluminum casing
Durable natural hard anodized finish (Type III Class I)
Sealed and potted LED driver circuitry
Tempered optical grade glass
Preinstalled optical grade glass
Orange peel reflector
Battery power can be disconnected by slightly unscrewing the tailcap to prevent unwanted activations or parasitic drain
Waterproof to IPX8 (2 meters, 30 minutes)

這......該怎麼說呢！雖然我喜歡SC53的外型

捨棄 14500或許問題不大，但最高亮度和 H53 一樣差 SC5 一截就有些小失望。因為開關位置的關係， H53 似乎更細一點，外型我更喜歡…

斑馬這一系列似乎差異不大,
除了更小的體積,略大的中心光斑(相對於SC5 MKII的10度,
使用較低的H1亮度來達到不會降檔的目的(H1 285 Lm 0.9 hr),
唯一比較特別的大概就是多了
Low battery alert when the light is switched OFF (LED flashes if the battery voltage is below ~1.06V)
當電池電壓低於1.06V時,關閉手電筒時LED會閃爍提示.
以及沒有電池物理防反接(不確定是沒有還是漏掉標示)

依 CPF 上的引述的官方說法是，記憶體/筒身大小放不下對 14500 支援所需的電路與程式，且要達到像 SC5 的亮度需要更高價的驅動電路…

led如果用XPG3 那會更好.

成本考量嗎?比起SC5 MKII的售價69鎂,
SC53的57鎂應該還有調整的餘地,
可能定位本身就有差了吧.

至於14500支不支援,其實不是很在意啦.

我比較期待 SC5c Mk II 這把，
不知波大何時辦進來。
