[新品報報]:Petzl MYO XP Headlamp
2005/4/13
最近有頭燈需求的山友要注意了，2005年4月甫剛上市的Petzl MYO XP，單顆LED設計，有反射廣角鏡片及強光模式，另外再加上三段式燈源調整(Maximum/70hr、Optimum/90hr、Economic/170hr)，電源不足的警示，最後仍維持著175g含三顆電池的重量和防潑水的功能，如此完美的表現，當然值得你參考看看...
[簡介]
Provides a powerful, even and adjustable white light, with long light duration. A single light source for multiple uses.
[功能說明]
1.Powerful, focused light beam with 3 lighting levels (maximum, optimum, economy) and a blinking mode, to adapt the light to the activity and as a function of light duration needs.
2.Boost mode: 50 % more light than the maximum level for 20 seconds.
Wide angle lens for flood beam-like proximity lighting.
3.Battery life indicator: warns when the batteries are approximately 70 % drained and 90 % drained.
4.Tiltable light body is easy to use.
5.Switches are protected to help avoid accidental operation.
6.Adjustable elastic head band, top strap included (not mounted).
7.Water resistance for all-weather use.
8.Lighting distance: up to 45 m (65 m in boost mode).
9.Light duration: up to 170 h.

動畫和影片介紹都做的不錯喔!

請問這款頭燈台灣有出嗎? -
台灣還沒啦! 包括美國許多知名的戶外裝備網站也都還沒上架呢? 不過REI倒是已經搶先開放預訂了 http://www.rei.com/online/store/ProductDisplay?storeId=8000&catalogId=40000008000&productId=47896098&parent_category_rn=4500596&vcat=REI_SEARCH，不過聽說好像只限定美國國內民眾預購，有興趣不妨可以上網訂購看看售價是us$ 70.-。

奇怪老美和老法都喜歡用AA電池 用三顆AA實在有些重，用兩顆又亮不過10小時 如果是三顆AAA電池就好了(綁在頭上的重量還能接受，又可以亮40小時以上) 希望國內廠商也盡快推出"改良"的產品 -
我覺得他們不完全都用AA電池 應該是要看使用的頭燈結構的設計吧 總不能又要馬兒好、又要馬兒不吃草

我是有一顆很沒質感的LED頭燈(就是那個給山頭捅一刀那個牌子) 只要用一顆AAA電池 其他在美國買的頭燈都是AA電池 不過既然AA和AAA電池的電壓是一樣的 它們只差在容量和重量上 所以只是換個電池盒就好了啊 希望國內廠商趕快殺上去.... 頭燈要做贏老法應該不是很困難

因白光LED工作電壓約>3.5V,故一般多用3顆電池直接供電. 若採用兩顆電池時,必須另外附加昇壓電路, 如此相對電源效率及可靠度會降低一些. 以XP使用3W-LED來說,為達到使用時間實用化,勢必用AA電池, 如果用AAA的話使用時間應會少得可憐吧!

http://tw.f4.page.bid.yahoo.com/tw/auction/d11569873?aucview=search 不知有無山友有用此高亮度LED改裝頭燈之經驗?, 據說亮度關鍵在聚光技術 1W(驅動電壓:3.42V/350mA=25流明) 3W(驅動電壓:3.70V/700mA=65流明 or 3.9V/1000mA=80流明) 5W(驅動電壓:6.84V/700mA=120流明) 其中3W & 5W之照明效率最高,25流明/瓦特(W)

3-watt LED也許真是太耗電了 Battery life at 70 degrees High: 41 hours/ low: 95.5 hours Battery life at 0 degrees High: 7 hours/ low: 27 hours 但是應該可以考慮出個AAA電池盒供使用者替換 如果不是在非常寒冷的天氣使用 AAA電池就夠用了 我有一個MATRIX2 1-Watt LED更可憐 兩顆AA電池只亮8小時
