近く用だったら電球より使いやすい、

Lighting This has a bright and wide flood light, not a spot light. The light is great for construction, painting, carpentry, plumbing. Sometimes I don't realize how dark the areas I'm working on are until I shut it off. It has High, Low, Red and Red blinking that cycle through the same button. Sometimes the person I'm working near uses my same light because their headlight is washed out by this one. The button is placed in a way that it hasn't gotten accidentally turned on in my tool bag like most of my other headlights. The front tilts and clicks in place at different angles. The lamp is high enough and has a rubber edge so I don't get glare from the light on the top of my glasses. Batteries The rechargeable batteries it comes with are high quality. I think I can work 3-4 hours on the highest setting before it quits. The batteries charge slow (like overnight) if you leave them in the unit and just charge by plugging in the usb. I bought a backup pair of batteries and a charger which goes faster, but the backup batteries don't last as long as the original batteries that came in the lamp. Comfort It's a little heavy compared to other headlight but that's a trade-off for having two 18650 batteries. It is balanced with the batteries being opposite the lamp. It could use a little more padding in the front because you have to tighten it to keep it from falling off when you have to look upside down and sideways a lot (like working on a car and some plumbing). I usually wear it over a backwards baseball cap. Durability The clips are plastic but are holding up so far. Mine has fallen a few times from different height and I've banged it on things and so far it's fine.

夜間の昆虫撮影、特にクワガタやカブトムシの写真撮影にはどうしてもLEDヘッドライトが欠かせないのですが、通常の光（白色LED）では、光量を落としても嫌がって逃げてしまう個体が目立つので、調べたら赤色の光は波長が彼らにとって感知しにくいとのこと。そこで検索した結果、本商品がヒットしたので購入し、到着したその日の夜間撮影に試してみました。結果は極めて良好で、赤色発光では逃げられることなく撮影することができました。発光部が幅広のため、通常のヘッドライトに比べて広い範囲を照らすことができ、白色発光の50％発光モードであれば、夜間のウオーキングでは十分な視界が確保できるうえに、こちらの存在を知らせることができます。

These are noticeably brighter than my Petzl, but battery only last on high for 3-4 hours. Bought these for caving, and they work very well for that, but you will need atleast 2 of these, extra batteries, plus a battery powered backup. For what they are, these are absolutely fantastic, and conpete even with the top caving brands for brightness. Lights up the caves very well.

the light is very bright and the battery lasts very long
