COB Floodlight Headlamp USB Rechargeable with Red Light, 2000 Lumen LED Headlight - Car Maintenance and Night Construction 6-10 Hours Long Battery Life

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。

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.

This light is very well made. Its very bright and lights up the complete area around the user. The battery life is surprisingly good and the charging is rather quick.

仕事用で商品する為購入とても明るく手元が見えてこれからの季節には重宝します。実際使って見て耐久性はどうかなと思います

まあまあですかね。もう少し電池の寿命があってもう少し明るい方がいいですね
