真っ白ではなくちょっと黄色めの光ですが明るさは申し分なく、操作も最近多い面倒なナントカUIってやつがないシンプル操作なので自転車用としては全く問題ないのですが、やはり3000ルーメン以上あるとバッテリーは18650では容量足りないなぁと痛感しました。付属バッテリーを満充電にして夜ちょっと買い物に出て家の近所まで戻って来た所で点滅して減光したのでバッテリーの残量が少ないのかな？と思ったら少し経つと完全に消灯してしまった。21700を使うライトだともっと持つのでこのライトは低〜中輝度で日中の雨降り用にすることにしました。あとスイッチが軽いのでバッグやポケットに入れてるとうっかり点灯する可能性大、というか実際に点灯したので焦る。バッグの中などわからない状態ではなかったけど、別のスイッチが軽くロック機能がないライトでズボンのポケットやライトホルスターが熱であっという間に溶けてしまったことがあるので。Sofirn SD06みたいにロック機能があったらよかったのですが。

The Wurkkos D-70 is an absolute powerhouse of a diving light with an array of 4 XHP50.2 LEDS. The user interface is straightforward with 4 stepping levels low, medium, high and turbo up to maximum brightness. The 13000 lumens in turbo mode is the real deal. I have had a lot of powerful flashlights but this unit, powered by two big stacked 26650’s in series is in a class of its own. It’s amazingly bright.A diving light must be sealed so there is no on-body charging port. It comes with a USB C cable and charger that holds two 26650 cells which you remove from the light to charge. Under turbo mode the power draw causes the light to heat up quickly and limiter circuits will kick in to reduce lumens if it runs too hot. In low mode, the light gives you approximately 450 lumens for around 18 hours,As to accessories it comes with the aforementioned dual 26650 charger, a USB C cable, silicone seal replacement “O” rings, an operation manual, and a nylon lanyard strap you can attach to the light while diving to keep it tethered to your body. Build quality is very solid. The body is made of machined aircraft-grade aluminum with a segmented pattern on the tube body section for getting a good grip. Weight is about 1.3 lbs with batteries. You could use it to defend yourself as a short club if need be. For maximum lifespan and waterproofness, the switch is magnetic. As an interesting party trick, you can turn the light on without touching it if you bring a powerful magnet within a few inches of the switch. It claims a 100-meter depth rating, but I’ll take that on faith as I have no way of testing that. Interestingly, while heavy and solid it’s not that big dimensionally at 8 inches long, so it’s relatively easy to carry. It will not stand on its end as an LED “candle” as the lanyard hole is an oval ring cast into the butt cap of the light and does not provide a flat surface, but this is not an important feature for diving light.Overall, a very solid and dependable light from a dependable company. I own a bunch of Wurkkos flashlights and they have all been top performers, especially for the money.

Wurkkos built a home run diving light with this light. This has some improved features over other dive lights and even some older Wurkkos diving lights. The top 3 features that stood out to me are listed below:1) USBC Charging built in - This is a major win and better than having to use a charging adapter.2) Double O rings to help prevent water from getting into the light. Wurkkos usually does this but I feel this for their dive lights but I think it's vital so that if one o ring leaks, the other could prevent water from shorting the light. They also include some extras so you can inspect them after use.3) Longer head which gives more of a spotty beam instead of a floody beam. This is so vital for underwater when you are kicking up sand and muck. A flood beam will make all of the particles in the water reflect and you won't see anything. This having a spot style beam allows you to see what you point the light at. This is so helpful for water use.Generally speaking, this light is great. It's got a commanding hand feeling that screams quality. The button actuation is really smooth and uses magnets so it'll work well in water. The light is a neutral white which will be great for true color reproduction (think fish spotting or looking for coral). My only complaint about the light is the long charging time, but with a large battery, that's to be expected. It could have also been my charger too, so I guess I can't really fault the light for that.This light is clearly for divers and people who will be using this in the water but if you live in a place that gets a lot of rain, I think this could be a good option for you as well. This would be a perfect light to keep in a boat or jet ski or even in the back of your truck where it may get exposed to the elements.

潜り漁に使用しているが使いやすく、明るく、耐久性が高い。予備で２本目を購入してしまった。一番明るいモードは使うべきではない。すぐに電池残量が無くなります。水中以外でも活躍できるが、一番明るいモードは高音になり、壊れないか心配になるレベル。

I am absolutely satisfied with the dive lamp.The workmanship makes a very good impression. The scope of delivery includes 1 pieces batteries, charger, O-ring, and lanyard.I bought the lamp on the recommendation of an acquaintance who has been using this lamp for a long time. torch output max 2000 lumen, bright but small, easy to carry and operation.

After having this light for a short time now, and using it in daytime, nighttime, and underwater, I have to say, I’ve come to love this light. It is very well built, feeling very durable in your hand. This light originally appealed to me due to the fact that it is built for deep sea diving. I do not do deep-sea diving myself, however, I wanted to have this light due to the fact that has extreme water resistance. I wanted to add a light to my collection that I could take basically anywhere outdoors and not have to worry about it getting ruined (to the lake, beach, etc.). I am happy to say that it has survived everything I have put it through this far.Another thing that was amazing to me was this flashlights battery capacity. It uses and ships with two 26650 batteries as well as a charger for them. On low setting, this flashlight is rated for almost 30 hours of constant usage at around 300 lm which has been adequate for most of my needs so far. This does not have USB-C charging capability built into the flashlight allowing for better water protection. This flashlight also comes with some inserts to allow for use of two 18650 cells which is appealing to me because I have lots of those batteries around right now, so I can use those as spares if needed. Another cool thing that I have come to really enjoy with this flashlight is it’s magnetic switch. This is definitely unique and I have not used a flashlight with anything similar. This magnetic on off switch provides a near complete seal from outside the light. It is also very fun to actuate, and I wish they would use these in other flashlights as well.I think this flashlight produces a ton of light, I do not know if it fully reaches 5000 lm, but it is easily brighter than my FC 12, and TS 11 flashlights which have outputs of around 2000 lm. I would describe the beam as a good mix between flood and spot. It’s overall throw is much less than a TS 11 and even the FC 12, but has much better flood capabilities than either flashlight. This light is very large, and feels hefty while holding it in your hand. It honestly feels like that you could use it as a hammer due to how well built it feels while using it. This is definitely not an every day carry flashlight as it is too large to fit in most pockets, but this is not what it was intended for. I have found that I enjoy using it in the early morning or late at night going on walks or walking to my car.This flashlight fits into my life for a few reasons. I plan on using this light to assist me in my outdoor activities, including: walks, hikes, camping, going to the beach and the lake. I think this will make a really good emergency preparedness flashlight as well, especially if you live in a flood prone area as it will easily survive those types of scenarios. I have also really enjoyed showing this flashlight off to others as it looks and feels really cool and gets a lot of compliments.Overall, I would highly recommend this flashlight to anyone who is worried about having extreme water resistance, and a very durable and rugged flashlight. It is very bright and has a very long battery life, and is compatible with the 26650 and 18650 batteries with the insert so spares are fairly accessible.

This torch shut off when I was diving and didn't turn on again. causing me panic seeing fetch black under 12 meters deep. Good thing I have my back up torch.
