เห้ย ไฟกระพริบ

มันกระพริบได้เวลาวิ่ง ไม่ใช้ถ่าน เยี่ยมยอดไปเลย วิ่งไปแล้วรู้สึกรักษ์ไปด้วย


ขอขอบคุณประสบการณ์ในการใช้หลอดไฟแบบกะพริบ (ไม่ใช้แบตเตอรี่) สำหรับนักวิ่งรุ่น Motion Light ความพิเศษของตัวนี้คือไม่ต้องใช้แบตเตอรี่ ใช้กันเพลินหายห่วงเลยครับ และยังเป็นการช่วยลดมลภาวะที่เกิดจากแบตเตอรี่ได้อีกด้วยครับ

Best red blinking light for night run

I like the waterproof housing especially when frequently washed together with my waistpouch. I also like the long lasting light source without the need for batteries.

Flashing light for running

This doesn’t flash when I run. It’s really disappointing so I can’t use it.

great product

Works well and useful when running at pre-dawn or night. The lighting is quite bright. The clip take some get use to but once u get the hang of it, it’s quite easy. Best part is that it doesn’t need batteries and is completely sealed. So no issue running in the rain or washing it.

Could be a life saver

It really works and it's quite bright. Totally sealed means u can wash it after use. The clip is a bit tight and not easy to clip on thicker clothing. Other than that, it's super. I hope they make a white LED one and I will buy it and wear at the front.

Versatile, useful and well-designed, although a little pricey. Used it twice on pre-dawn runs and it works quite well

Runners Tail Lights.

Now the dark evenings are upon us, evening runners need not only head lamps to light their way, but tail lights to light them up for traffic coming up behind them, again these Motion Lights have it all simply attach to the arm or back, I was so impressed with their design and function so easy to use, another great item from Decathlon.

Very useful running light

I currently have to start my training an hour before sunrise and use a Decathlon head torch and flashing red rear light. My wife bought me two of these motion lights for Christmas and they are excellent. They strap securely to each arm and are particularly useful when approaching a crossroads or road junction because they catch the eye and make you visible to others sideways on. It is important to ensure the strap slides beyond the barb under the clip then they will not come off the strap. I have used them for two weeks and they work very well and are quite comfortable. A very useful and clever light that needs no batteries.

A lamp with no batteries? how does that work?

Do you understand the dynamo principle on a bike?The Motion Light works in the same way but through an oscillating movement: at each stride, the magnet moves into the coil and generates the electricity which lights the 4 red LEDs.The result? A simple and practical running light. No need for batteries or even an On/Off button: just wear it and it will light up at each stride!

Life span and autonomy, this is a light that you will have for a while:

Thanks to its dynamo system, the Motion Light does not need any batteries. A plus for the environment... and for your pocket:We have tested this light in our laboratories to ensure that it will still work after 10 million oscillations, i.e. 10 million strides.10 million strides. Sound good? If you consider that you travel 1 metre per stride, that means a lifetime of over 10,000 km. If you run 1,000 km per year, that means 10 years.Ready?

What lies behind the design of the motion light?

The Motion Light clip has been designed to be attached to thin running clothes: on a loop, pocket, belt, etc. And to give you even more choice, the light comes with an adjustable elastic armband.We have chosen red LEDs because it is a colour we associated with break lights and slowing down. The light can be seen from 100 m, which gives a car driving in urban areas enough time to stop.It weighs only 50 g and comes in a transparent case!

Our design team spills the beans on the development of the motion light

The origins of this product can be found in a simple desire: "we wanted to innovate to remove electronic limitations when running."It then took a team of 3 people, 18 months of development, endless discussions with runners and a commitment: "we were brave enough to say: we are going to make a battery-free product."And after a great number of prototypes, we are proud to offer this simple and practical light."Our idea was that you would run and we would handle all the rest."

A final tip before setting out?

Gilles, product manager and Lucie, designer, have some tips for running at night:"It is important to be visible. Especially when running at night in places where you share the road with vehicles a lot bigger than you! In the end, you need to be visible more than to see. Just as you put your shoes on before running, don't forget your light."And for even greater safety?"Ideally, don't run alone" :)
