I do not know anything about flashlight.

 

However, recently I have a chance to do some research into the LED torchlight.

 

That is really eureka moment for me.

 

I come to know that some people collect LED flashlight, and that the brightness of the LED flashlight is measured in lumens.

 

1000 lumen LED flashlight is as bright as the headlight of the car.

 

Can you imagine carrying a torchlight as long as a pen, and can shine as brightly as the headlight of the car?

 

It really amazes me of the things that are selling in the market.

 

Perhaps those people who face frequent blackout or always go for camping trip can bring along a 1000 lumen LED flashlight.
