Even in extreme situations this will survive, full use of the capability that the small waterproof light "e light" is not hesitant

When going to the outdoor by camping and fishing, of course, there is also one as disaster prevention goods a safe headlamp. Unlike the flashlight used by grasping in the hand, since both hands are free, it is possible to work in the dark and it does not hinder walking, but there are various merits such as similar products It is also a fact that it is overflowing and it is difficult to understand which is better.

Therefore, this time we examined various uses assuming applications such as lights when power outage due to earthquake and typhoon, lighting outdoor and lighting at hand at night, the headlamp satisfying the following conditions is not superior I came to the conclusion that.

· Lightweight and compact
· Waterproof
Easy to operate even with gloves
· It can be continuously used for more than 1 week even if it lights about 5 hours a day.
· Even if it is stored for a long time, the battery will not run out

Considering such conditions, I searched for a corresponding product, Apparently Petzl (Petzl) 's "E light(3885 yen including tax) "is like the best product, so I tried thoroughly checking the brightness, toughness, usability etc actually purchased.

The package looks something like this. It has become a design with a red cross as a motif, and indeed it has become an impression "in preparation for emergency".


When looking at the specifications on the back side, the brightness is 16 lumens, so be careful that it is not a product that emphasizes lighting over a long distance or a wide range.


The contents are a light body and a container for storage, and an instruction manual.


You can see that it is very compact with such feeling when put on hand.


The measured weight including the battery is about 28 g and the lightest class as a headlight.


Actually wearing it on your head is like this.



The overall image of the product looks like this.


The band to fix is ​​stretchy, and there is not such a thing that the head hurts because it is too hard but an exquisite level that the fit feeling is not impaired.



You can adjust the degree of closing freely with fasteners on the back of the head.


The fastener doubles as a whistle, and in emergency it is possible to call out with a loud noise with this.


There are written "three short sounds, three long sounds, three short sounds" which are worldwide signals representing "SOS (rescue signal)". In case of an emergency, if you blow a whistle like "beeping, going beeping, and going beeping" accordingly, it will be a more accurate distress signal.


It is also possible to put it on a flat place as follows.


The pedestal and the light part are "ball joint" same as those used for figures and other joints, so you can adjust the angle freely.




The pedestal part is also a clip, it can be pinched in various places and can be fixed.


When attached to the belt it looks like this.


It can also be attached to the backpack shoulder strap.


The back is like this.


Since the groove on the back of the battery box matches the size of the protrusion of the band fastener, it can easily be opened and closed securely without special tools.



Rubber packing is attached to the lid of the battery box, so even if it is 1 meter deep, it will operate without problems. In addition, since it can be used in environments ranging from minus 30 degrees to 60 degrees, we can respond to almost any situation as far as we can use it in Japan.


Power source uses two button lithium batteries. According to the vendor, it is a battery that is hard to leak or spontaneously discharge, so it can be used without problem even after long term storage. According to the notary data, it seems that it can be lit even after preservation for 10 years.


Continuous usable time is as shown in the table below. In the economy mode that illuminates eleven meters ahead, it can be irradiated for about 45 hours, even if you continue to use 5 hours a day, you can continue using the full 9 days.


Let's put it in a special case.


After closing the lid, you can stop it with a rubber band so you can get out of the container inside the bag and prevent the accident that the switch will come in and it will run out of batteries.


The weight of the case is about 46 grams. Easy to carry because it is very lightweight, less than one-third of "iPhone 4S".


Illustration of a hand signal that can be used in emergency is drawn next to the case. If you mention both hands "SOS", the left hand raises "It's all right, no problem", so it may be nice to remember for emergency.


To turn on the light, move the knob counterclockwise on the left as seen from the front.


Since the switch is made larger, it can be operated even when wearing cotton gloves, so it is convenient when used in winter.


Initially weak white light. Since the LEDs of three lights are emitting light, it is bright enough to be viewed directly though it is weak.



Next is a strong white light. This level of light is enough to illuminate your feet and a little bit.



I feel like this when lighting the book at hand.


If you illuminate with too much light in the darkness, you can not see the part where light does not reach at all, so you can keep the field of view wide by lighting with weak red light. If you set it to blinking mode, you can use it continuously for about 70 hours, so if you do not have a light in the surroundings you should be able to see it even from quite a distance so it is an encouraging spec when using it as a rescue signal.



The movies that actually check the brightness while switching modes are below. The switching order is white light weak → white light → white light flashing → red light flashing → red light.

As it is said to be 1 meter waterproof specification, I put it in a bucket's water, and it turned on without problems even if I left it for about 3 minutes.
