Benefits:
+ Extremely high maturity with two normal D alkaline batteries (> 100 hours = 5 days non-stop)
+ Fairly light (not a big difference to 1 W LED bulbs), headlight range is also ok
+ Reasonably priced
Disadvantage:
+ To read too heavy and too light
+ There is only one luminosity
+ Light Focus can not be changed, indoors it is best to light up to the ceiling to illuminate the room evenly.
Although I own quite a few LED lamps that have either lighter and / or more easily and focus, but not so high, the duration, and with an acceptable weight and excellent brightness.
For reading in the tent but I would recommend a headlamp.
The lamp I have purchased for emergencies, because you virtually never have to look after the batteries. In long-term test, it was fascinating to watch how long the lamp still burning with sufficient brightness.
By means of a photoluminescent tape I have the lamp still "jazzed up" to see in the dark also can.
Highly recommended as a household flashlight for emergency and / or for the car and weekend house, but there is the 5 star.
