Bateri ntoya yasimbuwe n'urumuri rutukura rw'amatara ya LED

Iri tara ni rito kandi rifite imbaraga, rikoresha batiri ya 2AA gusa. Ni rito nk'igi kandi ripima garama 25 gusa, bigatuma byoroshye kurishyira mu mufuka. Waba uri umwana cyangwa umuntu mukuru, ushobora kurimbara byoroshye nta mutwaro.
Ikintu gikomeye kiri muri iri tara ni imiterere yihariye y’urumuri rw’umweru n’urutukura. Itara ry’umweru rigufasha kubona neza byose mu mwijima, mu gihe itara ritukura rishobora gukoreshwa mu bihe byihutirwa cyangwa mu gihe cyo gusura nijoro kugira ngo rimenyeshe abagenzi baryo. Ubwoko bubiri bw’urumuri bushobora gukoreshwa ukwabwo cyangwa icyarimwe, kandi bushobora guhindurwa bitewe n’ibyo ukeneye.
Byongeye kandi, igihe bateri y'iri tara ryo hejuru imara ni kirekire cyane. Bateri zisanzwe zishobora gukora amasaha agera kuri 15, bivuze ko ushobora kwishimira urumuri rurambye mu gihe cyo gushakisha no gukambika mu ijoro rihoraho.
