Tšepe ea tleloubu

Flat-bulb steel ke eona tharollo e bolokang chelete e ngata, e sebetsang hantle le e thibelang kutu bakeng sa litlhoko tsa ho thatafatsa lipoleiti. Melemo e ka sehloohong e kenyelletsa tekanyo e babatsehang ea matla ho boima ba 'mele ho fana ka khanyetso ea buckling ka boima bo tlaase ho feta ka li-bar kapa li-angles.
Likarolo tse chitja tsa profaele ea tšepe ea bulbs li bolela hore ha ho na tlhoko ea ho sila pele ho penta, ho boloka nako le chelete nakong ea ho etsa. Ho senyeha ha pente le ho bokellana ha litšila tse senyang le hona ho fokotsehile, ho lelefatsa ts'ebetso ea bophelo.
