Torcie a led, chiarimenti
Ciao a tutti,
sto per acquistare una torcia, potente e con un fascio ben stretto.
Sono andato a cercarla su ebay più precisamente quelle provenienti da hong kong.
Purtroppo non posso postare il link di quelle che hanno suscitato il mio interesse, ma posso mettere titolo e specifiche tecniche...
La prima :

E qui nascono i dubbi, è possibile che questa torcia abbia una "potenza" si 2000 lumen?
il fascio di luce diventa troppo largo se la torcia in questione utilizza 3 led? quindi se il mio obbiettivo è illuminare a distanza dovrei cercarne una a un solo led cree?
Il prezzo di qest'ultima è di 28 euro più bisogna comprare a parte 2 batterie da 3.7 non inculse...
