fuck the internet. Normalus draiveris stabilizuoja srove ir konvertuoja galia. Tai impulsine technika. Minetam XMLui max srove iki 3A, prie tokios sroves diodui reikia tik 3.3V itampos. T.y. 10W. Pridedam impulsinio draiverio nuostolius ~10%, gaunam 11W. Imant dvi batareikas su 3.8V itampa (7.6V), P=UI, Srove is batareikos 1.45A. Nereikia cia blia jokiu 2A. O jei imsi kiniska fuflo su rezistoriu, tai ims tuos 3A is batarkes, ir 10W bus LEDui, 13W grynos silumos ant balastinio rezistoriaus. Tai visiska nesamone. Impulsinis draiveris nekaista ir jam net nereikia jokiu radiatoriu...

I don't see any of these Chinese cells ever being able to drive the LED to it's optimum output. As a practical test with an XML-T6 LED, a 5 minute run with Ultrafire cells the light only gets warm. With the Sanyo it gets hot, obviously being able to drive the LED at full current for longer. In a silly sort of way I suppose ChinaFire cells would protect the LED from burning out if run on high for too long LOL. > > "Levas" <kazkur@pasbobute.com> wrote in message news:k9g68c$h78$1@trimpas.omnitel.net... >> 2.6A ir 6V tai 15.6W.
