About 7 to 25 *watts* looking like a misprint: There are laser diodes in the watt range, however they have very short, pulsed beams, unlike the continuous output types usually found in CD players and the like. As the posted specs said, these have a threshold current of 1 amp, and some kind of peak current of 8 amps: they are powered by a high current pulse. (Trying to lengthen the pulse beyond the few microseconds recommended by the manufacturer would probably cause the diode to overheat.) ***********no signature; my name's at the top^************
