Hi!

again my LED-Cluster-Project.
ill use between 50 and 100 LEDs, maximum 10 watts.
i hope to be able to use 2x4 NIMH cells, but perhaps just 4 will fit. these 2300mAh Ansmann cells can deliver up to 4.6A maximum.
my question is now, how "fast" will they give me high currents? if i use a PWM, it would try to get 1.5A or 3A in fractions of a second. im quite sure thats way too fast.

did anyone try something similar yet? perhaps PWM and a LS?

if it doesnt work, i could use a huge capacitor between PWM and cells. but would be large and dangerous, with that huge energy stored.. would prefer to avoid that..

any hints?

thanks
