Current limiting resistor calculator for Led's

[sunny03]

here the web site of it for those interested to find out the resistor for diy their own moon light website

its led. how do i know its really having moonlight ray from it. the sample is red color led

[sunny03]

most ppl using blue led as for the benifit there a lot of arugument about it.. some said that the cycle of the led ( which need it be dim follow the moon phase cycle )

[ben]

but what power rating should we have on this led in order to get the blue moon effect?

[sunny03]

heard that have to get a dimmer to adjust the brightness of the moonlight

just like in some of the night we have full moon and no moon all that
