greeting mga bro.. ihave a circuit design using 220volt ac, conected to 24 LED w/o using ac-dc converter...and it work na try ko na ..

i tried to make one of this DIY moonlight using an ac/dc adaptor, 6 pcs blue LED each has a 330 ohms resistor. I select 6v on my adaptor pero nung tinesting ko n, hndi equal ang npro2duce n lites ng mga LED. Ung pinakauna mlakas then pahina. Any idea bkit ganon? Thanks in advance s magrereply...(Newbies) 75gal Reef Tank

sir H5N1 naisip ko lang.. 
why don't you remove the resistor?
we tried using just the capacitor, ok naman..
may i ask kung anong power rating nito? and maybe we can use a transformer para medyo bumababa ang voltage kasi ang rami ng 25 LEDs.. or kaya na to ng icompesate ng cap?

ah ok.. gets..
sir question, have you ever tried using high powered LEDs as a light source? yung white? is it possible na gumawa nun na pwede i-compare ang output sa t5s?
pwede po parequest ng equation kung paano niyo nakuha yung current? salamat..
kamusta na po yung LED niyo?
