ultrajamie Posted January 6, 2007 Share Posted January 6, 2007 I've a slightly obtuse question about led's I've just hooked up one of these: http://cgi.ebay.co.uk/BRAND-NEW-BLUE-3-LED-BEAM-KIT-IN-CHROME_W0QQitemZ140070219581QQihZ004QQcategoryZ75520QQrdZ1QQcmdZViewItem#ebayphotohosting to a 500ma 12v dc transformer... to use on my aquarium so i can see my catfish at night. Anyway, i've got the transformer set to 7.5volts because 12v is too bright... anyway, the 3 leds in the array are wired in series, but i want to hook up another set at the other end of my tank... can i do this by wiring them to the same adaptor - if effect creating two parallel circuits of 3 leds in series... or should i wire them to another adaptor? thanks in advance for your help Link to comment Share on other sites More sharing options...
Guest Stefkov Posted January 6, 2007 Share Posted January 6, 2007 I think you coudl do that, but you'd have to have more power going through the circuit. So maybe up the power from the transformer. If I remember, if you were to have the 3 other leds coming off it in parralell, then that would take half the power going to the one in place. So it would half and half it. So I think it would work if you just attached another one to it. I hope that I've remmebered something from those 2 years of Electronics, lol. That looks pretty nice, but you could have made your own. From maplins, maybe. I've not been to Maplins in ages though so i cant remember prices.
