thank you so much

guys to which wire do we connect a switch? the positive or negative? i have the resistors connected to the positive... please let me know ... thanx

i understand, ok so i have blue and white leds , both of the same specs only the colours differ, does white require more power to burn than blue?

which would be better to connect? i have 13 leds to connect across a 12v supply would it be best to connect them in series or parellel? i read that parellel allows you to add more leds on a single voltage like if you have 3 leds of same spec each requires 3v each and you have a 3v power supply...

would connecting let's say 4 leds in series with a 3v each led rating to a 12v power supply work? as the 4 led with 3v each gives you = 12v would this work without the use of a resistor? http://www.theledlight.com/ledcircuits.html ive seen this site and it shows it can be done, is this...

hi guys, thanks for the advise and help, ok so i understand that if the tube is a higer wattage rating than the ballast it would work but its a waste in cost, the reason i asked this is should there not be any florecent tubes that is matched to my ballast that my local supplier has then i could...

thanx bolts thanx guys, i will continue with my circuit

like this ?

hi guys tell me something i have seen electronic ballasts for florecent tubes, they come in different wattages as well as the florecent tubes, what i need to know is the following... 1. if i get an electronic ballast that states 15watts and buy a florecent tube that is 20watts would...

ok i do understand that sha_virgo as mentioned you said connect in series, i have posted an attachment as a sample of what i am speaking off, so would i be correct in doing this as illustrated by my diagram? would this be the correct connection ?

thanx so much, so would i connect it as such all 12 of the led with resistors?, see my attachment ;)

hi everyone, I am new to this forum, hope I am posting a thread in the right place, if not could any MOD please place my thread correctly... thanx guys i need to know how to connect my resistor to a LED i have 12 white leds 5mm that is 3.6v each @ 30mA im using a 12V power supply for...
