CC tubes and intenisty

post #1 of 3
Thread Starter 
I recently got a cold cathode tube ( Logysys 15' white color )

But i have a problem, ( beside lack of tools and materials for modding )))
It is so dam bright, any LED Lights are just nothing compare to iy , and i do not want to compleatly get read of them ( I got a few there, CPU fan, getho HHD fan ( i'll try to make picture of that one ) , case wall and fans and more on a front... ) All of em are compleatly nothing when i turn on 1 tube... So


Question is...

IS THERE ANY WAY TO MAKE IT A LITLE BIT LESS BRIGHT ???

Thanks in advance and walk tall everyone !

Cold cathodes rely heavily on the length of the cable becuase of the extreme voltage it runs on. To make the light less intense you can increase the length of the wires double the length and it makes it half as bright and so on. I would recomend you make it only about half of the original length of the wire longer. For example if the original cable was 12 inches then add 6 inches more.

Hope this helps,

Ken

Hmmm ok i aint that great at Physics... so i hope alcohol didnt washed all my "knowledge"... Is the formula I=V/R correct?
I hope so ) so V = I * R so Since there is no way (simple one, or at least as i remeber) to change a current... increase resistence? Hmmm may be i should just get a ressistor cut one wire and put it in a middle??? Which wire btw? Black or Red? Any help dudes?)))
P.S. Ty mate for help, you did help by just replaying) I had hard time getting any replys around hear...)

Walk Tall everyone ))).....
