Hi there,
I am wanting to make a lamp using the cold cathode lighting kits you use for computer case modding. I may want to have more than just the two that comes with the kit. They operate off of 12v...so say for example i want to run two pairs of these off of a 12v wallwart...what capacity(Ma) would i need the wallwart to be? How would i calculate this for two or more? Also is it possible to put these kind of lights on a dimmer and function correctly(ie. dim from off to full brightness)...if so how? and what would i require to do so?
Suggestions and help much appreciated.
the specs for the cathodes are as follows:
# Tube diameter: 3.0mm
# Tube length: 300mm/100mm
# Input voltage of inverter: 12v
# Output voltage of inverter: 680v
# Current draw: 5.0mAv
# Brightness: 28,000~30,000 cd/m?
# Lifetime: 30,000 hours
