Okay, so i'm about ready to start putting this little project together...i decided to go with three sets of the cold cathodes, each with an on/off switch. What rating of power would i need for the power adapter...also does this cause a problem if say only one set of the lights are on...while the others off...would it be receiving too much power or would it just draw what it needs??
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
