led strips

Can you give me the details of constant current led strip and constant voltage strip ?

Which is most suitable for the decorative lighting ? :o

constant current led strip and constant voltage strip

Constant current and constant voltage are the two ways of controlling the current flow through an LED. When the LED power is large then you need constant current to ensure a safe stable power supply. If the current is low you can use constant voltage and have a current limiting resistor in line with the LED.

I am about as unsure of what you are actually asking as you are. What are you expecting a list of things you can buy? Is the decorative lighting to see directly, like Christmas tree lights or to illuminate a space? As this is an arduino forum what are you hoping to do with the arduino?
