I'm working on a project to sequence a number of red light strips into a jumpsuit, and I'm considering switching from my plan to use EL wire to instead use LED strips, spaced ~1cm apart. The current design has 17 channels, 22 segments.
My question is: how consistent are strips in terms of brightness and color? I will need 10-15 m of light so would use an port expander (NXP PCA9685?) with PWM driving MOSFETs, so I could calibrate for different brightnesses between LED strips, but want to make sure I'm getting the same wavelength.
There's no shortage of very inexpensive LED strips on EBay, any recommended vendors would be appreciated! DealExtreme has a lot of options too.
Any other suggestions on how to approach this?
