I didn't quite understand the listing. Selecting splitter type, the length of the EL strand is determined for you. Selecting 4-way split, the EL length is less because they are wired in parallel, max length of EACH strand is 2m. They work but I would have liked a longer strand, & I would have had to select fewer splits. Hope this helps others. Otherwise the USB inverter works ok & the color isn't as solid as the red EL from seller toymineinc. Good price.
