This is a pack of two of our warm white LED Light Strips that also includes two 6" connecting cables.These LED Light Strips will bring any project to life Use them in any LEGO® project, on any model railroad layout of any scale, in Department 56® or Lemax buildings, in dollhouses, or in any robotics project to add detail and interest and capture that “wow” factor. No electronics or soldering knowledge is necessary to set up these lights and start using them right away. Use the adhesive backing to easily mount the strips to almost any surface—put them anywhere in even the smallest structures. The strips are flexible, allowing you to mount them even on curved surfaces. Connectors on each end of each light strip allow for multiple strips to be connected end to end—connect 100 strips or more to add light to even the largest model project. Unlike other light strips that use 12V or 24V, these use 5V and are ready to use with any microcontroller or robotics project—no need for complicated resistor calculations The strips produce almost no heat, allowing for installation in the smallest spaces. Typically, nine of these Light Strips are needed to light a standard LEGO® Modular Building. NOTE: This is two individual Light Strips with 6" connecting cables. No power source is included, but these can be purchased separately.  To use the Light Strip, you will need to purchase a power source.
