Suitable for all types of models, this set contains 60cm (approximately 2 feet) of super-small LEDs (36 total) with integral resistors on a flexible, self-adhesive 'tape'. Suitable for 6 to 12 volts, DC. LEDs are extremely bright when operated at 12 volts; brightness can be changed by using different voltages. Tape may be cut at 50mm (2 inch) increments. Integrated 3M pressure sensitive adhesive makes attaching it nearly any model quick and simple.
