The sample package lets you evaluate both dimming stabilizers for use in your applications or for deciding to stock for resale. There are (2) LDS-R resistive stabilizer and (2) LSD-E electronic stabilizer in a package. Sometimes one type works much better than the other. Sometimes two are needed in a circuit. All the different dimmer and LED driver interactions are very unpredictable so you must use test to determine which device works best.
