D'Addario ECG23 Chromes Flatwound Electric Guitar strings, gauges 10-48. These are in extra light, have warm, mellow tones and a smooth silky feel, with almost no finger noise.
The 4 bottom strings are wound with a flat ribbon (rather than the usual round wire), which is then polished to make it even smoother. Great for that classic jazz tone or rockabilly twang. The thicknesses are 10, 14, 20w, 28, 38, 48.
