A filament lamp makes an excellent current limiter, for some applications, precisely because of its non-linear resistance, which is typically 10x its cold resistance when it's hot. If the lamp is rated at, for instance, 150 W at 220 V, it will pass 150/220 = 682 mA when hot, having a resistance of 220/0.682 = 323 ohms.
