Recently, my Surefire Lumamax LX2 has begun strobing on the low output setting and I can't figure out why. Im in Europe right now and my light has been packed in my bag and I took it out to use in my hostel and it started strobing. It worked a few days before just ine and the high outputs woks fine as well. Anyone ever have this poblem and know how to fix it. I appreciate it.
