Review on Upgraded LED Flashlight Bulb by Ruiandsion by Elizabeth Carey

I put it in my Mag Light. Well after sanding the lamp holder/reflector to mount that frustrating LED. Brightness wise it looked like a 200LM replacement in my other Mag bulbs and the beam failed to focus into one beam. It had beam blocks, not a focused spot. I was okay with that because it was directing traffic to smaller events. I was called to work on Christmas Eve in honor of the celebration and the first 15 minutes. everything worked fine. The mag light then cooled to 25 degrees Fahrenheit and began blinking. Then went to 0 lm, NO LIGHT., and didn't work at all. Changed the bulb to another brand and all is good. My idea is to stay away from flashlight corncob lamps. No recommendation but don't buy it. I made a return, everything went well with Revain, well. Then check out the estimated shipping cost back to China to ship the $17 bulbs back for only $127 to return the bulbs. I hope the estimate is wrong. Happy New Year 2021, may it keep getting better and better for you and your loved ones. Please don't buy this lightbulb, it reminds me of the bad moments of 2020.
