I was @ local wallyworld today and they had Maglight factory 3W LED upgrades for $18.89. I thought it was a typo because they had 4D maglights hanging right next to the LED upgrades priced @ $18.00. I checked w/manager and she confirmed the price on the LED upgrade was correct. Are they nuts? Why buy a bulb for same price as the entire light? I don't think maglight is going to sell too many @ those prices.
