I have 4 mags (a 2-D/two 3's, and a 4)...and they all have been upgraded to LED's...if you want several reliability options, trade your 2-D LED upgrade in for the 3-D (Same price), as the 3-D model makes the lost use of the Mag-Led (the most Lumens per hour, and better LED performance than the 2 and 4-D), and grab a Nite-Ize LED upgrade for the 2-D ($9) for a flood light, as I've heard the Nite-Ize C/D LED's are indestructible...or, you can try the Craftsman LED ($15) which will work in the 2/3/4/5 and 6-D Models!!! Like I said, this will give your variety with you maglite's and LED upgrades.
