Hey, I am going to purchase a light tonight, this will be my first Fenix light. Currently I have a Coleman LED light I carry, but am wanting to upgrade. Are both of these lights close to the same? Is one newer than the other? I was looking on Amazon and the LD10 is $7 dollars more .. Was wondering what the difference is between the 2 lights? The L1D is 48.00 .. Just wondering which would be a better deal ... Can someone please help? Thanks!
