Hi all. Just bought what was supposed to be 0light m20 s r5. It has 320 lumens for 4 hrs. When I got the light the box said it was the wp-g2 which has 420 lumens but only lasts 1.5 hrs. Then there is an extra sticker on the box which says 320 lumens The barcode that comes with is covered over by a sticker. I removed it and checked the barcode and it doesn't register. The manual inside is for the xpg2 also. So how do I know what I really got? I researched quite a bit and decided I wanted the r5 because of the 4 Run time and many people said the extra light wasn't that much. Now I don't k ow what I got. Is there a way to tell which led is there. I did email the vendor they amazon but I can't even tell if the email went as every Tim I hit send it just reappears as if it didn't go. I may have sent the question 4 times or not at all. Any ideas for me?
