Please check the links. What is the difference in these two drop-ins? They look almost identical yet one says 450 lumens and one says 1000 lumens. I know enough to doubt all claims and judge for myself. Just curious what the rest of you think?

LOL!

Actually it is quite correct. Both need a decent driver. :)
