well guys personally I would stay far away from the Winjets, they are very much like the cheaper $40-50 ones you can buy on ebay. I made an album and wrote some general notes about them, which you can find here.

I've owned these for about a month and one already cracked (the crap ebay ones seemed to have thicker glass and lasted for years without shattering, go figure!!! ). More importantly IMO they definitely aren't IP66 or IP67 rated as moisture has no trouble getting inside the lamp fixture, which will definitely rust and kill the electrical connections to the bulbs! That's how my cheaper $50 ones went bad. In spite of not being able to use them they were still nice because the glass didn't shatter.

Personally I wouldn't touch these if they had a 5 year warranty, too many sloppy design decisions that are definitely going to lead to problems/breakage; just look at that other guy that posted here who's on his 3rd set due to shattering lens/glass.
