Thanks for all the original info. I used it in making my decision. I used to run stock with Silverstar ultras until I bought my wife a Lincoln Aviator. The HID's on the Aviator are absolutely amazing at night and I hated going back to my truck for night driving. I had already had to replace one of the stock Denali housings (deer!), so I had one original housing and one Depo.
I went with the 55w Innovited kit on Amazon. 5000K. The color is so much better and the output is better than Silverstars IMO. However, I noticed that my original housing wasn;t nearly as bright as the Depo housing. I got a new HID bulb to check , but it turned out that the OEM housing was just old and dirty. I read about taking the projector housing apart and cleaning it and said - nope - so I ordered another Depo.
So, 2 Depo Denlai projector housings and the Innovited retrofit kit. I love the color. Theo output is good, but as has been mentioned, the beam spread isn't optimal. To me it seems aimed too low, so your bright spots are closer to the truck than you'd want. I also did the 4 HI mod and I like that since I drive country highway every night.
If I had it to do again, I still would. I like them over the stock setup and so far haven't had any problems. I added a set of LED fogs at 500K to get the front matched. I'll try to get a goot output shot or two and post them.
