The system I have experience with is the Denalis from Twisted Throttle. Twisted Throttle has no mercy on price, but offers a very complete and tidy kit with a variety of mounting solutions. They are melt-your-face-off bright, and come with a selection of lenses to tailor the beams to your taste, including an EU compliant beam pattern. I've also looked at the lights from Trailtech, http://www.trailtech.net/lights.html. They offer a number of lights and mounting solutions. I particularly like that their LED features a three-level intensity button on the housing. They are a bit friendlier than the Denalis price wise. If you search under parts, Trailtech has a quite number of frame mounts that are well-priced. Their "lick-em-and stick-em" glue plate mounts look versatile. I'd want the mounting surface to be sparkling clean, though. Both are 6000 - 6300 degree Kelvin color temperature, which is a useful range. Lights that are of a higher color temp tend to be too blue, and aren't as good. Intense blue light tends to piss off oncoming motorists, in my experience. Sunlight is about 5500K, as a reference. Rigid Industries www.http://rigidindustries.com makes many LED styles, along with a great deal of mounting hardware. I have no experience with their products on bikes, but have seen them on other off-road vehicles, and they appear to be solidly built and up to the task. The LED clamp system, here: http://www.rigidindustries.com/product-p/rgdlldclmp.htm features many clamp sizes. Adventure Motorcycle Parts has some bar mounts in 7/8", 1 1/8", and 1 1/4" that look well-made. http://www.adventuremotorcycleparts.com IMHO, the cheapo WalMart/Ebay/Discount Auto Outfitters LEDs aren't worth the time and hassle to install. It's not simply an issue of making light, but projecting it in a useful manner. If I'm going through the expense and effort, I want something that works as it should and more importantly won't fail when I really need it.
