Morimoto is not cheap compared to ebay, ddm, vvme HID kits. Morimoto complete HID kits sell for $150. I assume the ballasts are $100 for the pair.
Their old style 3Five HID bulbs sold for $45, XB35 HID bulbs go for $50. TRS did a lumen comparison on HIDPlanet.com. Basically the Osram CBI HIDs are top of the line OE HID bulb, but they sell for $190 for two HID bulbs. The ouput of the XB35 HIDs are very comparable for 1/4 the cost.
Plus TRS has the best customer service. HID equipment comes with a five year warranty. Just email or call them with your issues you will have the replacement part in the mail the next day.l, no questions asked.
Nothing wrong with 5k, just a couple hundred less lumens than 4300k. Plus as the electrodes wear down within the HID bulb, they will begin to color shift towards the higher end of the kelvin scale.
I currently have a Kensun HID kit installed in the wife's F150 for over a year now and no issues. Not bad for $80 HID kit. If/when they fail, I will be getting a Morimoto HID kit unless Crees are an option by then.
