2 sided leds and was dealing with dark spots. I don t have that with the 5-sided leds. They are comparable to the 35w hid systems (Same wattage as your J-specs). Not as bright as the aftermarket 55w hids I had but they would kill my battery if left on for anything longer then 5 min without the car running. Got sick of that really quick. Got my 5-sided from [ www.hidsrus.com ] they dont have them listed you will have to call them.
