Are those hids on the ls or just brighter halogens? I get the part about the coating, there are stage1 bulbs that are stock replacements that are 55 watts, then stage 2 are high output halogen upgrade bulbs and are 80 watts. I have the 80 watts, I would atleast think it would light the same as stock 55 watts with the coating on it being 80watts but not less.
