I've been looking to get white output H1 bulbs to match my HID retro. I also wanted a higher wattage since there for my Highs. I was going to get PIAAs but only have 55W-110Wouput. I ran into these and are relatively cheap. It also has a higher wattage 100W-150W output. Has anyone tried/used these bulbs before? I've also tried silverstars which seem to be popular amoung the HT crowd but they're not as white and have the same wattage as the PIAAs.
