I threw away a few other types of lamps because they were wrong and looked bad. They have a smooth light pattern and look perfect. They are slightly longer than halogen bulbs, so your fixture may need modification. I measured them 4mm longer than the standard bulb they replaced which was fine in my case, now it touches the lens but it doesn't produce any noticeable heat.
