This review is for the 1900 lumen model. These bulbs are significantly brighter than the Sylvania PAR38 90W bulbs that I replaced. In terms of dimensions, they are a few millimeters smaller both in diameter and length, but not so much that an ordinary person would notice when looking at light cans. These are spotlights and the light spread also seems to be a few degrees wider than the old PAR38s I've used. The only question is will they last as long as the previous product I installed. My Sylvanias have lasted almost 3 years and these HSs are claiming 2 years of life.
