Rated 4.8 out of 5 by 12 reviewers.
Rated 5.0 out of 5.0 by Bright Lights - This product is worth the price Typically, we have a hard time finding a good price on the 96" bulbs. I search far and wide for these bulbs, but wanted a local source because I did not want them damaged in transit. I had never tried the brand before, but must say they are an excellent replacement bulb. They seem much brighter than the old bulbs. I cannot say enough great things about these bulbs. Have not owned them long enough to determine their life capacity. April 8, 2014
