Rated 4 out of 5 by MichaelM Efficient, resulting in good value.
We have been relamping the parts of our facility that were converted to T-8 lamps a decade ago. These lamps qualify for rebates in our area, and we expect savings from the reduced power consumption and longer life to more than pay for the added cost. This holds despite the recent cost jump for these bulbs. We seem to have a somewhat high early failure rate though, possibly due to inappropriately adjusted occupancy sensors. The color seems quite a bit warmer than other 3500K lamps, but this may be only an apparent difference due to adjacency of cooler color lamps.
