Review on Energy-efficient Halco 45071 Medium Compact Fluorescent: Powerful Illumination in a Compact Design by Mark Tarnowski

The only reason I'm not giving 5 stars is that the bulbs shown in the picture are not what you will receive, they are under the Halco brand, not Prolume lamps in the photo appear to be of good quality, but they are very different from Prolume. So if you need Prolume, you'll have to find another source. If they perform well, I'll gradually replace Prolume and move on to these.
