Review: High quality and very inexpensive. - These bulbs are a snap to install, and are switcheable between 'bright' and 'dim' if your panel allows it. Even the dim setting is plenty bright enough for recessed lighting and probably increased the longevity compared to the 'bright setting'. I got probably 18 months use out of them before about one-third of the bulbs blew. The rated life is 2000 hours, but I can say I got a lot more that that out of them. For under $1/per light, this is very affordable and the relatively long liftime should reduce the minor inconvenience of replacing them as needed. But don't misplace the spares. I tape my spares to the undersurface of the shelf that contains the recessed lights, so they are exactly where they need to be, when they are needed.
Review: Works great, evenly dimmable - Put these into a chinese-made bubble lamp, and they work great. Dimmer function works perfectly and evenly across the bulbs (which has been a problem with past bulbs).
