The second LED bulb put into service in the office is now out of service. That it gave little light was brought home by the fact that we didn't really notice just when it went out. Jay was surprised when he happened to glance at the light fixture. It wasn't a loose bulb, either. The base has that peculiar "electronics that got too hot" smell to it. We both suspect the current limiter burned out.
I did save the original package and the receipt, so we will now see how good the manufacturer's two year warranty is. The light didn't even make it a month. The other LED bulb is still going.
Meanwhile, the room is a little brighter and a little yellower (or less blue) as I've put one of the older CFLs back into service.
