Sylvania 20672 Compact Fluorescent 18 Watt: Energy-efficient Lighting Solution Review

I'm having trouble finding Panasonic FDS18E35/4 4 pin light bulbs to replace the ones that have burned out in my Panasonic bathroom fan. Sylvania 20672 worked great. It starts up instantly with no flickering, and I like the 3500-degree color temperature - not too yellow (2700 degrees) and not too blue (5000 degrees). It's the color of a bright and sunny morning.

Sometimes it's hard to find 4 pin versions in a big store. When you find them you're usually limited to 2700k, which is a yellowish light output. Or you can find 4100k with bluish light output. This 3500k is exactly the color I prefer, in the middle of two extremes. Combine that with a great price and fast shipping and you can't go wrong.

They are a perfect match for our Panasonic fan/fan/heater for bathroom. I'm talking about two of these bulbs, but I only use one as it's the perfect brightness for when you're going to the bathroom in the middle of the night, but still not too bright to fully wake you up. I've ordered a few and keep them in my bathroom drawer for later, but I'm too lazy.
