Satco S6273 18-Watt Medium Base T2 Mini Spiral, 5000K, 120V, Equivalent to 75-Watt Incandescent Lamp for Enclosed Fixtures, 3-Pack

Works very well as a cost-effective replacement for standard A19 bulbs in our indoor lights -- the mini spiral means it's not as tall as the usual CFL bulbs and can fit under most lampshades and fixtures properly. One thing to note is that these bulbs when turned on will start at around half brightness, then grows to their maximum brightness over a couple minutes. I chose the 4100K bulbs to replicate an "indirect daylight" level of white lighting for our dark [first floor] apartment. Have had them for 8 months so far and they've worked great. Nice level of white light, good for reading, watching TV, etc.

I had an energy efficient bulb in a lamp in my living room but it didn't give enough brightness. Both my wife and I are in our early seventies and don't see as well as we did in past years and your product is just what was needed. Thank you.

Perfect Daylight White lighting for my garage for when I clean my car. Big difference switching from 1600 to 5000.I like these so much I bought 2 more to replace the bulbs in my basement bar.

It works satisfactorily, but not so "mini" as you may think.

These have a short life in a ceiling fan. Perhaps they function better in a lamp?

Excellent! Perfect the the kitchen!

I love these bulbs for my outdoor home fixtures. They are bright and getting them in the 5000k range makes them even brighter than a warm tone bulb.They light up my property very nicely.
