Rated 5 out of 5 by john23 Bright per watt - similar to 15 watt
I have a house with 4100K Neolites on the 1st floor, and 5000K Neolites in the basement. The 4100K turn on to full (well, probably "nearly full") brightness instantly, but the 5000K bulbs take some time to get there. Color is good, and they are small which is great.
