Rated 5 out of 5 by MikeT Great for crafts
We replaced some older halogen bulbs that came with my wife's craft light that she uses for needlework. These bulbs are much whiter, cooler and use much less power. No more yellowi cast and heat. Her needlework hobby is much easier with improved lighting.

Rated 2 out of 5 by Larry2919 Too many defective bulbs
These bulbs have a reasonable color spectrum (which is why I ordered them) but too large a percentage are defective and burn out during the first hour of use. In one order of ten bulbs, there were two defective. A subsequent order of eight more bulbs yielded one defective (so far--not all have been used yet). I'd buy another brand but these are the only R20 3500K bulbs I could find. Recommended only if you need this size and color temperature.
