Rated 5 out of 5 Perfect 50W PAR20 halogen replacement
I need to replace fourteen 50W PAR20 halogen bulbs in my kitchen track lights. I tried an excellent Sylvania LED bulb (Sylvania 78748), but at 3000K, it was too blue. It was also a little too bright and too focused.
I learned how to measure light bulb color temperature using the RAW setting on my Nikon D70, taking a picture of a calibrated white card, and then importing that into PhotoShop. In the PhotoShop RAW dialog, you just click on the white balance tool, and it reads out the color temperature. The halogens test at 2900K; the Sylvania LED bulb tests at 3150K; and this bulb tests at 2850K.
This bulb is a virtual match for the halogens, and when tested side-by-side with the existing halogen bulbs, it was indistinguishable in every way: same color; same intensity; same focus angle; and same, even illumination as the existing halogen bulbs.
The only thing I cannot comment on is longevity. I am going to purchase a few more and try them for a year.

Rated 4 out of 5 by mad1 Equivalent to Halogen in every way (except price)
These are fantastic replacements for Par20 halogens. They are the equivalent to halogens in lumens and significantly lower in power and lower in heat dissipation. The reduced heat dissipation is particularly noticeable in the warmer weather months.
