Now comes a new set of products by manufacturers that have already proven to us that they can provide LED downlights with the brightness to replace incandescent.

The new tiny, screw-in, reflector lamps (bulbs) are designed to replace energy hogging PAR lamps and MR 16 lamps. They provide light levels that are on a par with halogens up to 120 watts, and the light is focused much tighter than an LED downlight.
For further information on these new gems in energy efficient lighting see
LED Retrofit Lamps Now Viable as PAR Halogen and R-Lamp Replacements, by Kevin Willmorth, on page 58 in the July/August edition of Architectural Products Magazine.
There you will find information on the brands tested and approved (GE & CREE), and caveats: Not dimmable, no energy credits (because they can be swapped for incandescent).
