As an alternative to the pigtailed energy efficient lights, I called Cranes and went to a local electronics specialty shop and could not find any LED products. I am still waiting for products to emerge.

Crane quotes the highest output screw in LED assembly (not reflector type) as 60 lumens. (Lumens are a measure of light output). These are 2.5 watt power consumption at 120V.

A 100w incandescent soft light bulb runs about 1200 lumens. A 100w halogen is 1600 lumens. A 23w CCFL bulb has about 1500 lumens output.

So, if one is to duplicate the useful light output of a standard 100w incandescent bulb, it looks like you will need 20 LED assemblies to yield 1200 lumens. Or, to match a 23w CCFL bulb you will need 25 LED assemblies for 1500 lumens.

So, unless I am missing something here, these drop-in LED replacements don’t provide much light output.

There may be an issue with illumination angle, as the LEDs could provide focused light intensity for spot lighting, whilst the incandescents and CCFLs are omni directional.
