My research indicates that 1 lumen = 1 cd.
To help with your future evaluation of these numbers:
a lumen is a measure of _total_ light flux, a candela is a measure of light _intensity_ in a particular direction.
If you look at a light source from different directions, it will appear brighter or dimmer depending upon its directional characteristics. The brightest point gives you the cd measurement.
Note that a very well focused light source could have a very high cd measurement, even if it doesn't put out much total light.
You can make an analogy to linear measurements. Light flux is to light intensity as volume is to height. Consider a mountain.
The peak of the mountain is so many meters high. The volume of the mountain is so many cubic meters. You can have a 'mountain' that is short but very wide, having a large volume, or one that is very tall but quite narrow, having less volume.
The exact relationship is that 1 cd is a light intensity that results in 1 lumen per steradian. To go back to the linear measure analogy, this is like saying that 1 meter is the height that produces a volume of 1 cubic meter per square meter. There are about 12.6 steradians in a sphere, so a perfectly even 1 cd source would put out about 12.6 lumen.
