What you are looking for is called an Integrating Sphere. They are very very expensive, starting at like $2,000 for an absolute base model that is very small in diameter. You may be better off sending the lights to LSI or something to be tested, or become very good friends with someone that owns one.

Lumens is a measurement of total light output, and requires summing (integrating) intensities over a spherical surface. Not surprisingly, the instrument is called an integrating sphere. You can approximate an integrating sphere with a light box and light meter. Check out http://www.flashlightreviews.com/features/lightbox_output.htm for details.
