If anyone needs a lux or footcandle meter and doesn't want to buy their own, try the industrial hygiene or safety department at your employer or other company you may have a relationship with. They need them for determining proper lighting levels in workplaces and proper outdoor nightime illumination levels for employee safety. Most meters are just sitting around unused 99.9% of the time so you probably would have free reign to use one for a few days at a time.
As I learned from quickbeam at flashlightreviews.com, the square root of the lux reading at 1 meter provides the distance in meters (throw) at which the light will illuminate a subject with 1 lux of light, so this is a very helpful number to have.
Also, access to a light meter means you can construct your own shoebox or milkcarton lightbox (QUPS) for measuring total light output. Also a great number to have.
BTW if you get a footcandle meter and want to convert the value to LUX, just multiply your result by 10.76.
