Light meters can also be highly variable (i.e., I've seen up ~40% difference between inexpensive meters). All of my measures are done on a NIST-certified, calibrated lux light meter.
Finally, there will also be some variation between samples. Also what kind of batteries used, how charged they, how long after activation (ANSI FL-1 requires 30 secs, which mine are done at), etc.
Two meters is not enough. ANSI FL-1 standard requires 10 meters for a light this size, which is what I do all of my testing in. This likely explains most of the discrepancy with your result.i measured it from two meters. i measured in ft-cd, i convert it in candela after and that was the results.
