The lightning optical signals were measured by a silicon photodiode detector(PDD) at Conghua city Guangdong province and Changping district Beijing city in summer, 2008. Totally, 12 observed data were analyzed statistically. The maximum optical peak magnitude is ［10.97(5.55)±12.46］ mW/cm2, the 10%-90% pulse rise time is 1.14(0.44)±2.02 ms, the 50%-50% pulse-width is ［1.44(0.49)±2.07］ ms and the single lightning optical peak count is 3.78(3.00)±2.30. The radiance peak is one to two orders of magnitude more and the pulse-width is broader, compared with the FORTE’s PDD data. These results are reasonable according to the lightning radiance mechanism and physical evolution process.
