That's for the left-side-traffic version, which means it's a UN lamp. Not a very high-performing one...if you look at Table 8, you see a maximum measured value of 22.17 lux somewhere unspecified in Zone 1 (1.72° to to 4° Down, 9° Left to 9° Right). That's 13,856 candela.
At point 75R (0.57° Down, 1.15° Right) there's 12.31 lux, that is barely above the minimum requirement of 12 lux, and equivalent to 7500 candela. [nearest US requirement is at least 16 lux / 10,000 candela at 0.6° Down, 1.3° Right]
At point 50R (0.86° Down, 1.72° Right) it gives 19.34 lux, that is 12,088 candela.
At point 50V (0.86° Down, straight ahead) it gives 13.05 lux, that is 8156 candela.
It would be interesting to see photometry for the US version of this lamp, but I wouldn't expect it to be a whole lot different or better, just with some of the light distributed differently to meet the different test points and intensity values. This lamp was a "first", not a "best". Everything about it was still in its infancy, relatively speaking -- the LEDs, the optics, the cooling, etc.
