35. Yeah the chart doesn't say but the math works out for a 60 watt bulb (and 13 watt CFL).
Average US electrical grid mercury emissions is 0.012 mg per kWh.
The bulb on right emits 5.8mg thus it is 5.8mg / 0.012 mg per kWh = 483.3 kWh.
Chart is for 8,000 hours so 483.3 kWh / 8000 h = 60w.

The left
1.2 mg / 0.12mg per kWh = 100 kWh / 8000 h = 12.5w
