Hortilux bulb wattage

Where on the bulb is the wattage found? I bought a 1000w bulb w/out box and wanted to double-check the wattage before firing it up. I looked at the base of the bulb but didn't find the wattage anywhere. Wtf.

The bulb in question is approx 15.5 inches in length. The 600 watt is about 11.5 inches. I googled hortilux..
