30w is actual draw though they do decrease as they heat up, down to about 25w or so. I used an old extension cord to wire them up so it had a plug already.
This is an example of when I was broke how I did it, although I used 8x13w mixed in with 2x40w LEDs. For a total of 155ish watts actual draw after the heat increase. Neighbors crappy mystery potting soil and fought mites late grow, it CAN be done lol...

These are the 30w shown on the link but the 6500k type...
