All mercury vapor bulbs will put out more UVB than a 10.0 UVB bulb. Most MVBs put out between 25-75 units of MVB depending on the brand and rating of the individual bulbs, the distance above the basking area and age of the bulb. The tubes rated for 10.0 only put out 10.0 units. (again, it various a bit on distance from bulb and age of bulb)

There are a couple sites that show ratings for various bulbs. If you check out Dreamworks's post a couple threads down, he gives a reading of his bulb and the sun with his own UVB meter.
