Is this bulb a UVB bulb?

I work with a pet store and this is the lamp we use for our dragons and we suspect it doesn't provide enough UVB for them. Some dragons have been seen by a vet and the vet says the dragons had no metabolic bone disease or calcium deficiency but we've had a few dragons have limb weakness, limb bending, and muscle twitching. If this bulb does not serve as a UVB, then I want to bring this up to the district manager and get the correct lights purchased.
