I haven't seen or heard of the ExoTerra linear UVB. Are you sure you're not talking about the Zilla one?
Edit: nm I see them in their site as reptiglo and mimicking ZooMeds 5.0/10.0 style. Honestly I don't know anyone that uses them so I couldn't tell you. They aren't recommended but they're not not recommended ya know? Hopefully someone chimes in with actual help in this matter. Ordering a bulb online shouldn't be too much of a hassle.
