The Arcadia 12% tubes are great for uvb bulbs, but I haven't had any experience with their basking bulb, and I haven't really heard of anyone using it either.
So i'd proceed with caution as it is seemingly untested unlike the three uvb bulbs we recommend here.
They do not bask directly under it, but they are within the range stated on the box. Their colours are beautiful already and they are acting healthier and more active than any other clutch I have cared for.
I am not saying this is down to the bulb, but I do believe it is of high quality.
