Basking bulb shield

Are you asking if they need to be mounted in a bell shaped fixture? Then the answer is yes. The dome directs the light and heat downwards. If you mean some sort of wire cage around the bulb, then the answer is no.
I am still questioning why i would need a bell shaped basking bulbs shield if the temp at the basking perch is 95 deg without the shield. It appears the true better reptile basking bulbs have what appears to be a shield on the bulb itself.

Maybe @Alex and the Redfoot can explain this. It does have to do with the angles if I remember correctly.
The domes are more useful with "normal" shaped light bulb (eg A19). Something like what you're talking about or a floodlight that contains a reflector in the bulb don't need the domes so much.

The point of the housing/shade/reflector/bell is to use the light more efficiently. Without one, a significant portion of your light goes elsewhere from where you want it to go. That scattered light is wasted. Focused light is more effective.

For reflector bulbs (R/BR/PAR shapes), the dome does not influence the temperature at the basking zone because the bulb itself provides a well-directed beam. However, when viewed from the side, the transparent portion of the bulb is extremely bright. If the lamp is hung low, this bright spot will fall within the tortoise's field of vision unless the bulb is shielded by a dome.
