Why pay pet stores 2 or 3 times as much? Go to a feed store, Tractor Supply, Home Depot, etc. & look for a "brooder lamp" & pay under $15. They come with a hook & a clamp (don't use the clamp). Pick the lamp with the ceramic bulb holder & make sure it handles the wattage of your CHE or bulbs.Pet stores sell ceramic lamp holders best if you use those for fire safety for your CHE and basking bulbs.
