You don't want a regular household bulb because the
brand/size
printing on the end of the bulb can/will become a part of
your print.
My 1C calls for an Opal 75 watt. So, I guess the 211 is
what you want.

Beside having the branding on the side of the neck
enlarger lamps also have a much more diffusing coating on
the bulb. They are called opal lamps because the lamp glass
is similar to opal glass. Standard reading lamps will cause
a hot spot. The type PH-211 is used in a lot of enlargers so
its available but, as has been pointed out the price may be
high. I don't know of a way of duplicating the coating but
there may well be one.
