The standard lamp is becoming outmoded, and so too is the incandescent

The standard lamp is becoming outmoded, and so too is the incandescent light bulb, it is Edison’s miraculous invention to use so much more energy than the new low-wattage halogen bulbs.

The intended meaning of the sentence is that both standard lamp and incandescent light bulb are becoming outmoded.

(A) so too is the incandescent light bulb, it is Edison’s miraculous invention to use -
Two independent clauses, "The standard lamp is becoming outmoded, and so too is the incandescent light bulb" and "it is Edison’s miraculous invention ...." are wrongly connected by a comma. Two independent clauses must be separated by a conjunction instead. Incorrect.

(B) so too is the incandescent light bulb, Edison’s miraculous invention that uses - seems fine - Edison's miraculous invention ... modifies the light bulb correctly; also, that clause refers to light bulb correctly - hold

(C) so too the incandescent light bulb, Edison’s miraculous invention using - "is" - is missing after so too ...
Also, "using" without a helping verb is not a verb - hence, the comparison of usage of energy between light bulb and the new low-wattage halogen bulbs is not evident. Incorrect

(D) also the incandescent light bulb, it is Edison’s miraculous invention that uses - same issue of comma splice.

(E) also the incandescent light bulb, which is Edison’s miraculous invention to use - awkward sentence because of "to use" - incorrect.
