The approach you suggested will definitely work. In the old days of film I used that technique with a view camera. It requires two lighting setups (turn on one, make the "product" shot, turn those lights off, turn on the second set of lights, switch to lith film and make the second shot, Sturdy tripod. Remote shutter release.Today it can be done digitally. Decent distance -- perhaps six feet -- from product to background. Umbrellas bouncing light on background and shielded from the product in a darkened room will work for the "silo" shot. Curves will enhance contrast, if necessary. Photoshop's auto align will be a great help in registering the two images. But you are talking about 10,000 bulbs. Wow! One suggestion: it would be wise to light & shoot the product shot first in the event you may want to use dulling spray (which is removable) in prep of making the silo shot so you don't pick up stray reflections. The more care in camera, the less you need to do in Photoshop. Running a test with a dozen products would be a prudent move. Then, when the lights have be set as perfectly as possible secure the room in which you have the set.
