In your various Industrial Pendant Lights, they all show your Edison vintage bulbs which you carry many shapes, sizes and lengths. Is it possible to advise which bulbs to buy to have the same look in your product pictures? All the cones we're looking at are the 4, 3, and possibly the single sconce, but all have the open ended cage so bulb length doesn't seem critical as with the other designs you have that use closed cages. Thanks!
