Driving tons of small incandescent light bulbs

[jimon]

So, let's say I have 72 light bulbs like this https://www.grainger.com/product/GE-LIGHTING-Miniature-Lamp-6VF02 they are 5w 28v little monsters and I want to drive them digitally. There will be max 18 bulbs turned on simultaneously, and 6 turned on bulbs will be an average load. (PS. if anyone knows bulbs with smaller working voltage in #313 case - I'm listening)

There is primer for driving them : http://www.allegromicro.com/~/media/Files/Technical-Documents/an295012-A-Primer-On-Driving-Incandescent-Lamps.ashx?la=en which basically says using current limiting resistor or warming up resistor, or just use current limiting driver and be done with it.

So can I just use LED driver IC's and be done with it? Though I would like to avoid any PWM stuff if possible, to make it more "vintage" of sorts ..
Or what would be the best way to drive them for one-off device? Cost doesn't matter much.

0402 would be quite a challenge I more looking for something that can provide multiple channels in one package ... otherwise indeed mosfet+resistor per channel is "a way to go"

Hm, so I guess instead of just #313 bulbs I can get any BA9s T3.25 bulbs ... which enables me to get 5v or even 2v bulbs!
Than something like this http://www.ti.com/product/tlc59116-q1 which is 16 ch LED driver start to make sense! I can cover 72 bulbs with only 5 IC's!
