So I don't feel like a lamp qualifies as 'electronics' but IDK a better place to ask about this.
Came across this Dazor model p-2134 drafting lamp and I remember my grandfather had one at his business when I was little so I grabbed it.
It was manufactured in the mid-1950's, and had been outdoors for who knows how long.. so needless to say the wiring and ballast were shot. TL;DR It's been torn down, cleaned, painted and I'm at the point of re-wiring and sourcing a ballast.
The original ballasts specs I am unable to find but the 'official' replacement is here, more details here on page 15.

Essentially it's a 15W, 120V, 2-wire magnetic ballast. I'm not super smart on fluorescent lighting so I wanted to ask, can you use a ballast that's rated slightly higher in wattage?
Like I'm looking at getting a compact electronic ballast versus the old magnetic replacement. I have a Robertson PSM226CQMVW that can handle dual bulbs (2 x T8) but the wattage is rated at 40w max. I want to assume that that means it's the upper limit but does not mean that it wouldn't comfortably handle lower wattages. But I figured I'd ask before I try it out.

Also a second question if I may; the original mag ballast was a two wire, input power and output power that daisy chained the two T8 bulbs. Do electronic ballasts work that way or do they require individual wires to each bulb?

OK Im reading how fluorescents are != to incandescents. So running a lower wattage bulb on a higher wattage ballast is usually a bad idea. Well crap, gonna have to buy a proper 15W ballast.
