By the way this is one of the lights I've found that my mom loves: http://www.ballarddesigns.com/paxton-1-light-pendant/335736 I'm guessing the smaller pendants won't be bright enough for task lighting. Or do you think they'd be okay? The large one could be used over the table though.

Go with LEDs. They now have a range of color and can be ordered as warm white, similar to an incandescent. The incandescent bulbs will have limited availability and then disappear. From a Fox New article of 12/13/2013, incandescents are limited to stock on hand after 1/1/2014 "It’s lights out for the light bulb. On Jan. 1 [2014] it will become illegal to manufacture or import traditional 60-watt and 40-watt incandescent bulbs, thanks to a 2007 bill that set strict minimum efficiency standards – and effectively outlawed the ordinary bulb." A caveat: LED bulbs have short lives in totally enclosed fixtures. Heat greatly shortens the life of the LED. You may know LEDs work on 1.5 to 3V, so it needs circuitry to drop the house 120V to that voltage. LED bulbs styled to replace incandescents have the circuitry concealed in the base of the bulb. Both the circuit and the LED create heat. That 10 or 20 watts in a totally enclosed fixture can really raise the temp. LED dies in less than a year. This does NOT happen in table lamps with open shades because there is free air flow. It happens less in open cup fixtures that face either up or down. It does not happen in enclosed fixtures designed with integral LEDs because the circuitry is outside the glass enclosure.

A decent amount of work light is about 800 lumens minium. The Edison incandescent averages less than 350 lumens. The Edison LED isn't much better at 450 lumens. Great for lanterns or exposed bulb application. The Edison Vintage LED temperature is 2200 which is slightly above candle light. A typical A19 LED 60 W emits 800 lumens and it's dimmable. The A19 LED temperature is 2700. You're probably going to have to sacrifice "light" for "looks", or "looks" for "light".

Those are more on the yellow side of the LED color spectrum, so I think you'll be fine on the color. The difference between 2700K to 3000K will be almost imperceptible. 800 lumens isn't a geat deal of light unless it is for instance shining right into a bedroom at night, so it really depends how much the light is intefering into any other space, and that would include that of your neighbors' windows. Also a factor is whether you plan for these to be on all night or not. It's not too bright if you're turning them off for most of the night.
