Does anyone make a wired and dash mounted map light for the car with
several luxeon LED's in it? Something that puts out some really
significant lumens, for example 200 lumens?

A lumen is equal to 1 foot-foot candle falling over a 1 square foot area.
FYI, a typical office is 50 to 100 foot candles, so I would think that the
glare from 200 lumens would make your night vision so bad that it would take
20 minutes to be able to see in the dark again. I would imagine that 25 to
50 lumens would be more than enough to read by.

Here is a commercial quality hard wired map light:

jcwhitney.com also has map lights

Could someone please address my original question, without tangents?

Probably, though I'm sure they wanted to try to advise on the rather
over-kill nature of the original request in order to save you money and
trouble at a later date.

I really wouldn't get hung up on the Luxeon name. Luxeon is just one
brand of high-power LED (out of three or four) that has happens to have
good marketing to the end user.

Talking of which... Have any of the cheap Chinese copies been showing
failure characteristics?
