Well, having worked with such people, there are considerable variations within the groups.
When people think Amish they think people like in "Witness," but there are varying degrees of Amish, some almost resembling the Mennonites. There is no such thing as just "Amish" or "Mennonite." If Amish reject motor vehicles I've driven them home from work in a tress place in a minivan owned by a Mennonite. I've purchased things from e-Bay for an Amish who used LED lights and some smaller power tools. Then, just up the road from that Mennonite, is an Amish barn with cows, lit by...kerosene lanterns. yet one of them had one of those headband LED lamps.
