Led at stoddard

$190. or $350. is a bit pricey! What's the difference between the two as I read the description, I must have missed something?

Seems the 6 volt version is the reason

Those look exactly like the Vintagecarled.com lights/ assemblies, but a little more expensive.

i have been very happy with the vintage car LED lights I installed.

I have two sets of these which I purchased from Classico Steering Wheels for $279. I believe the same lights work for 6v and 12v, can do low and high beams. They fit into existing sealed beam light buckets, so they are truly plug and play for Porsche 356s. 

A few fellows tested them at the North Meets South Porsche 356 event in Cambria, CA just last month, and found that they didn't throw light as "deeply" as H4s in very did -- so visibility in rural places would likely not be as good. The Porsche 356 guys are after them because the draw is 20% less, and that is welcome news for an old electrical system.

Not sure what the difference is between the two sets they are selling at Stoddard. Further, the Vintage Car LED lights do look pretty much the same...

They claim they do not produce any heat ???

I think they do produce some heat, but not as much as a conventional bulb -- that is for sure. They do have fans on the ends, so they must be there for something. I think the amount of heat is negligible, however.
