i dont know much about them, other than the fact that they look fantastic!!! saw comparison photos of super bright (bluish tint) white led’s, incandesent, and golden-white led’s in some HO engines…the golden-white led’s are the answer to everyones prayers for a realistically looking white led!!! :^) :^) :^) anybody have any additional info such as price, sizes, and availability??? thanks for any info someone may shed on this…
