Saw this post and thought I could give it a try. Waited 16 days and for under 20$ Canadian, received 4 sets of 5 LED's. Installation took less than an hour, including trimming the posts. By the way, these work well in the 6 reading lamps in the 348 (pair at bow, beside couch and aft-cabin). In total, replaced 19 lamps including the head and have 1 spare + all the old bulbs.

They appear yellow, and when lit, have a very slight yellow hue, but you would only notice if you did a side-by-side comparison.
Sorry for the less than stellar quality of the pictures below, as smart-phone photography of lights is challenging.
I do not sense any reduction in overall light output and I certainly can vouch for a significant reduction in heat (and thus power consumption).

Not sure why this blue tinge appears here (reflection of bedding perhaps), but the v-berth is plenty bright as well. A big benefit will be the energy saving when on the hook and "someone" forgets to turn the lights off!!
