I replaced all my lights on my 1977 h33 with LED lights from Bebi. I tried a few at first, and i liked them so much that i replaced everthing, including running lights (i haven't installed my new anchor light yet due to fear of heights).
They also had some really interesting strip lights, that i used to replace fluoroescetns in the galley and over the chart table.
I installed the lights inside the original fixtures, generally following the approach on their website (remove fixture, clean up, rip out old socket, solder Bebi light to switch and ground, then hot-melt glue the 'led bud' to the inside of the fixture). took about 15 minutes each.
They have cool and soft white. i put in mostly soft white which i like for active areas (galley / main cabin) and soft for vberth. (as a not, i had tried several other LED bulbs before settlign on Bebi, and i hated the spectrum - they were too green, and made people look pale and frankenstein-like). The spectrum of the bebi's is really decent, very natural.
btw, i measured the power on a few, and they were right around 0.1A. i have 11 lights inside, plus fore and aft running lights installed, for a total of 13. So i'm drawing less than 1.5A with everything on, only slightly more than the incandescent anchor light. (gotta get up there soon!)
So i'm thrilled with it, no longer worrying about power, and having better light.
