EYE HR50W Got a pair of these from eBay. These are pretty interesting as they have a diffusing coating instead of a phosphor like most reflector MV lamps. No doubt for landscape lighting where the greenish look of unfiltered MV highlights foliage. Interestingly these are rated at a slightly lower lumen output compared to the R20 version. These have "20D" date codes on them, I'm guessing April 2020...months before EYE stopped making MV lamps. Keywords: Lamps

That date code is correct.

It looks like quite a few of those nice little lamps found their way into collector's hands.

@Ria - Thanks, these are my newest MV lamps and the only two I have that are from the 2020s.

@Max - Agreed. The eBay seller I bought it from was a lighting company so maybe they are clearing out old stock.
