These people have been selling lots of 15 or so green MR16 bulbs for cheap. I’ve bought three lots at the opening bid price ($9.99)… only bidder. They say they are 192 lumens… but that is a lie. I measured 300 lumens! They are obnoxiously bright. They totally drown out a 330 lumen white bulb next to it. They also have had amber bulbs. I have not seen any red ones.
I was going to use them in my rocket launch tower beacon, but they arrived after the guy that was building it had built it… 3000 Lumen Rocket Launch Tower Beacon
