LED Replacement bulbs high moisture environment survival

I bought some cheap bulbs from sell at Yitamotor on eBay out of Washington as an experiment for my existing fixtures . That was 5 years ago and they all still work and have had no problems . 10 for $13.99 . They had both bright and soft white . I went with bright as my lenses have yellowed a bit after 50 years . Don’t see how more expensive one would serve me any better .
