Longevity is still an unknown but these are at least comparable to the other bulbs. This is my second purchase and they have lasted with no burnouts.

These are very bright, compared to the old 40 watt incandescent. No more dim gloomy room. I suggest that amazon adds lumens to the filter list and allow specifc numbers rather than ranges.

Replaced regular bulbs in chandelier. Bought these for my daughter’s vanity setup.

Bought these to go into my volt deck lights. Work great, no flicker or other issues. I have 16 volt lighting brass deck lamps, for which these fit perfectly.

The flickering is bothersome. Standard’s bi-pin base includes super thin and flimsy wires that may not make solid contact with the fixture.
