Lumen meters are a great way to measure white light output but can be deceptive for colored bulb intensity. Lumens measure light wavelengths in all colors of the visible spectrum. Because multiple wavelengths create white light and colored bulbs are a single-wavelength source, colored bulbs will have lower lumen readings. However, they will appear equally as bright as a white bulb. | ![]() |

Much Better
I originally bought a different bulb and it was no better than the old incandescent bulbs. I got these instead and they are so much better. I made a video, but it is too big to load here. I knock these 1 star only because the cost is so high for just one little bulb. But they do look and function much better.

Not plug and play
Tried to fit this globe into my 1968 Corvette (front blinker and parker) but globe wouldn't engage. I had to remove the light fitting from the vehicle and modify the base of the globe holder with a Dremmel so that lugs would properly engage. The globe holder is approximately 1mm too deep for the new LED. I hope I don't have this problem with the other external lights on the Vette.
