One type is meant to work with the original ballast in place, and the other type you bypass the ballast and wire it straight to the line. --- End quote --- and the type were you need to replace or bypass the starter --- End quote --- BTW, the 'LED starter' is simply a fuse. And that fuse is a good idea in case the LED retrofit is suicidal. So far I had two retrofits go bang. |

The driver overheats, capacitors fail and the LED die ages super fast. You could say it's just a cost savings measure or planned obsolescence. But in any case, a LED bulb that should last well over 15 years lasts 2 years, maybe 5 years for a really good brand. --- End quote --- That's why some posters already suggested to go for 12V LED strips if feasible. Add a nice 12V LED SMPSU and you don't have to change retrofit bulbs regularly. |

However, I prefer subdued light for area lighting purposes, so I have all my area lights turned down on a dimmer switch and they will be running a lot cooler than full brightness. So I expect them to last a long time. |

Every screw in LED or CFL bulb I've torn down had either a fuse or a fusible resistor. |

Here is a google sheets doc for high CRI LED bulb options made by the flashlight enthusiasts at budget light forum. I've always wanted to try one of the Sunlike bulbs, I like the chunky heat sinking. Maybe it's a bit tooo how ya doin' for a light fixture but I bet it'll make for a great desk lamp or photography light. |
