--- Quote from: james_s on January 22, 2023, 02:08:35 am ---I still don't understand why the tubes are wired such that the starter needs to be replaced. It would be trivial for a retrofit tube to have the pins on each end shorted together and take power from both ends of the tube, the way the type that is meant to use the original ballast are wired. Then simply remove the starter. Instead that video indicates they're using tubes that take power from only one end, the other end is just a shorting jumper and then you have to bypass the starter too. --- End quote --- If you took power from both ends of the tube in a traditional fitting with magnetic ballast, wouldn't that put the LED strip in series with the ballast? That might work if the LED strip was designed with that in mind, but then it might not work with electronic ballasts that have instant start. I imagine the designers have to cater for users who are not familiar with such details, and have to make things that uninformed users cannot screw up? |

Why should it matter if it happens to be an LED replacement instead of a normal tube replacement? |

It rather seems like Darwin award stuff, since sane people only hold the glass when installing a tube. Electricity is dangerous, you know? Touching exposed metal parts is not a good idea. But I get it, there is no accounting for people... :( |
