How to make your 1940s halfpipers and shoplights more energy efficient « on: November 18, 2021, 03:04:53 AM » Author: WorldwideHIDCollectorUSA
If anybody really wants to learn how to make their 1940s halfpipers and shoplights more energy efficient, here is a video that you should watch: https://www.youtube.com/watch?v=FINlCkSR2w4 I posted this video because I find it funny when I read a funny quote about making 1940s halfpipers more energy efficient by recycling the big fat energy guzzling F40T12 tubes and replacing them with these adapters in conjunction with F28T5 tubes .

It really dont save much due auto transformer ballast here   Cause of voltage conversion  plus ballast loss,  then save it easy will be kinda insult as well.

If I am retrofitting a large installation of North American F40T12 preheat fixtures using autotransformer ballasts, the overall savings would add up.
