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 .
