Today i retrofitted about 20 T12 fixtures over to T8.  (All had 1990 vintage Advance Mark III T12 ballasts)  I also installed 8 90 watt equivalant 2800k indoor LED Floods which increased the light output in that dark room quite nicely over the 65 watt incandescent floods they replaced.  I'd like to get some 3500k floods in there eventually, it will look nicer.    I also got me 2 60 watt replacement LED bulbs 3500k color, I really like the color.  Going to put one in the flush ceiling fixture above my shower.

We lit our new little 35W HPS lamp The wiring here is just a lash-up to see if the lamp worked, I'll make up a proper test/display board for it later. Edit 25/08/18 2205hrs - Board made up, photos to follow

It was actually yesterday that I did it, but I repaired the E40/E27 adaptor that we have and it's now in use with our 150W  Eye Color Arc MT150FSW MH lamp

James gave it to us last year, it originally had a 3-pin BC holder on it, but we didn't have a use for E40 to B22d-3 so I replaced the lampholder with an E27 one. Unfortunately, the wood that the holder was fitted to (I don't know what sort of wood it is, but it's as hard as nails if not more so  ) and it split when I tried to put screws into it, so yesterday Sammi repaired it and glued the E27 holder down with epoxy, so it's not going to come apart again any time soon

Ol RyGuy here has taken a side job that involves lighting.  I am working with a contractor and about 10 others right now and we are responsible for LED conversions at up to 40 schools as part of the Denver Public Schools system.  We are retrofitting from T8 to LED using GE LED tubes and GE LED Drivers(or ballasts if you want to call them)  We work from 4PM to 11:30PM.  We are working at a 1959 vintage multi-floor high school right now (Abraham Lincoln High School) and will be doing over 2300 fixtures in this school alone.  Today I was on a lift working on a bunch of 6 tube fixtures in the Gym.  My feet are going to fall off.  The contractor is going to let me take as many of the old T8 ballasts as I want.  Lots of Sylvania/Osram T8 ballasts so I will be quite happy.  When they retrofitted over to T8 from T12 many years ago, they initially went with the Sylvania Quicktronic 1st gen instant start electronic ballasts and surprisingly many of them have held up for 20+ years.  The ones that have been replaced have been done so with mostly the current gen of the Sylvania Quicktronic NEMA ballasts, which are the good ones, so I am super excited about being able to take a bunch of them.  I'll probably also take a good number of the good shape 4100k tubes- mixtures of mostly Sylvania, Philips, and a few GEs.  Photos to come.

@RyanF40T12: Why wouldn't they simply use retrofit tubes on the existing ballasts? Seems like that'd be allot cheaper/easier? Cool that you'll be able to get some of the old ballasts though!

using existing T8 ballasts for LED conversions is not a good idea in this situation given how old the ballasts are.  Most of these ballasts are the first gen Sylvania electronic instant start big bricks. (same size as the T12 magnetics) surprisingly they have held up quite well,considering they were installed back in the early to mid 90s and also there are still a good number of the pre-Ecologic T8 tubes that were installed at the time of the T12 to T8 retrofit!

Today I converted 21 fixtures over to LED in an elementary school.  I am keeping a bunch of low life F32T8 Sylvania and GE lamps as well as newer Sylvania F32T8 1, 2, 3, and 4 lamp ballasts.  I am quite happy about this.

Started replacing our dead led battens with better quality Saxby Hydron twins, in our main workshop at work. Also got some twin six foot fluorescent battens to re-tube tomorrow.
