Lithonia Wraparound
|
Here's a replacement wraparound I got to replace the old one in my room that had a broken diffuser. It came with a cheap Accu-Pro ballast so I removed it and put the custom ballast setup from my old wraparound back in.
The ballasts are a Sylvania 2 lamp IS wired for one lamp and a Sylvania/Motorola electronic RS ballast. Unlike the newer electronic RS ballasts that starts the lamp instantly, this one has a bit of startup flicker.
Sockets were Levitons salvaged from the old light and lamps are Philips natural sunshine 5000K T8s.

As for custom ballast setups, what was the idea here? Unique startup/if one ballast dies the other lamp stays lit?
Right now I have a 400w multitap MH ballast running a 277v Advance single-lamp T8 ballast off the 277v tap (it's wired to 120v like normal and just acting as a step-up transformer) running a spent GE Chroma 50 that's REALLY black at both ends. I bet it sat EOL dim-glowing on magnetic rapid start for many months or even years to be this black! It's gone like this for a couple weeks now...and seems to be hanging in there!
I guess you could use two single-lamp magnetic rapid start ballasts or two 2-lamp ones shunted for one lamp...
