2009 400W HPS M-400 Installed On the Tapered Arm
|
This M-400 originally came from Providence, removed in 2016 during their LED conversion. I bought it on Craigslist for $30. It's 400W HPS and was installed my NGrid in 2009. Many were on tapered arms just like this.
This one has a 400W MV lamp in it. I pulled out the plug-in ignitor to allow MV lamps to be used.
