I converted this GE M-400A3 into a growlight as the slipfitter was damaged and cannot be mounted on an arm.
Manufacture date: Apr. 2004
Manufactured in: USA
Voltage: 120/208/240/277V
The PL growlights are 400W, and the GE M-250R2 growlight was originally 400 as well,but I needed a 400W ballast in one of the PL models,so I removed it from the GE and installed a 250W in the GE instead as it's mounted lower along the side bench of the greenhouse closer to the plants.
Cool conversion, I remember this pic of your green house Darren, and the famous 8 ft strips too. The GE M-400A3 looks pretty nice as a grow light even in my opinion, better looking than most of the pre built ones out there.
