Originally from ticket #12212.
I have had an Outer Orbit HQI/T5 model number 1070-1074 Lighting system since 2007. I have changed my bulbs every 6 months (last time was Oct 10, 2011) Today my left bulb blinked and went out. I switched bulbs and the new one wouldn't fire up. Possibly a balast problem. From your web site I found a 120-HMI150 balast. Would this be the correct part to replace the balast in my system?
Thank you for contacting Current-USA.
Yes, this would be the correct ballast for the system you have and should solve the issue.
