Top critical review
Nice replacement option, but really short connections
Reviewed in the United States on September 30, 2019
I am going to give a bit of a neutral review here, as the option to use this model as a replacement did work well overall. On the other hand, the connections coming out of the ballast were extremely short. I had read this in previous reviews, but I didn't think it would be so much of a headache. I purchased two of these to replace a couple of "Universal 446-I-STF" model ballasts that went bad and are listed as compatible replacements. It is my feeling that if you are going to use this as a replacement for a 40" T12 bulb fixture, then you may want to source ballasts with longer leads. These made it extremely difficult to connect directly to two endpoints (the blue and red), while having enough room to remain in the center of the fixture and meet the yellow leads as well as the hot and ground. As a plug & play for my application, this did not work without reworking some of the existing wirings (and removing various covers) to extend to the new ballast and a couple more twist cap fasteners. It was, in short, a pain in the rear that took a couple more hours than expected. The construction looks fine, they are solid, and have decent weight. The lights come on in a flash (no pun intended) and everything is working fantastic. The wiring or lack thereof just annoyed the heck out of me. Be warned that when we say short, they are short.
