Did not mark any of the above, cuz not sure of quality/value so I won't be able to recommend this product. Replaced the first ballast in October of 2006, and replaced it again this year in February. So it has been about 11 years. Now, whether this is the norm, I don't know! All I can say is that 11 years of use is sufficient for me, and I am very satisfied with the product.

Sumpark ballast makes fixture work like new. Much cheaper than similar ballast offered in stores.

Great $ for a solid replacement ballast. Looks like a newer version I replaced. Been about a month still going strong as a kitchen light

It brought my light fixture back to life.

The ballast itself worked fine, but the leads to the lamps are extremelly short. This made mounting and hooking up the ballast difficuly. Another 3 inches on each lead would make it a real winner.
