Rated 3 out of 5 by Great Ballast This is a good product, from sylvania. April 11, 2014
Rated 5 out of 5 by Very good value My company recently changed vendors from Slyvania to GE. Our GE vendor doesn't carry this particular ballast which I have over 400 fixtures that uses this type. I was looking all over the internet when iI came acrooss I contacted the sale rep and got a great price which was over $7.00 less than I paid from my old Sylvania dealer. I also contact for all the blubs my current vendor doesn't carry. You guys are fair priced and ship your product on time. I will continue to use for all my hard to fine lighting. Great company I give you 5 STARS!!! April 5, 2014
Rated 5 out of 5 by Glad I found this site, 1000 First I got the product (ballast) in record time, about 3 days. Wow. but, when I opened the package I saw wires all over the place, oh my God, what am I doing? This new one had 8 wires coming out of it and the one I was replacing it with had only 4, oh boy! So, well, let me look at the directions, like any man, something I hate to do. Swallowed my pride looked at the directions, (which were excellent) I had it all hooked up, RIGHT, the first try, and it worked, of course. Wow. Thanks everyone. March 27, 2014
Rated 5 out of 5 by common product, but easily available thru 1000 Bulbs The price is cheaper than national retailers and we use them very often in the older T12 fixtures. July 29, 2013
Rated 5 out of 5 by Best price, excellent product! 1000bulbs had the lowest price on the Sylvania T8 lamp ballasts used in my orchid growing laboratory. These Sylvania ballasts keep getting smaller, more efficient, yet maintain the high performance and direct replacement foot print I require for my operation. July 18, 2013
Rated 3 out of 5 by Great if you don't have a lot to replace This ballast is priced really good. The main rub I have with this product is that the wire insulation is very cheap and of poor quality, This makes it a pain to strip. When your 40 feet in the air and have to tug and strain just to strip wire its not fun. So if you just have the occasional ballast to replace here and there these are great, but if your doing a lot in say a warehouse I would get something of higher quality. June 26, 2013
Rated 4 out of 5 by good price on a quality product These ballasts are perfect replacements for the original equipment that comes with many commercial fixtures. ships promptly and has competitive prices. I'm completely satisfied. May 13, 2013
