'qt 3x32/120 is' = quicktronic, three bulbs @ 32 watts each, @ 120 volts ac, and instant start... hope this helps.. **Q: I have a 3 lamp qtp3x32t8/120 isn-sc ballast 120vt, will this work as a replacement?** A: I may be missing something in your question, but isn't that exactly what this item is? It seems to be exactly what you're looking for. **Q: We have to replace ballast e213164 ( js165a) t12 in our under counter flourcent light. unable to find. please help.** A: The original is a Sylvania ballast? I had this problem with an old ballast. The manufacturer had for some reason changed the model numbers for its ballasts! It was in fact available under another number. Call the manufacturer. I am lucky to have helpful electrical supply people around (that is, not big box stores). There are conversions between model numbers, but you have to know that. **Q: Is this high or low power?** A: High or Low Power? in what way do you mean? it's specs list it as being able to run on 120 - 277 vac; that's high voltage.. it is an instant start ballast so it uses higher voltage initially to start and then drops down during operation... as M Hopkins said, the ballast has to be matched to your application.. this particular ballast will run up to three 32 watt T8 bulbs... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product and great price, quick delivery *by D***R on November 21, 2022* Quick delivery, same as original makes it easier to install ### ⭐⭐⭐⭐⭐ Great Replacement Ballast *by C***6 on April 22, 2013* This Sylvania replacement ballast was easy to install, was a great direct replacement for the original failed ballast in my shop light. Unbelievably quick start up. Just plug the cord in and the shop light starts right now! The price could not be beaten and shipping was very fast. ### ⭐⭐⭐⭐ Round 2. LED application, light it up. Maybe it will, maybe it won't. *by A***H on December 14, 2019* Well, this is my second review for this product. My initial review is still attached below. That one was 5 out of 5.This one, I'm gonna give it a 4.Made the order to add a ballast that would run LED's. The unit came a bit scraped up, but the vendor stood up to make me happy with the purchase. An actual contact. A promise to make things right if I have any problems. That goes a long way for me.My review from the first time I ordered:.Purchased to convert a T8 2-bulb shop light to be able to use new LED bulbs.Shipping was fast, and the instructions on the unit were spot-on for wiring up.Wire the black wire to the hot side of your plug (the narrow blade), and the white wire to the neutral side (wide blade). Then just use wire nuts to connect the remaining wires as explained on the picture.Pretty darn easy.Light works perfectly now. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/11819418-sylvania-ballast-quicktronic-49945-120-227v-qtp-3x32t8-unv-isn](https://www.desertcart.vn/products/11819418-sylvania-ballast-quicktronic-49945-120-227v-qtp-3x32t8-unv-isn) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
