## Description

4 Lamp Universal Voltage Instant Start Quicktronic Electronic Fluorescent Sylvania Ballast for 32 watt T8 Fluorescent Sylvania Light Bulbs

Review: Ballast is a great value and performs very well - Purchased 2 to replace aging Motorola ballasts that had over 10 years of 8 hours/day use. And these are a great value in just under half of what the home improvement stores sell them for and a third the cost at a lighting store. These went in very easily. The wires are attached to the ballast so I only needed to remove the wires from the bulb socket ends and plug these in. It is almost fool proof. Red wires on one end and yellow on the other end of the bulb. And the other set of bulbs get a blue wire and yellow on the other end. As long as red and blue are not on the same bulbs, its good to go, just follow the wiring schematic on the bulb. I since put in both ballasts and have purchased two more to keep as spares. I did have a bulb go bad on one of the new ballasts and it was very forgiving. Put a new bulb in and it was running again. The old ones seem to knocked out by bad bulbs. The Sylvania seem very robust. They work very well. In fact I have a spare fixture that I already have wired with a new ballast to make change out a snap. Its not really necessary, but having the spare fixture and getting the wires laid out ahead of time works for my shop. The only thing that would have been better...I should have gotten all 4 in the first place. But shipping was very reasonable. And I will order these again.
Review: Works well, easy to install and now really instant ON. - Bought several of these to upgrade my flourescent fixtures in our garage, laundry room and master closet. I originally tried the 48" LED bulbs in our closet and one garage fixture, and even though they were quite bright, two only lasted a few days and the cost is still astronomical. I have since re-wired the garage fixture using one of these back to flourescent and upgraded to T8 bulbs. Very bright and instant on, the old flourescents were much dimmer, whould take a lot of flickering to come on and always had magnetic waves in them. Rewiring takes a slight bit of McGiver knowledge as I re-used the tombstones that required a bit of re-engineering to get them to make solid contact with the wires. Wiring diagram is included and fairly simple. I replaced two ballasts per fixture with this one as I have 4 bulbs in each fixture. What a difference in the garage and laundry room. My wife almost needs sun glasses for our master closet. I did use 5000K bulbs rather than the warmer 2700K bulbs. But if you do as I did, get the bulbs locally, I ordered a large box from desertcart and several arrived broken. desertcart is known for their customer service, so I just contacted them and returned the entire box for a full refund. Thanks desertcart, that is why I am a loyal customer.

### ⭐⭐⭐⭐ Works great though slight pause on each startup
*by N***Y on September 15, 2013*

There's a slight pause from the moment I click the switch until the lights come on (half a second) which is different that original operation before this ballast was installed but it seems to do the job and was certainly a good price. Installed in a 4-bulb ceiling fixture, replacing two OEM ballasts that were failing after 7 years of use. The bulbs were a little dark in the middle when first started. After 15-30 minutes, all four new bulbs were brightly and uniformly lit. The power up brightly every time now, albeit after that brief delay mentioned.
