Sunco 50 Pack T8 LED Bulbs 4 Foot, Tube Light Bulbs Ballast Bypass, 48 Inch Fluorescent Replacement, 2200 LM, 18W, 5000K Daylight, Single Ended Power, Type B, Frosted Lens UL

Ordered a 50-bulb pack of 4' T8 LED bulbs from SUNCO. Order was received quickly. Bulbs were VERY well-packed, undamaged. Have installed about twenty bulbs so far, all worked perfectly and very brightly. Removing the ballasts and rewiring the fixture for direct contact to the bulbs was a very simple job, reusing the wire in the fixtures. The fixtures were originally a mix of T8 and T12 bulbs and old magnetic ballasts and newer electronic ballasts, and the T8 LED bulbs fit and operated perfectly in all after the minor rewiring task. The LED bulbs are instant on, even in very cold temperatures in an unheated shop building, and give full brightness even at the low temperatures. The SUNCO LED bulbs were an economically priced, high-quality solution to replacing and upgrading the old fluorescent fixtures in my shop building.

Excellent product. We were replacing fluorescent tubes and found these Type B LEDs at a great price and very reliable. They are well packed and provide excellent illumination.

Great product and easy to install love the better lighting in my shop

i purchased these in April 2025 in advance of a scheduled warehouse maintenance day since this requires a mobile platform to install and movement of production work areas. Installed them today and installed 60 of the 100 units purchased. We stopped because six failed within the first 60 minutes of operation. We stopped pulling out our fully functional flourescent that have been in place for 12 years and decided to find a more reliable lamp. The ends of the failed units are HOT, white plastic turning brown due to heat before the lamp changed from normal illumination to a flicker. Lamps say UL on them but it seems to be a risk to run them. For the 90% (so far) that are running, the lamps ends are cool as you would expect.

So far so good, just installed all 50 and all were bright nice less. Here's to hoping they last a good time. Great for the price

Exactly as described. All bulbs worked.

I am so happy with these bulbs which I used in the garage. It is like daylight in there. Keep in mind with these particular bulbs you need to remove the ballast and rewire. I wanted to do that to increase reliability and also reduce power usage. They are so bright and clean looking.

These work perfect. Exact size and easy to follow directions for ballast removal.
