Answer This Question

A:  Hi RonP - this LED tube is an InstantFit or "Type A" / Plug and Play bulb so it does require operation with a working, compatible ballast. This will not work in a ballast bypass/direct wire operation.

    One out of 8 tubes smoked on me.
    Back on 3/6/2023 I purchased a 10 pack of the 5000k tubes. The 8 tubes in use worked great out of the box until last month 1 tube started sizzling and spewing out smoke when I turned on the light. I immediately turned off the light and removed the bad tube. I put one of my spare two tubes in its place and all was great. The part that I will say to watch out for is trying to do a warranty claim is VERY difficult. I am 4 weeks into trying to get a claim and they are being difficult.

      Super Bright and Easy Install!
      These are a great substitute if you are looking to change out your old fluorescent lights for LED lights. They are a little more expensive than fluorescent bulbs but they have lower energy costs and will last a lot longer. At 6500K, these are the brightest lights that I could find for my garage and storage area. The light is VERY white and bright, which is what I was looking for. If you don't want to remove the existing ballast, these are the lights to purchase. Look for the UNIVERSAL label. Basically, they are "plug and play." Take out your old fluorescent bulb and simply put this one in. (There are other options available from Philips if you want to remove the ballast and perform a direct wire connection.) So far, I'm really happy with the performance of these lights. Philips offers a good product at a competitive price so I think you will be pleased. Please remember to recycle your old fluorescent bulbs.

      These lamps fit just like the fluorescent ones they replaced. I bought the equivalent color temp and there is almost no difference side by side. Very happy about that.

      These are a great replacement for the old fluorescent bulbs in my kitchen. While some people don't like operating room brightness, sometimes you need the daylight brightness that these give off when you are preparing a meal or cleaning. These are 6500K which gives off a white daylight as compared to the 3000K fluorescent bulbs that give off a yellowish cast. These are a great improvement in the laundry where there can never be enough light
