KastLite T8 LED/Fluorescent Light Tube Guard with End Caps - 46-3/8" Lamp Diffuser Covers & Safety Sleeves, Multi Colored Protective Plastic Bulb Covering & Overhead Lighting Accessory, Pack of 12

Arrived on time, as advertised.

They're awesome!

I read the reviews before purchasing these and I was really concerned that they weren't going to do what I was hoping them to do because there were so many reviews about mis-matched colors and reviews about them not changing the color of the bulbs very much, etc. But - I'm here to tell you that these things are awesome and you can order them with confidence. They completely change the color of the light and it's quite vivid and a significant color change. We also had no issues with any mismatched colors.

As other noted there is a lot of color variation. Most of the sleeves are amber however 4 sleeves are yellow, not even a slight difference in color but an easily noticeable difference. I guess I will need to order another pack of them and hope I get 4 amber colored sleeves. I can't return part of a package. On the positive side the amber is a nice amber color

I ordered these tube lights from KastLite for my classroom and they are wonderful! When students don't need as much light, these filter out the bright rays and leave a beautiful ambiance. Customer service was excellent. I highly recommend these.

We thought the price was ok and you ship fast. We were very happy when we received the item because we love the colors. We put the green one in the Juke Box and it really lights up the area it's in.

Could barely even see the color. Even after I sliced and slid 4 of them on each light still unsatisfactory

I ordered a set of six light blue tubes and really liked them after installed (middle light in the pic). I needed 12 for my project so I ordered another six light blue. When they arrived they were a much lighter shade than the original 6. I contacted the seller and they were very responsive and sent me another set of 6. This set was extremely dark blue (see the light on the left in the pic). I contacted the seller again, they were again very responsive and nice and sent me another set of tubes this fourth set did not match ANY of the previous three sets. I now have 24 tubes with no 12 matching. While I am sure the seller would remedy this somehow, I have spent way too much time on what should have been a few hour project and am giving up. I'm out my money as the return window has passed. The only reason there is two stars here is that the seller was so nice. If you want more than 6, order them all at the same time.
