KastLite T8 Fluorescent Light Tube Guard with End Caps, 46-3/8" Fluorescent Light Diffuser Covers/Safety Sleeves, 4th of July Red/Blue Protective Plastic Covering/Lighting Accessory, Pack of 6

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.

These tubes are great! The colors look great and the plastic doesn't feel too cheap. The lighter colors could be a bit darker but that's just my preference. The delivery was way faster than expected. I will purchase these again if I have to.

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.

Arrived on time, as advertised.

They're awesome!

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

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.
