Yes Real UV light
To make me feel better that these lights were real I bought a UV test kit. I took a photo of the test strip and the lamp I bought from LSE. I was very happy these were UV-C!

Smaller than it says.
The bulb seems like it is good quality however the information says it is 34.5 inches long but it is really more like 32 inches. I think it will still work but this needs to be adjusted.

Make sure all breakable items are packaged and padded correctly .
Fortunately the the uv bulbs were intact because the the tubes that the bulbs were picked in weren't padded inside the outer box . The box itself was left propped up at the side of our wheelly bin for anyone to take. Apart from that the order was received a week earlier than scheduled ,thank you.
