No worries. I should have been a little more thorough in my explaination. Apologies. Yes, you can use it to make fluorescent lights - which is what I did quickly in the image above so it's probably not the best representation. Other usages would be to put a single tube light in an enclosed long hallway. That way, with a single bulb, you could have a consistent effect down the length of the hall (fall off, shadows, etc). If you had a light saber from Star wars sitting on a table and retracted the blade in an animation, you could animate the size of the tube light as the blade retracts. There really are tons of uses but you need to make up most of the uses yourself! Does that help? Mark
