Ooh, this is a great solution. We had to get new shelving and went with wire surfaces instead of wood, which meant we had nowhere to mount LED's above the tanks. This would be super easy to suspend from wire racks!

those LED rope lights
There is a wide range of LED tape available, some of which would be suitable (SD panels use LED tape, and are very good lights). Unfortunately, most of the offerings commonly available (on Amazon, etc.) don't list watts, lumens, color temp, or really any useful information other than price and how cool your backyard barbeque will look when you have these flashing different colors.

Here's some -- apparently -- good strips.

There would be a lot of research necessary in order to build something that's actually functional, and it isn't clear that there would be any savings vs buying something of a proven design.

I hate to be a Debbie downer but this is not a good idea for vivariums and its hard for me to see a scenario where it is, that would not have a better solution.

What makes LEDs better than other lights is the fact that they are directional. Wrapping them around a tube literally takes the biggest advantage that LEDs have and reverses it to make them have the disadvantages of fluorescent lights.

Remember the days of fluorescent lights? People spent a great deal of effort and money to try to get the best reflectors to reflect more of the light down and waste less of it. But no matter what they bought or how much they spent light was still wasted.

LEDs are efficient and just so happen to direct all the light into the vivarium and that makes them even more efficient in certain scenarios, IE vivariums, street lights or ceiling lights where you have no interest in shining the light in more than one direction.

I agree with all that.

I remember the heyday of T5HO in reefing when we all spent more on top-of-the-line spectral aluminum reflectors than we did on the lamps themselves, trying to minimize restrike. Even that was less than ideal; foil tape isn't much of a reflector at all.
