What is HDPE pipe. I googled it and all I could find was a black pipe that I think is what we call poly pipe, which makes me think that is what the "P" in HDPE stands for.
So am I correct and if so where do I find clear stuff. Would love some pics.

High Density PolyEthylene. Any colour you like, try a plastics supplier?:)Quote:

They had several sizes of rigid, clear tube. As I said, the size tube I bought was a perfect fit for that LED strip with the rigid backing still attached.
There may be some LED strips available that already have some sort of covering. I just wanted to be able to set it up just the way I wanted. In a lot of applications, there would be no need at all for the tube. In my case I wanted it to be pretty rugged. In a caravan, you could just slip the circuit board with the LEDs out, screw the mounting strip in place and then slip the circuit board back in.
I was thinking for cleaning. I want to put under cupboard above sink which is beside the stove. I am sure it will get cooking grime and would be hard to clean. In a tube it would be easy.Quote:

That is a good point about the cleaning.
I chose the strip I did instead of the one bee utey linked to because I thought 72 LEDs in 500mm suited me better than 60 LEDs in 1 metre. I also thought the acrylic tube might be clearer than whatever plastic was used in that flexible one. I didn't want the light diminished by translucent rather than transparent plastic. I also wanted to be able to set it up so that it didn't have cables permanently attached. I had the idea that they might be vulnerable as the light would be handled a lot, so I wanted a socket fitted to plug into. That wouldn't be a problem in a caravan
There seem to be a lot of LED light strips about now. Maybe with a bit of searching, you could find something that would be better in the caravan. I'm still convinced that my choice is the best one for my camper, but it might not b exactly what you need.
These photos might help. They are, in order:
1 The whole 500mm strip.
2 The neat end (apart from the glue that I forgot to clean off). You might get an idea of the clarity of the acrylic tube from this shot.
3 The less neat end because I forgot the length of the strip when I bought the tube.
4 Comparison with a 240 volt globe which I expect is 60 or 75 watts. The car interior light is on but doesn't register. The illuminated roof above the LEDs is probably between 1.8 and 2 metres above the LEDs. I know the shot is dark. That is what happens when the camera can see the light source. It is the difference between the light cast by the 240 volt globe and the LEDs that is important.
5 Another comparison. Notice the LEDs cast a shadow on the wall that is already lit by the 240 volt globe even though the LEDs are about the same distance from the wall as the overhead 240 volt globe.
The LEDs are pretty bright.
Thanks for the pics. I am now enlightened:Rolling:
Seriously though, I appreciate the input. Although these LED's are fairly cheap I would like to get it right first time. I want to get the brightest strips possible.
