LED strips are designed to be very flexible. Their PCBs (printed circuit boards) are so robust that many LED tape products can be bent up to 90 degrees with no difficulty.
But be aware that higher-power LED strips are less flexible than lower-power ones. This is because the LED modules are placed closer together on high-power strips, and require wider PCBs (for more heat dispersal).
The 5-watt white LED tape shown here has 60 LEDs per metre, mounted on an 8-millimetre-wide PCB.
For comparison, we’ve got pictures illustrating the flexibility of some more LED tapes below…
