High-Quality Flexible LED Sheets with Clever Heat Management

These LED sheets are exceptionally well made, with thoughtful installation instructions and a flexible design that can be cut in multiple ways. The copper electrical layer also acts as a heatsink, effectively managing heat. Color rendering looks beautiful even though the CRI is not specified. Placed under a thick granite countertop, the light diffuses evenly with no hotspots. They are very bright on direct 24V power and can be used with a dimmer. A power supply is not included, which is reasonable since requirements vary by application. Not inexpensive, but a top-quality option.

  • + well-thought-out installation instructions
  • + flexible and can be cut in many ways
  • + copper layer doubles as effective heatsink
  • + beautiful color rendering
