HDHalo Technology. These HD LED semi-flex strips have been designed from the ground-up to be absolutely the brightest most reliable strips physically possible. Each strip is populated with a large number of high-density (HD) LEDs which are then coated by a diffusing gel resulting in a perfectly uniform light when turned on. When off the diffusing gel hides the chips resulting in a clean OEM appearance.Sizing:All sizes are listed by total length in millimeters. Strips can be shortened by up to 20% but no less! Width is 8mm and total height is 4.5mm.Mounting: The strips must be custom-mounted in position using adhesive or beading wire using the integrated mounting tabs. If you wish mounting tabs may be removed with a pair of clippers or basic sanding. The strips can be modified if needed to fit certain applications. Up to 20% of the strip can be removed using side-cutting snips and still remain fully functional. Click here to learn more:
