In addition, LED panel lights are available in a range of color temperatures, from warm white to cool white, and can be dimmed to adjust the level of brightness as needed. This makes them a versatile lighting option that can be used in a variety of different settings

One of the main advantages of LED panel lights is their energy efficiency. They use significantly less electricity than traditional fluorescent lights, while still providing the same or even better levels of brightness. They also have a longer lifespan and require less maintenance, making them a more cost-effective choice in the long run.

LED panel lights consist of a flat panel that is typically square or rectangular in shape and contains multiple LED chips. These chips are arranged in a grid pattern and covered by a diffuser material, which helps to distribute the light evenly and reduce glare.

Vertically scanning white light interferometry is a non-contact optical method for 3D-profiles of rough and smooth surfaces (Dresel and Häusler 1992; Windecker and Haible 1995). Instead of coherent light as it is used in classical interferometers, a polychromatic broadband, incoherent light-source like an LED or a halogen lamp is used. So it is possible to measure the topography not only of smooth but also of rough surfaces without disturbing speckles and, in case of steps, the order of the interference fringes is not lost. The z-resolution can be in the picometer range, independent from the field of view. Changing optics like objectives in a microscope-interferometer does not influence the z-resolution. The field of view depends on the optical setup of the instrument: For telecentric systems, e.g., it can be as large as 50 × 50 mm2, for typical microscope-systems its higher...

LED panel lights are a type of lighting fixture that uses light-emitting diodes (LEDs) to produce bright and even illumination. They are typically used as a replacement for traditional fluorescent ceiling lights in commercial, industrial, and residential settings.
