Lab photo cells, Nairobi Industrial Area

Lab photo cells, also known as photodetectors or light sensors, are devices used in laboratories to measure light intensity or detect light in various scientific experiments. They typically convert light energy into an electrical signal, which can then be analyzed. These cells are crucial in experiments involving light absorption, emission, or reflection, often used in photometry, spectroscopy, and other optical measurements.

A good description would be:

"Lab photo cells are sensitive light detectors that convert incoming light into electrical signals, providing precise measurements of light intensity. They are commonly used in scientific research for applications such as spectrophotometry, optical sensing, and light detection in various laboratory experiments."
