Lots of discussion around angle, light, cable connector, studio lighting, sensor, maximum light level, and perceivable luminosity are described inside this product manual. This product manual contains discussion about analog input, light sensor, product manual, precision, human perceivable luminosity, input, and position.
In this product manual you can read explanation such as connector, cable, level, manual, product, precision light sensor, and luminosity. The following are excerpted from the product manual:
The human eye is less sensitive to changes in light intensity than the 1127, but is able to see a wider range. The Human eye range is from 50 µlux (starlight) to 100 klx (extremely bright sunny day). The 1127, on the other hand, is able to measure from 1 lux (Moonlight) to 1000 lux (TV studio lighting) The 1127 is able to detect higher frequency fluctuations in light levels than the human eye. If you notice noise on the signal that you cannot perceive yourself, it is probably due to incandescent light flicker, or other varying light sources. The 1127 is Non-Ratiometric which means that you cannot rely on the sensor saturating at 1000 SensorValue.
Furthermore, the product manual presents discussion things like cable connectors, right angle, manufacturer part, light level, analog, and input sensitivity.
