    Light Meter Reading
Click For Summary

Discussion Overview

The discussion revolves around the interpretation of light meter readings, specifically whether the values obtained are in milliLux (mLux) or Lux. Participants explore the implications of the meter's settings and the need for additional information to clarify the readings.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether the light meter readings are in mLux or Lux based on the setting of 2000.
  • Another participant suggests that if the reading is 1253 with a setting of 2000, it could indicate 1.253 Lux.
  • A third participant emphasizes the need for more information about the light meter, such as its make and model, to determine the units accurately.
  • One participant states that the meter is measured in Lux and mentions a knob that adjusts settings to 2, 20, 2000, and 20000.
  • Another participant notes that without the manual, it is difficult to provide assistance and mentions typical Lux values for various light sources.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the units of measurement for the light meter readings, and multiple viewpoints regarding the interpretation of the readings remain. The discussion is unresolved due to the lack of specific information about the light meter.

Contextual Notes

Participants highlight the importance of knowing the make and model of the light meter and the absence of the manual as limitations in determining the correct interpretation of the readings.

Hi, I'm studying physics and was wondering about the light meter I used. It was set to 2000 so I could get readings, instead of 2 because the readings wouldn't show. Does this mean my values I get from the light meter is in mLux (milli) or just Lux?

I am just guessing here because I don't have the manual that came with your meter. If your setting is 2000 and the reading is 1253, then it means 1.253 Lux.

or 1253 Lux ... depends on what the units of the 2000 is

mate, you really need to tell us lots more info
Make, Model even a sharp and clear photo of the front of the unit would be extremely helpful

2000 means nothing to us if you don't tell us the unitsDave

I don't have it with me. It's measured in lux. there's a knob that turns to 2, 20, 2000, 20000

do you have a manual for it ?

if not, there's probably one online

it would seem that it measured 1253 lux, which is a pretty bright light source.

Just an aside for light sources, the avg data projector for a home or board room is from 1500 - 3000 lux

a good number are much higher 5k to 8k lux for larger auditoriums

so, till you provide more info, no one can help youDave
