Is My Light Meter Reading in mLux or Lux?

Click For Summary
SUMMARY

The discussion centers on the interpretation of light meter readings, specifically whether a setting of 2000 indicates readings in mLux or Lux. Participants conclude that if the light meter is set to 2000 and the reading is 1253, it translates to 1.253 Lux, assuming the unit is indeed Lux. The conversation emphasizes the necessity of knowing the specific make and model of the light meter to provide accurate guidance. Without this information, the interpretation of the readings remains ambiguous.

PREREQUISITES
  • Understanding of light measurement units (Lux and mLux)
  • Familiarity with light meter operation and settings
  • Basic knowledge of light intensity standards in various environments
  • Ability to locate and interpret user manuals for electronic devices
NEXT STEPS
  • Research the specifications and user manuals for various light meter models
  • Learn about the differences between Lux and mLux in practical applications
  • Investigate standard light intensity levels for different settings, such as classrooms and auditoriums
  • Explore calibration techniques for light meters to ensure accurate readings
USEFUL FOR

Physics students, lighting technicians, and anyone involved in measuring light intensity for various applications will benefit from this discussion.

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
