User questions & answers

Question:	Who manufactures the meter
Answer:	The name listed on the case, and the meter itself, is "Dr. Meter", and it is titled as "Dr. Meter Digital Illluminanc...B, O-200,000 Lux Luxmeter" model LX1330B. It shows a URL of "http.//www.drmeter.com". It was mfg. in China, but a USA contact is "Dr. Meter, 30075 Ahern Ave., Union City, Cal., 94587, w/ a phone number of #510-477-0249, & Fax as #510-477-0749.
Question:	Can this measure LED grow light
Answer:	Tl;dr is at the bottom because I have a lot of details. It can, but it is not recommended. Lux meters like this are designed to measure the intensity of visible light, which generally assumes you are measuring white light perceived by humans. What matters for plants (so what matters for your grow light) is Photosynthetic Active Radiation, PAR. PAR is a measurement of how many light particles, or photons, pass by a given point. This means that PAR will also get smaller the further you move from the light because it has dispersed more. Because PAR is much more difficult to measure than ambient light, it is much more expensive, generally in the $300-500 range. I would recommend either checking if your grow light has documentation on it's output in PAR, or contacting the manufacturer to ask. If they do not have this information, then follow their guidelines on how far to place the light relative to your plants. Tl;dr: Lux is not a good measurement for LED grow lights. See if you can find information about the light's output measured in PAR. Source: I designed an LED Grow Light and had to do all this research to figure out what to measure for it.
Question:	Yes this a goodlight meter for photographers
Answer:	I would not use it for photography. There are many better meters to use for that purpose. This meter is made for measuring foot candles and such and is useful for comparative light levels. Gossen or other photo meters would do better and be directly viewable with the scales on such a meter.
Question:	I want to measure light pollution from out door lighting. Need accuracy below 1 lux eg (0.1 to 1 lux
Answer:	From the instruction manual:Light-measuring levels ranging from 0.1 lux to 200,000 lux with auto zeroing and corrected for luminous efficiency function (manually calculated for non-standard light sources).Accuracy is described as: +- 3%+10dgt with a repeatability within 2%.ChuckJ

Flash Duration Measurements

Understanding flash duration is the first step in freezing fast-moving subjects. Since all cameras are limited to relatively low sync speeds, stopping motion in a single image is often achieved by leveraging short flash durations with the camera’s max sync speed. A long-held secret of some of the world’s most talented photographers, the key to freezing action consistently is found in being able to measure flash duration. Photographers are now able to do this easily for the first time, demystifying one of photography’s most challenging techniques.

Increased Light Sensitivity

Increased ISO capabilities in today’s cameras have created a need for light meters to increase their ability to measure light in the dimmest of settings. With an additional 3-stops of light sensitivity for incident light, 2-stops of light sensitivity for reflected light (spot), and an ability to capture a reading down to 0.1 lx of Illuminance, accurately metering scenes lit by candlelight or getting the right measurement for long-exposure night photography is now a possibility.

HSS Flash Measurements

The L-858D-U is the first meter of its kind that can measure the stroboscopic pulses fired from strobes when they are used for Hi-Speed Sync. Finally, photographers now have an accurate way of measuring their lights when they want to overpower the sun or achieve a very shallow depth of field through using HSS.

Flash Analyzing Function

The L-858D is especially useful for on-location shooting to lighten shadows or reduce background detail. That's because it measures ambient and flash simultaneously and automatically indicates the percentage of flash in the total exposure. You can easily adjust the ambient flash mix by turning the Jog Wheel. The digital display indicates the camera settings and an analog display shows the relationship between ambient and flash and the total exposure.

• Measures luminosity from 0 to 200,000 Lux and ambient temperature
• High accuracy of ±3% rdg ± 8 dgts (10,000 Lux)
• 4 digital color LCD screen, MIN/Max readings, data hold, auto power off, and low battery indication
• Handheld design, lightweight and compact, easy to transport
• Wide range of application, use lux light meter for set design, factory, office or home use

Answer:	It should, I believe that’s called lock rotor amps and I’ve measured it with other and apmprobes.
Question:	Does the sensor head rotate 180 degrees
Answer:	No, it is not.
Question:	Does this read iso or shutter speed for photography
Answer:	The meter has a hold function and inherently measures the max value but I'm not sure that it retains it for recal.

Extech Basic Accuracy 40-40,000 FC LED Light Meter.

• Measures LED and Standard lighting
• For White and Color LEDs
• Lux or Foot Candle units

User questions & answers

Question:	Does this item come with calibration certificate
Answer:	Nope. Lux and footcandles. Good basic unit but remember you get what you pay for.
Question:	Can you give me a calibration certificate with this unit
Answer:	Yes but the color temperature of the source may effect the sensation of “brightness”. The higher the color temperature, the sensation of brightness increases. We have “caveman eyes”: sunlight (6500k) “feels” bright....fire (2000k) “feels” dim. Look up anything published by Dr Sam Berman.
Question:	What is the lowest fc reading this unit will take? Will it measure as low as 0.02 fc
Answer:	It has been very good. We have used them for a while now.
Question:	Currently using a "Testo 540 " Light meter. Doesn't seem to get full fc when reading LED. Will this meter give a better fc for LED light
Answer:	You will need to purchase the cable that has the data send button on the cable. The on/off button does not send the data.
