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

User questions & answers

Question:	Can you measure how bright a light source (such as an led light) with this while other lights are on by turning on and off the source? thanks
Answer:	Hi , the audio capture will work as there 4 audio imputs to the back of the DVR. i bought one to test for just about $25. 00 . its been working good so far. my last system didnt have that option but this was a plus . if i can locate the link for the audio cables i will send on this platform . hope this helps
Question:	can this meter measure outdoors areas where there is very low light from nearby street lights
Answer:	Hello, Thank you for reaching out to us with your question. We do not have any compatible cameras to this system with audio features. We would recommend you look into any of our Swann NVR kits. These will have 1-way or 2-way audio. Please let us know how we may further assist you, Thank you. JV Swann Customer Support
Question:	What is the spectral sensitivity of this sensor? It is integrating wavelengths, what is the bandwidth of frequencies it covers? thanks
Answer:	It can be used for 2-3 hours with electricity, but if you need to use it continuously, just plug it in.
Question:	What is the difference between this and the 881e aside from lux range
Answer:	you can follow someone across the yard with the controls, but it is not automated that way. It Will automatically turn on when somebody walks in front of it. But everything else is manual.
