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

The Sekonic L-308X-U Flashmate

A pocket-sized and exceptionally accurate light meter that holds a legacy of accuracy. The Flashmate L-308X-U light meter from Sekonic is a compact tool for metering both ambient and flash lighting as well as working in video with dedicated Cine and HD Cine modes.

Pocketsized and Powerful

The L-308X-U is able to measure ambient light as well as reflected light via a lens with a 40° reception angle. This meter also has a wide metering range; from 0 to 19.9 EV at ISO 100, and can work with flash within a range of f/1.0 to f/90.9 at ISO 100. Repeat accuracy is also important when metering, which the L-308X-U delivers with a rating of <0.1 EV on repeat exposures.

Photo Mode

The L-308X-U offers full exposure control for photographers on-location or in the studio. Measurement data for flash and ambient light readings are clearly displayed on screen, as well as ambient EV measurement. In addition to Shutter Priority Mode, the new Aperture Priority Mode offers photographers care free measurements where depth-of-field is critical.

HD Cine Mode

Gives cinematographers a compact solution for scouting locations or as a quick go-to solution while they are on set. The 308X-U lets users select from a range of frame rates and shutter angles, while measuring accurately, to within one-tenth of a stop. Also, the addition of ISO 850 greatly assists cinematographers by giving them the option of taking measurements in the native ISOs of many of today's professional cinema cameras.

Product description

The flux of light received in a unit area of a certain side being shown is popularly known as illumination. The measuring unit in both United Kingdom and America is known as footcandles light,

but in Europe it is also known as meter candlelight. One foot-candles light is the illumination of light that falls on one side which is one foot away from a one foot-candlelight and exactly

intersecting with the light. Its abbreviated form is written as 1 Fc=1 Lm/ft, similarly, one-meter candlelight is the illumination of light that falls on a side which is one meter away from a

one meter candlelight and exactly intersecting the light. It is also called Lux i,e. the flux of light being received in each square meter is called the illumination of one Lumen.

• Measuring lights source: LED white light and all visible light.
• Measuring intensities of illumination in Lux or footcandles.
• Many applications include: Warehouses, factories, office buildings, restaurants, schools, library, hospitals, photographic, many video, parking garages, museums, art galleries, stadiums, building security.

User questions & answers

Question:	Does this product work well for measuring the intensity of a blue light 450nm led
Answer:	Found this meter USELESS for measuring the light output in my grow tent! It only measures LUX output, then you have to calculate a conversion. If you want one of these, will sell you one REALLY Cheap!
Question:	What should it read under a 450watt led viperspectre
Answer:	check viperspectra specifications, should list lumens/lux for a given distance & area with respect to +-4% error. Under test the 450w led should be the only light source. Lumens to lux conversion, mathematically, 1 lx = 1 lm/m2.
Question:	Can it measure the blue light emission by a display
Answer:	I don’t think it will.

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:	Thanks for the question. Yes, BT-881D can measure light intensity in Lux and Foot Candles. The meter is very sensitive, we'd suggest you turn off the other light source to measure the ONE you wanna test.
Question:	can this meter measure outdoors areas where there is very low light from nearby street lights
Answer:	Yes it can
Question:	What is the spectral sensitivity of this sensor? It is integrating wavelengths, what is the bandwidth of frequencies it covers? thanks
Answer:	Lux meter mostly cover green light. You need a par meter is f you want to measure outside of green wavelengths.
Question:	What is the difference between this and the 881e aside from lux range
Answer:	Hi, thanks for the great question. Only the lux range are different, the other functions and appearance are all the same.
