highly recommended

Decent light meter for the price.

For the price, this meter is decent and fairly accurate. It doesn't have all the features of a higher end light meter, but does measure in both Lux and FC. I use it on stage to make sure the lighting is fairly even.

Good for general purpose, but not for science.

This is a fine light meter for general all around use, but it's sensitivity graph shows it to be highly non-linear over the spectrum. Basically it measures light that humans are most sensitive to. For that it's great. But if you are trying to measure light at different wavelengths, like for example grow lights, aquarium/reef lighting or any other specialized lighting this meter is not going to do the job unless you know the wavelength you are measuring and feel you can trust the little graph (1" square) in the "manual" to make corrections to the results. I'm not knocking the product, it's just not useful for anything other then general purposes.

Needs measurement in solar rads

Unit is practical and has good range. For my use it would be nice to have some way to measure in solar rads but a conversion can be made.

a worthy meter

I recently received the Mastech meter to monitor the lighting in my nursery. I found it easy to use although the directions might be a bit improved. For instance, putting in the supplied battery it's necessary to remove the rubber casing. The instructions said to slide off the battery cover in the direction of the arrow but there was no arrow and the cover wouldn't securely fit unless the rubber case was on. It took a little practice to figure out the scales since pushing the range button wasn't simply reflected on the LCD, especially on the lower ranges (afterwords it would show 10x,100x, etc.)It would have been nicer had it shown the actual amount on the readout within a particular range rather than having to multiply it by one of the factors. I should emphasize that the above quibbles are very minor and that the meter performs it's functions very well. The meter is well built and the rubber casing and sensor cover afford it excellent protection. Both the sensor and main unit are light weight and easy to grip. The readings I got were consistent time after time.I think that for the money it's an excellent buy and superior to most others on the market in its price range or even some higher priced ones. I would recommend this meter for anyone who wants a reliable meter that covers a great range and is very affordable.

great

Works great. If you're an electrician or in the lighting business, this is a must have as the electrical code mandates how much illumination certain areas of a building must have.

If you're a photographer, this is NOT what you're looking for. This light meter gives you the amount of light in LUX and candle powers...no information at all about the f/stop or ISO or anything like that ;)

The newly released Sinometer Luxmeter LX1330B is a lux meter with wide measuring range and lots of nice features. A luxmeter is used for checking the level of illuminance, the light falling on a surface, It is defined as: 'the density of the luminous flux incident on a surface'. It is the quotient of the luminous flux by the area of the surface when the latter is uniformly illuminated. - (E = df / dA). This convenient gadget is widely used in many areas such as construction, inspection, photography, greenhouse gardening and etc. The LX1330B can measure from 0 up to 200,000 lux, you can switch the units between lux and footcandle by simply pressing a button. It's powered by a 9V battery, which last for 200 hours or even longer. Other nice features include data hold, auto zero and more. Specifications: Power: 9V x 1, Ranges: 0-200/2,000/20,000/200,000 Lux , Accuracy: ±3% ±10 digits (±5% ±10 digits as over 20,000Lux), Repeatability: ±2%, Temperature Characteristic: ±0.1%C , Photo detector type: Silicon Photo Diode with Filter , Operating temperature: 32-104 degrees F (0-40 degrees C), Sampling rate: 2-3 times per second, Battery life: 200 hours (estimate), What's in the box: Mastech Luxmeter LX1330B, Carrying case, 9V battery, User manual.
