Great product and easy to use!

Cumple lo indicado en la descripción buena relacion precio calidad

Very nice and seems accurate. I accidentally left a negative review due to confusing this with different product. I can’t find that review to edit it

I have been seeing many people claiming this meter and Lux meters in general are not accurate.I tested outside on a sunny day and got about 100,000 Lux, this is normal for the sun at the time of day I took it.I tested again on SpiderFarmer LED grow lights on seedling stage against my PAR meter. I used several different equations until I was able to find a website via googling that allowed you to convert the LUX from various models of grow lights to PAR. I tested on various models until I found the model with the closest PAR to what my PAR meter was showing.Unfortunately, this means without a PAR meter, this won't be very useful. But this is not the fault of the device. Lux is a much simpler "dumber" tool that does not account for wavelength or color temperature of the lighting like a PAR meter does. For the limitations of a Luxmeter, this unit is not bad.I do have 2 complaints where I think the manufacturers could have done better.1. 9v battery. Why are we still using these? Other Luxmeters use 3x AA batteries which are much easier to get in rechargeable. 9v rechargeables are often unreliable and break, or devices will not accept them. Thankfully, this unit accepted my Tenergy NIMH 9v battery without issue.2. Must set range on the device. I originally couldn't get the device to work, then I figured out like a digital multimeter, you must set the range on the device and add the zeros at the end. An auto range feature would have made the unit easier to use and read.Lastly, not a complaint, but I appreciate the sensor protector included on the device. My PAR meter doesn't have one so I have to be extra careful with it.Overall I like the device. But if you are using it for indoor LED lighting for plants. You will still need a PAR meter.

I find this inexpensive meter extremely useful for assessing lighting conditions at venues where I am taking photographs and videos. That said this is not a photographic exposure or flash meter and unfortunately if you are purchasing it as an inexpensive substitute to use for that purpose you will be disappointed.This meter gives you a simple to understand Lux reading corresponding to the brightness in the room. Our eyes are amazing self adjusting optical miracles... they compensate for conditions so much that we often have a difficult time judging just how light or dark conditions really are.Modern cameras and video cameras have sophisticated reflective light meters built into them and if used in an auto or semi-auto mode they will adjust the images we take for overall brightness. They will also predict whether the exposure will be under or over-exposed in manual as compared to a photo that is an even 18% gray. Very few people use traditional exposure meters these days. The problem for most is that if they try to take pictures or video in dimly lit areas without a flash or other external light source the camera (or you) can try to compensate with very slow shudder speeds, very high iso settings, along with the widest aperture your lens has available. It is decision making time as to how you are going to get your best results. Because of improved camera sensor technology this is less important these days than it once was, but this is still a recipe for pictures and videos that have poor image quality.I use the readings that I get from this light meter to help decide how to set up my equipment and/or adjust the lighting for the most satisfactory video of photo taking environment. One could accomplish the same thing by taking sample pictures and videos (which you most the time one has to do also), but I find the meter to be a time saver for initial decision making. I have a much more sophisticated and much more expensive photographic exposure meter. It is more complicated to set up and is overkill for this purpose most of the time, but this is the type of light meter that most photographers are looking for.This meter does only one thing... it measures the brightness of visible light and gives back a number representing either lux or foot candles. There are free android calculators and also charts that one can quickly convert these numbers into exposure settings, but this is not what this meter was designed to do. For novelty I have checked whether the readings are useful for this purpose and have had mixed results as compared to our actual photographic exposure meter. Since this is not what the meter was designed for you have to make adjustments to the results you get and the reflective meter built into the camera is more accurate. A modern photographic exposure meter has many more options in the way that light can be measured and gives it much more flexibility. The one I have has inputs and attachments for spot metering and flash metering. Of course it also automatically calculates recommended exposure settings.In my opinion this is a great meter and for me it has been a big time saver for assessing and adjusting the lighting conditions at an event where one I have set up video or photographic equipment. But... this is NOT a photographic exposure meter. While both are built up from similar sensors they are not the same tool. This cannot accomplish many of the tasks one purchases an exposure meter for such as setting up flash equipment. If you are trying to fine tune the results you get from your camera this is not going to help much if at all. I hope that is a helpful explanation and also explains why people have felt misled and others have said it is not suitable for photography.

Works great, like how intuitive it is to use and fast results.
