Amprobe LM-120 Light Meter with Silicon Photodiode and Filter

This purchase was required equipment for my husband's work where he will be measuring light at various facilities. Naturally, to get to know the product, it was important to unpack and test it. He did say he felt the instructions could have been more instructive. Upon installing the provided battery, he soon discovered the unit is simple to use.To test the unit he used it in and around our home to gain various readings in different areas. He said it works well. It will measure light from very dim to very bright. It will measure any kind of light. The unit is not heavy, making it easy to carry around. Another handy feature is a built-in memory. It has a large display making it easy to read. Best of all, it works! It will complete the work he is required to accomplish. The unit also comes with a carrying case making it easy to store when not in use.

Incredible

As a light meter it works well. My only issue is the cord really isn't that handy. It is stiff and allows a minimum of movement, and only allows you maybe 10" of range for setting the light receiver away from the unit. You could forcibly stretch it 2 feet or so, but it retracts right back, and pulling it hard enough to stretch it that far makes it feel like you are going to pull the cord out of the receiver or the meter itself. Other than that it does work well and have enough light range for anything I do with it. It feels like it is durable and will last a long time.

Our superintendent Jimmy Hudson loves how it fits compact in his case and how it shows in the dark.

This is something I use in my work. It is a good size to fit in my tool kit, does everything I need it to do. The price was good.

Excelente producto de muy buena calidad y alta precision (calibrado)

The "ON" button sticks and drains battery the battery, if you are careful you can avoid it by fiddling with it so it un-sticks.The other Amprobe (non-LED) light meter I have is the same construction but the button does not stick.So this might just be a batch problem. Until this started it worked fine, meter readings are about 5% different between LED and non-LED meters. Otherwise this review would be 4 or 5 stars.Update:It has not been a problem to check each time I finish using this meter that the button is not stuck 'on', hence I would now rate this 4 star.

I need a good meter and this one gives reading consistantly 25% higher than any other meter we have, it cause us HUGE problems with improper readings !!!! You have been warned.
