Great meter works ad advertised. used it to check my daughters headlight after dealer said she had no problem it was only out imigiation one light was brighter then the other.We were right so the finally fixed a ground problem. A++
I purchased this product to use on a single lighting job. I have only used the unit a few times but seems to work well. The only thing I have had a little trouble with is the removable sensor wire recoil, after taking the sensor off for the first time the recoil failed. Not a big deal as I just folded the cord back into the unit and it works fine. Otherwise considering the small investment I would give 5 stars.
I'm in the lighting industry so I take fc levels both before and after project installations. This is a great budget meter. I like that it is hand-held and you don't have to deal with a cord if you're just using it at belt height. The retractable cord still allows remote use if necessary, but for my purposes - I don't really need that functionality. I do wish the protector cap that goes over the photo-receiver was tethered somehow. I have to keep track of where I put it when I use the meter...
I bought this meter to check light in various parts of my garden, at different times of day, and during changing weather conditions. If it keeps working the way it currently is, I'll be very happy. The detachable sensor is handy.
This thing is great for the price. Nice build quality, and it works well, it's easy to read and easy to use. There's no way for me to reference the absolute value of the Lumen or Footcandle readings, but the relative readings seem correct. I did a little experiment - I measured 7 GE incandescent bulbs, a 15w, 25w, 40w, 60w, 75w, 100w, and 200w...and the Lumen readings for each bulb were linearly proportional, just like you'd expect.
I got this for checking lighting levels (not photography, but say office, hallway, etc.). It's a great little unit, although a little on the cheap side -- cheap, thin, plastic and so-so fit together parts which probably won't last long but long enough for occasional use. The display is exceptionally big and easy-to-read, and there is an optional back light. Unlike similar, inexpensive products, it does come with a 9V battery so that, when you get it, you can use it right away. It displays a reading about every 1/2 second and is repeatable enough. There are buttons for range and for lux or footcandles, but they don't remember, so you have to do a little series of buttons on each time you turn it on. It defaults to the highest sensitivity which is usually an over-range condition on startup. Overall, I like it, as I didn't want to have a two-handed device with a dangling light meter that requires two hands all the time. Not having to hassle with finding a battery was another plus. The light meter attaches with one of those USB retractable wheels inside the top of the housing and is about 2 feet long.
