I don't usually buy products that haven't been reviewed but in this case, the product looked good for the price and I decided someone had to go first. I am quite pleased with my purchase. This meter arrived in excellent condition. Of course I would expect that but other product have had blemishes or scratches. Features I like in this over less expensive meters are additional buttons so that I can get to the functionally more directly. I can toggle between min and max readings that are saved until cleared. Another feature this has is a relative setting to compare brightness to a baseline. It can also be re-calibrated. It is responsive and the bar graph is a bonus. As for accuracy, I compared it to two other meters and at around 500 lux, they were all within 10 lux of each other. This meter is more tolerant of variations in aiming and handling multiple light sources. It includes a soft case with a pouch for the manual. It is a nice upgrade from the common less expensive meters.
For the price this meter works great. It's helped me nail down the correct sunscreen for my plants taking the guess work out of it. As for measuring LED lighting, contrary to one question answered the description does not mention LED's and I question the low reading I get from my 1200 watt unit since I need to wear sun glasses due to the brightness. It's a good "light" meter (except LED's) but it's not a PAR meter.
Readings, if you can even call them that, where virtually unchartible. At the lowest setting it maxes out at some nebulous number of 19.46... ok so you step that up to the next reading and get a zero value. Messy - unreadable beyond half an arm length because the lcd display fades out beyond your vision.
Excellent for the money. I use it to triple check lux settings with 2 other meters. (Seems quite accurate, although there will always be a bit of difference out and about when measuring nights at night due to traffic variations etc.)
Great product for light study
For an inexpensive light meter, this one works well.
produces good data for customers
This model is probably one of the most affordable lux-meters in the market.
