Digital Illuminance Light Meter,0.01~300,000 Measurement Range Lux Meter Foot Candles Luxmeter with 270º Rotated Sensor for Indoor Outdoor Light Meters for Plants (AP-881E)

You can use this Lux meter as a PAR meter for certain lights. Just take the lux reading and for each of the light types listed multiply by the corresponding number : 3000k white LEDs - multiply by 0.023 3500k white LEDs - multiply by 0.022 4000k white LEDs - multiply by 0.024 5000k white LEDs - multiply by 0.02 Metal Halide - multiply by 0.023 High Pressure Sodium - multiply by 0.026 Sorry if your spectrum isn't covered, also this does not work with blurple lights, sorry. Also this only works up to about 900-1000 par.

Excellent switch actuation, and good LCD resolution. Overall good quality. The swivel light receiver is nice but not many people probably use this feature. They could lower the cost a couple sheckles if they designed out the swivel light cup. Meter has good response but I'm not sure of the accuracy without having it calibrated. I think it is accurate enough for my purposes. I do know it has taken the guess work out of setting a light source to "object" distance.

This works well. It’s the only light meter I’ve ever had so I don’t have much to compare it to. However, I bought it in 2020, six years ago, and it still works like the day I got it. My only complaint is that I wish someone who speaks English had written — or at least edited — the English manual. Figuring out what the various settings do is a nightmare, and the manual is nonsensical.

Great Light meter for my plants! I use this to convert over to PPFD to have optimal growth, reference Migro on YouTube. I also use it to manage hot spots and dim areas to get the most out of my lights and electricity.

Wasn't accurate at all and it was difficult to use. I returned it for a refund.

What is there to say? It works, it's fairly inexpensive and it has a little bit more features than the average one in the price range. It has helped me correctly place my lights, I was worried I was giving my plants too much light and this helped me figure out correct placement on them. I am no seeing better growth since I was able to increase the LUX with out going too high.

I saw that it measured Lux, but made the assumption that it would also give me Lumens. Not a light meter expert so you can convert with math I guess, but was looking for something simpler. Toying with the idea of returning it as it's just not user friendly enough for me.

Great for measuring relative brightness of light sources. Swiveling head allows pointing at light source and still being able to read LCD screen. Has a backlight for low-light use. Easy to use controls although the instructions and not wonderful, and contain some errors. Cannot speak for accuracy as that would require a calibrated reference source, which I do not have, but the reading ARE consistent.

Lo uso a nivel aficionado para medir la intensidad de brillo de pantallas LCD de televisores y monitores de ordenador. Antes utilizaba un colorímetro para ese menester. Pero con este luxómetro me evito tener que conectar nada al ordenador ni depender de ningún software. Tan sencillo como plantar el aparato en la pantalla en modo LUX. Y lo que marca el luxómetro es el equivalente a lo que un tele está emitiendo en nits (1 Lux = 1 Nit). El luxómetro viene metido en una práctica funda. La pantalla es retroiluminada en color verde. Hay un botón para activar o desactivar la retroilumación según convenga. También incorpora un termómetro. En una esquina de la pantalla se señala la temperatura ambiente. La célula fotorreceptora se puede rotar 90º en un sentido y 180º en el otro e incluye una tapa protectora para cuando no se esté usando. Por ponerle alguna pena, el compartimento de las pistas requiere de quitar un pequeño tornillo. Tampoco tiene mayor importancia y, ciertamente, es más seguro así. Pero hubiese sido más cómodo no tener que usar ningún destornillador para cambiar las pilas. Lo bueno es que se incluye el destornillador. Compra muy recomendable al precio de 37,99€ que es lo que pagué yo.
