I wouldn’t use this in a professional quality control setting but for a consumer, it’s perfect.I use it all the time for product reviews and camera lighting.The app seams a little bit underdeveloped but functionally, it works 99% of the time. The 1% is due to some rare connectivity issues that I’ve experienced. To fix it, I just take the battery out, wait 10 seconds, and put it back in.Like I said, this rarely happens though - only two times in the last 50+ times that I’ve used it.Accuracy of color temperature is great as well as the lux reading. Note that lux is not the same as lumens but you can do some quick research to figure out how to calculate that.It is super easy to use. You can press the physical button on the device to take a reading or take a reading remotely from the app.For the money, this is an awesome value for hobbyists and consumers.

This meter works great, pairing was easy and the controls are simple and make sense. Unfortunately, I thought this measured CRI and was designed for slightly different purposes. For photography or grow light measurements, this is perfect. If you're an LED lighting/flashlight enthusiast, go for a different meter.

I got one of these to do a comparison of various lights I have. It is easy to use and gives nice consistent results for light levels. The device is light and small. I feel like it is going to get scratched up so I am going to come up with some sort of case.The spectrum are a bit suspect my opinion. Something I did not pick up before I started using the device and read the instructions (and Amazon description closely), it says "Show the light spectrum of white LED which is generated by the 450nm chip excited by the phosphor luminescence". I can deal with that, it gives a spectrum but then it goes on to say, "...not suitable for white light excited by 420nm chips, nor is it suitable for LED grow lights containing 660nm LED, HPS, CMH, halogen lamps, and fluorescent lamps." Wait a second, how am I supposed to know that the LEDs I am measuring are 450nm not 420nm or something else? I measured in direct sunlight and got a nice high reading, as would be expected, the spectrum looked like I would expect except it showed a big contribution on the blue end, which would not be expected. The reading of an old style incandescent light showed more blue than I would expect. At the office (attached), I measured the spectrum of the long skinny fixture lights that would have been fluorescent in the old days. I believe they are LED but can't quickly prove it one way or the other. Are they 450nm? I am barely certain they are LED and you want me to know what's inside? As I said, it's a good meter but I don't entirely trust any reported spectrum.They indicate the "CCT," presumably the "Correlated color temperature." I measured some LED lights around the house that have published light temperature values and the meter is consistent with all of them. Maybe I was lucky with my choice of LED devices but it looks good in cases like that.I'm not sure why they indicate both LUX and Foot Candles since they the same thing (10.764 LUX is one FC) but then, why not? I have rulers that read both inches and centimeters. Whatever.It is easy to complain. This is a good meter and I expect will prove valuable to me in the future, even if the spectrum might be a off in some cases.

Attempting to see how much blue light is in my life.Only works on 450nm chip, doesn't work with 420nm chips, nor 660nm, which probably include the 670nm and the 850nmFor those of us looking to eliminate the Blue and keep the Red and Near infrared

Works as well as higher priced units.

This is a useful light meter, especially for the price. It was easy to set up, and pairs easily. While there is a learning curve if this is your first time reading meters, this makes the data visual and pretty easy to judge. The app is good. This makes it easy to adjust your lights, and was surprisingly sensitive for the price. It's hard to say how accurate it is without a standard test, but it seems to work well.

On a là un luxmètre, un bon moyen de mesurer la lumière et sa répartition au sein d'une pièce, sur une scène photographique, etc... Tout simple, une boîte sans marque, un petit manuel, deux piles AAA (Même si l'appareil n'en utilise qu'une, ça en fait une pour plus tard), et c'est tout. Le plastique de l'appareil a de bonnes finitions, et ne fait pas cheap avec un effet un peu brossé.L'appareil n'a qu'un unique bouton, et nécessite une application (AquaHorti, peu évocateur) pour accéder aux mesures. Dommage, un petit écran analogique pour indiquer au moins les lux aurait été appréciable. La détection se fait sans problème en autorisant l'application à détecter les objets à proximité, et on peut alors lancer les mesures. L'application n'est pas particulièrement jolie, mais elle suffit.Pour effectuer mon test, j'ai placé le luxmètre à 1m25 d'une ampoule de 8.5 pour 900 lumens (Données constructeur), et j'ai lancé une mesure. Pas de variations, j'obtiens entre 79 et 83 lux, ce qui peut sembler incohérent pour du 900 lumens, on pourrait davantage s'attendre à quelque chose de plus proche de 60-70 lux, mais étant dans une pièce claire, ça ne me semble pas incohérent d'avoir des réflections qui font gonfler un peu le résultat. La température de la couleur de la lumière est elle aussi cohérente, réglant mes ampoules RGB sur un blanc chaud, donc inférieur à 3000K, et on a 2586K ici. La proportion de lumière bleue à 4.53% qui en découle est logique. Je n'aborderait pas les FC (Foot Candle), c'est une unité de mesure plutôt utilisée de l'autre côté de l'atlantique, et on connait la logique des mesures là bas face à un système métrique. Gardez juste à l'esprit que c'est une conversion des Lux, l'application fait juste le calcul à votre place.L'application propose une autre fonctionnalité, qui consiste à créer une "grille", sur laquelle vous pouvez obtenir des mesures point par point (Par défaut, c'est 6 x 6 => 36 points). De cette manière, vous pouvez mesurer en différents endroits d'une pièce, représentée par la grille, la lumière reçue, et donc la répartition de cette dernière. Utile, mais dans mon cas j'avais surtout besoin de mesures ponctuelles. Notez juste que l'application vous sortira une moyenne de toutes les mesures de votre grille, et une exportation des données obtenue.Au final donc, c'est un bon produit. Si vous êtes pointilleux sur l'éclairage de vos pièces, les lumières d'ambiance, etc... Ce sera un bon allié. Dommage comme je l'ai dit qu'il faille obligatoirement utiliser l'application.

Review for: "AH-300 Light Meter,Test LED Spectrum,CCT,LUX,Foot Candle,Blue Light%,LUX Distribution"Brand: AquaHortiUnboxing: The AH-300 light meter came in a small white box 4" x 3 7/16" x 1 1/4" (10.2 cm x 8.8 cm x 3.2 cm) with the user manual and 2 "AAA" batteries (although it only requires one).Operation and App: The app required for the light meter is "AquaHorti" (no reviews yet on the app). The app will use Bluetooth so it will need to be turned on. I had no problems connecting it. Short-press the button on the meter to turn it on, press it again to take a reading, and long-press it to turn the light meter off.Opinion: I ordered this Light Meter to test various lamps I am reviewing, as some are more expensive than others and I was curious why. I don't know much about lighting or colour temperature, but this is a cool gadget with neat graphs. I tested it on a few lights in my home, and a UV flashlight which shows mostly blue light. I can't say how accurate the meter is, but it only works with the app. There is no display on the meter itself, just the sensor and one button to turn it on/off and take the measurement.

La fabricación es china. Se presenta en una austera caja en cuyo interior encontramos el dispositivo envuelto en plástico de burbujas, 2 pilas tipo AAA y una hoja plegada con instrucciones en inglés y alemán, con un código QR para descargar ka correspondiente aplicación.La ficha del artÃculo es muy detallada, tanto a nivel técnico como gráfico, me centraré en aspectos prácticos.La carcasa es de plástico de calidad correcta, mide 6,5 X 6,5 cms. y sólo tiene un botón de función.La representación visual que recoge la aplicación es muy completa, detallada y se presenta de un modo atractivo.Cumple bien con su cometido.

Der gekaufte Artikel ist ungenau. Ich bräuchte ein genaues Profimessgerät.

È uno strumento di misurazione che svolge un unica azione/test: indica lo spettro luminoso delle luci LED - e nello specifico SOLO quelle 450 nanometri - al fine si stabilire la quantità di luce blu presente per capire se l’illuminazione proveniente da una fonte LED nell’ambiente, può essere dannosa o meno per gli occhi.Particolarmente indicato per ambienti aziendali, anche per capire la corretta illuminazione degli spazi lavoro…oppure, in alcuni casi specifici, anche in casa per una corretta illuminazione fredda, dove opportuna.Il funzionamento è estremamente semplice: i risultati dei test è possibile solo attraverso app, anche perchè non è stato inserito alcun display sul piccolo supporto dove è posizionato il sensore di lettura.Funziona con 2 batterie mini stilo (AAA)…e non nego sarebbe stato meglio una fonte ricaricabile via USB 🤷â€â™‚ï¸Piccolo nelle dimensioni, è facile da gestire ed è immediatamente operativo.La misurazione - comparata con altri strumenti certificati - è molto attendibile, a patto di utilizzare come fonte LED a 450nm. Diversamente - il produttore stesso - non da garanzia di affidabilità .Il costo di circa 40€ (al momento di questa recensione) lo pone in linea con altri strumenti di questa categoria, e ritengo abbia un buon rapporto qualità /prezzo.5 stelle perchè è un buon prodotto, seppur semplice, ma realizzato bene.
