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.

Handy tool. Just lacks a timed auto shutoff when there's ambient light. It will turn off if the room is completely dark for a while. I imagine that it's done that way because fine-tuning lighting can be a lengthy affair. I agree with the thinking, but feel like at least turning off after an hour would save some batteries. It would also be great if it was rechargeable.

It seems like it times out at random, between a minute and maybe fifteen? It's super inconsistent which is the most annoying part. Sometimes I can't trust it enough to set it down, walk over to a light switch or DMX control board (for use with theater/concert lighting), and take a reading without it forcing me to walk back and press its button to wake it up. Doesn't matter if it has fresh batteries or anything. And then sometimes it'll give me no issues at all and only turn off when I practically forget about it. It's hardly bad enough that it's unusable, but it's certainly frustrating at times. Other than that, it's great. Don't expect the most accurate colour temperature readings or anything (it bounces around a lot even when you just repeatedly hit the Read button in a fixed scenario) and especially don't put too much stock into the spectrum graph -- it's mostly for show. But I feel I can trust the lux values more than other cheap meters I've used. My other issue is that the beeper is obnoxiously loud. I opened up my unit, lifted the piezo buzzer, and soldered in a resistor to quieten it down. It's really not that bad but I decided on doing it anyhow, and now it's a pleasantly soft beep.

I place this at leaf level and compare the spectrum of my grow lights (leds) set up for my houseplant rack. With the various settings on so many led lights available, this device helps me understand why a begonia does better under one over the other...nerdy? Yup! Goes beyond Lux/Lumens...actually shows a light's strengths and weaknesses...in color...on your phone! Yay! I've had no connectivity issues. It is extremely simple to use and understand. I imagine a colorblind person would find it useful...the graph would show shades of gray and the highs and lows would be just as useful. All-in-all, I would recommend this light testing meter device thingy to my friends and foes. Talk to your plants. :-)

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.

Would not connect to Bluetooth. I literally tried every trick in the book. Defective. It also feels cheap and lightweight. I would pass on this model. There is a reason it is the lowest priced option on Amazon. Very poor build quality but that is the gamble for $35!

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.

Easy to set up and use

可視光のみのLED照明の分光分布に関し、添付画像のグラフのみが表示されます。このグラフの元データである波長ごとの数字データは出力されません。 可視光のみのLED照明ではなく、太陽光を測定した場合は、歪なグラフが表示されます。他の光源では、他レビューにもありますが歪なデータが表示されるため、注意が必要です。 繰り返しとなりますが、可視光のみのLED光源を測定し、グラフ表示のみで良いなら満足する製品と考えます。価格、小型、使いやすさ、が揃っています。

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: AquaHorti Unboxing: 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 artículo 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.

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 🤷‍♂️ 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.
