I can count on 1 hand the KZfaqrs with zero bad information. You are THE light guy.

What a great guy doing this for no gain what so ever, just a genuinely helpful post thats cost him time and money. So selfless 🙏 . One of the reasons why i own 5 of his lights, you know you will be looked after 👌

CORRECTION: The conversion factor is off by 1 decimal point e.g. please use 0.025 instead of 0.25. ALSO the 881E model range is 0 to 300,000 lux. Sorry for the confusion. Shane

Wow! I cannot thank you enough. I may now stop trawling the net wading thru crappy stoners waffling on. Perfectly explained the most important thing for any new grower. Get the light right and then match everything to go with it. Fingers crossed.

You are a legend, Shane. Thank you for everything you do!!!!

Great share man! A member of my growing club suggested your channel, very informative and well put together. Keep them coming 🌱📈🌳

you're the man accommodations for people like me i wish i could double thumbs up i appreciate you you are deeply immersed in the field and you dont hoard all the knowledge that you have acquired may the universe bless you immensely! #growlights #par #parsensor #parhack #growboss #legal #legalize #growtent #nutrients #mygrowlights #mygrow #seaofgreen #trellis #rockwool #groworganic #attitude #meter #chillipepper #growpepper #coconutcoir #perlite #foxfarm #growbetter #bestlights #affordablelights

Love it. Shane always bringing the A+

Your service is a gem in the grow light community.

AGAIN Shane you have the best most informative HONEST vids. These days I rarely watch anyone in the scene as im kinda over the greed and cool guy factor of it all as ive become an adult. But I ALWAYS try to catch your vids even if its a topic im totally knowledgable on. The uv vid w the fluorescent bulbs was stellar and informative as hell.

You my friend are a hero. Great work again shane.

You´re a legend! Thank you so much for that Shane!

Lovely work thank you very kindly for your kindness in working on this much appreciated 😘👍🏼

What a great thing to do and share well.done on that one shane..brilliant

Thanks Shane 🙏, my wallet and I both thank you. You are the man bros, much love to you and your company.

That’s dope Shane , much respect and growers love brotha ! 😎🤜🤛😎 Thank you !!

Hi Shane. I've watched your videos for a bit, but I missed this one I guess. AWESOME! Guess who just bought a AP-881E light meter ($25.89) for my 1st ever grow (EST 15 Dec 20) :)

Thank you! I have been looking for this conversion for 2 years on and off.

Sweet, So I'll be using this Lux meter after all! Looks like I bought the same one you have in a video thinking it said PAR somewhere, at 6 am. 😁🤫

Extremely helpful to hobbyists! Thanks!!

Thanks for sharing. Your videos are very helpful and informative. I appreciate your hard work

Thank you Shane you have just saved me hundreds of dollars.

You do not realize how useful this is to me. I buy grow lights to see, since they pants off beat street lighting available for purchase, and worklighting (by miles). This is why I follow you. I do not eat, smoke, or sell plants. Apart from salads as my weight gain junk food habit.

I love you man! Thanks for the work and efford

Perfect! Thanks Shane

DAMMIT SHANE... You rock.. I would buy from you just for the work you do on these vids. TNX

you are amazing cant thank you enough . quality channel all the way

Thank you, Shane. Nice and clever. But even if I measure perfectly, some plants just like more f.e. fert, or light. But excellent to check lamp wear. Thank you for idea.

Thanks for the on point advice Shane.

Thx ,great test,helps out a lot of people!!

Hi Shane, excellent video as always, fairly consistent results across the white LEDs, would be nice to have results for a full spectrum LED like the Lumatek Zeus pro :) of course the light I'm looking to buy lol

This is an amazing video and thank you for doing this! I have that exact Lux meter. So from reading the correction you posted, I am going to take my LUX reading off my 4000K LED white light and multiply by 0.024 as opposed to 0.24, right? THANK YOU! I'm so confused then at why my seedlings are growing so well... my readings, once converted are in the high tens, low twenties at 30cm distance, yet they are growing well. Nevermind!! My numbers are fine. I missed the little "x10" instruction on my instrument. ☺️

Super helpful, thanks!

Thank you Shane! For a quantum LEDs white + far red should i use the same conversion factor as for the white LEDs you give?

Thank you for the tip sir. You da man

Thanks Shane. The AP-881E on amazon goes up to 300,000 lux. The 881D goes up to 400,000. Not sure if you made a mistake or if I'm looking at the wrong products on amazon.

ViparSpectra XS1500 in a 24" x 24" tent. Hanging height about 40cm. I am measuring a max of about 62,000 lux in the center an the nearby areas are measuring about 59,000 lux. Your map for that light shows about 810 PPFD where I am reading 59,000 lux. This light is about 2:1 3000K : 5000K so I would expect the conversion factor to be about 0.022 based on this video, nut comparing my DR Meter Lux Meter to your PAR map gives a conversion closer to 0.014. Using my lux meter and the conversion factors from this video, my whole tent is about 800 PPFD and I am about 1300 PPFD at the center. The XS1500 is closer to 12:6:1 (3000K : 5000: : 660nm ) plus a single IR. Anyway you can compare the XS1500 spectrum with a lux meter and the quantum sensor. I have been dividing lux by 60 (conversion of 0.0167) to get PPFD, but if your conversions are correct I'm closer to 1400 than I am to 1000 at the center of my tent at just under 16". I wonder if the proximity to the row of 660 diodes screws up the lux meter reading. A lighting website gives calculated conversions and it varies greatly when comparing the red to the white leds. Please help if you get some time. I also commented on the XS1500 video because it is a newer one. Thanks for all the great videos!!!

Thanks Shane! About how far from the light source should I take the measurements and could you do a CMH please?

This is so helpful thank you!

Really really helpful. Thank you!

Much appreciated, thank you!

I would just like to point out to anyone using HLG lights, there's somewhat of a difference in this chart and the "chart" that would show up if you used HLG's PPFD calculator. For example, if you're using QB 288 V2 3000k boards, which would technically be 3000k white LEDS, HLG's calculator shows 582 PPFD at 40,000 lux. This chart shows 580 PPFD at around 25,000 lux. Just google "HLG converting Lux to PPFD & Measuring Lux with Smartphone" and you'll find calculators for quantum boards. I've used the HLG calculator for two grows and it hasn't let me down, but I don't have a PAR meter so I don't actually know which chart is more accurate.

Hi Shane, thanks very much for doing this for us poor home growers. Is there a downloadable version of the charts on your website somewhere? I have looked but did not see them.

Great job Shane. Would it make much difference with a ap 881d? Thanks, God Bless and Gods Speed, Geo

Great hack. Appreciate the info👍

if have bought one of these, do i multiply the shown lux reading by 0.026 for hps ? i think thats what it is from your chart

Thank you!

Thanks again for the great information. Would you be able to do a conversion for the Dr. meter Lux meter?

If anyone is using Fluence SPYDR´s PhysioSpec Indoor spectrum is a 4K so you need to multiply by 0,024. this hack is fucking great, thanks guys

Thanx so much Shane. Would different kind of chip (SMD/COB), CRI value and brand productor gives different PAR factor conversion at the same CCD kelvin value acording with your experience? Did you test the same lux meter model from different batches to see actual consistent, if any between two or more instrument? Regards

Can you do a 315 cmh? does the brand affect the numbers? would using two 315 cmh's in a sq meter skew the numbers???????????

Great video as always. Wondering if there is any similar hack but for underwater readings? Obviously that lux meter cannot be put underwater. Thank you.

Are you serious!?! He's done one it again! Thanks champion👍

Hi! Since the spectra are available for most grow light on the manufacturer's website, do you know of a way (a piece of software, maybe?) to extrapolate the conversion factor from an already measured spectrum? Thanks!

Shane - thanks, using your graph, so 30,000 Lux measured on light meter for a 3,000K led is approximately 700 PAR? Seems very decent relatively speaking? With a typical goal for light intensity being 1,000 PAR?

Is it possible the conversion factors are supposed to be one decimal to the left?

Hey, love the channel - when do you expect new lights to come in stock? Interested!

Hi Shane, could you do a conversion for CMH/LEC bulbs of the usual temperatures please? Thank you for this...asked Santa for an Apogee quantum sensor but it appears I've not been good enough in 2019 so something like this is a God-send. Cheers!

Awesome 👏🏻

Amazing, you sir are a genius!

With this meter, am I correct in understanding that you take the reading and then multiply by what number is on the scale just above the reading.?

I'm only seeing an AP-881D that goes up to 400,000 the 881E only goes up to 300,000 is the E version fine or do I purchase the 881D that goes up to 400,000 thank you for all that you do

so if im geting a reading of 65 from the ap-881e lux meter what math do i proceed to do to convert to par.?

Do you have conversion charts for specific lights like say the es 180?? Or mars hydro ts series!

Just got mine. Don't expect super accurate results but with the conversion factor it should put me in the ball park and let me know if I'm improving an area or not.

Shane is so bright and luminous, that no device from apogee can measure it.

that was very helpful thanks a lot.

would this also be accurate if you had red added to your light. For example if the spectrum was 3500K + 660nm ?

Is it possible to do a 6500K conversion? :) thank you!!

Hi Shane, new to your channel, this hack of yours is going to save us a good bit of money, badly needed in confinement. i am using a Fluence Spydr 2i what spectrum would that be?

Thank you so much..... Do you have a . Jpg of the chart to print out? Thanks!!!

Thanks for that info Shane.. I wonder what the conversion factor would be on a multi-colored board, like the ChilLED Logic Puck.. should we just use an average of 3k to 5k values, or would this be too far off?

My man🙌

Hey Shane. Thanks for the work on this. Will the AP-881D work the same as the AP-881E model. Thanks

You are the MAN

Hey have you been able to test something like the Kingbrite 5-bar 600Watt with either epistar 660nm with UV/IR or the new 660nm Cree XP-E2 UV/IR (which is what I have)? Would be great to know if I can just follow your calculations!

total legend mate, what would i use as a multiplyer for a mars ts 1000? or a sf-1000 cheers.

So much good Karma must be going your way Shane! Absolute legend

Could you do 6000K LED? Very common in aqariums

Sorry may I please ask. I have the same lux meter. Because you say "I have calibrated a cheap Amazon Lux meter to a professional PAR sensor, the Apogee SQ500." Can this lux meter be calibrated? I have it but I don't see any calibration instructions.

Hi, is this meter better than "Mini Uni T UT383BT Bluetooth" you made a review on, with 3 other meters so it could be calibrated with the factors you so kindly spent time and made hairs go white to provide us with those factors? Well, as close as possible for white led lights like you said, although some UVs and IRs in the middle, i hope it will be able to make good readings and multiplying by the correct factor...get a PAR reading as close as possible to the Real values. Hope you can get back to me with the answer of wich is closer to the Real values, please! Thank you very much Joaquim

Hi, how many lux do you suggest for veg mode? I just receive my FC3000 and looking at the droopy leaves since I installed it, 30K lux is way too much :)

Ap881 E is replaced by AP881D Does both perform the same , or are they different, i do not have much knowledge about much of the technicalities of light meters

Hey Shane, would that work for my CMH??

Thank you,that is a really big help..I can still test my output without going broke... keep the knowledge flowing my friend..be blessed Adios Amigo

If I have 660nm far red diodes in combination with 3500k white light will my reading be reasonably accurate?

Could you do a calibration for the HLG 320W XL QB V2 R spec LED Kit? thx

@Shane Can you tell me what calculation to use with the Aray2?

So migro I want to ask is anything on the market better than my little 600w parabolic hood growlight with puts out thousands and thousands of lumens with a dimmable ballast

Thanks!

Hallo Shane love what you do on here for us growers I took a picture of you conversion chart but 40000 is where the 30000 wants to be do I pull your blue line with the dots back so it ends at 30000 and not at 40000 ones a gain for what you do for us

Will the 3000k led conversion work on 3000 CMH bulbs. 4000 to 4000 etc.

so how do you read purple LED do u need the 400 piece of kit

is it possible to calibrate it to 40-80 umol/m2/s PPFD (20 umol/ft2/s) and 150-350 umol/m2/s PPFD (50-100 umol/ft2/s) ?

The 1000 PAR reading for HPS is in this chart about 38 000 Lux but in your other hack with the Luxmeter App its much much more .Is there something i didnt get?My mesurements with a luxmeter on a 600 W HPS are much higher too. I get 60 000 to 100 000 Lux above the plants.Confuseing.Greetings Andi

Would you be able to do a video on the Dr.Meter LX1330B . Can’t seem to figure it out 😩😩

I tend to use the RBG SENSOR on my Samsung galaxy smartphone and it breaks down the colors, calculates lux and total white light, go to dialer and input *#0*# and then test sensor which should include the light sensor reading broken down in RED BLUE GREEN LIGHT READINGS. It's nowhere near as accurate in spectrum as an apogee 520 but it still gives a bit of a better average than just the normal lux meter which may not be programmed to differentiate between those colours, so this could work with the blurple leds. Also the lux meters tend to be calibrated for a specific Kelvin and CRI in lighting as they tend to be used in photography and measurements of lumens in interior design lighting.

Hi Shane do you know where I can purchase an apogee anywhere in the uk. Thanks

What about the app Lux Meter? Is it reliable?
