LUX Meter- What Can I Do With It?

I have some new LED lights I want to try out and have a digital lux meter to play with. What can I use it for, if anything? I have read that a par meter is what should be used, maybe in the future i will get one, but for now i have this lux meter.

Is that a Spider Farmer? This thread may help...

To dial it in and do some math is all it takes for you to convert lux to par (I believe) Take the MFR Par chart.. Hang your light at the distances shown but place your meter in the center where a par meter would be placed. Do all 3 height test and figure out the conversion. (If I haven't smoked my last brain cell that will make sense) lol

Someone on this forum tested a lux meter against a PAR sensor and the lux meter was about 30% off, both sunlight and white leds. It's a useful tool for white leds if you know how wrong your meter is. Otherwise I would advise against trusting the readings completely.

edit: Since you are planning to compare two very similar (I assume) light sources the actual accuracy of the measurement is not important

Slow yellowish growth under vero 29 3000k/3500k

https://imgur.com/a/uLLbG Updated pics, lights on and off with camera flash. Turned down the lights to 200 watts total and they are 22" above the canopy... I wanna say the clone looks slightly better (back right) but the one on the back left is still pretty light colored with some curling...

It's a viparspectra. Looks just like the Mars Hydro and SF updated boards.

I have a Viparspectra Pro Series P2000 and an XS Series X2000. I received the Pro Series first and then relized they have the XS Series, i want to know the difference.

The xs series is 240W vs 200W, has a higher quality driver and more efficient diodes, Samsung LM301B.

I can’t remember where I found this. It was saved in a note. May be helpful. I guess anything over 75,000 lux is beyond the saturation point and can burn. I blur that line myself going higher sometimes and back the light down if necessary.

I'm running CMH and Strip leds for the first time.

Plan to use lux meter for setting led lux via dimmer to match cmh lux, when set at same height.

Waiting for lux meter...

Check out this App called "Korona" I'm not even BS'ing you lol. The app is free for a LUX meter. I paid for the full spectrum LED PAR meter feature. it was $5 and some change.. Where can I go wrong? I tested the par with spider farmers graphs in the booklet and they were pretty spot on. At the least it's entertaining to play around with. It helped me with light placement and usage (Choosing between 3 different light styles and 5 lights total)

Just a look inside for those wondering about it.

Cool for sure.
Dang. Not an iphone in the house. Hopefully Antdroid version soon.

Have you checked the google store?

Hit the link and sign up to be notified. They will let you know when the droid version drops.

Invite someone by that has an iPhone lol ‍
I love cutting corners

Dont think you can get measurements that are worth a shit on android devices which all use a different camera/sensor/whatever. At least iphones use the same technology.

Just download lux light meter... it works

on the diy side...



but maybe we can add UV sensor....


...looking for the plants response to our lights...etc etc..

...the cams way...

on the cams seems to me there are some options on IR cam and UV cam ...the Spectral cams...the MultiSpectra cams....the Thermal cams...

there are other ways to look at the plants response...

...why not add a remote Canopy Leaf Temp (and others sensors too) on a diy grow lamp?...
...when i see some hardwares like down ...i realize mental diy tunning... now its not a gun in my diy mind...


...y sigo aprendiendo de lo industrial y comercial sin comprar ni usar nada...

i like a lot the multi sensor way...on a Mesh net way

i told you Wilson

PD...por tu like Bro C add more pov...



there are others thermal cams to help on LST...leaf surface temp...seems to me more economic on the future...
not included on normal diy lamps but hey... imagine with an small IA for the cam...
its hard to implement a LST sensor or an VPD and Dew Point sensor for an Comercial Grow Light on 2020?...

... ok add quantum sensors are expensive... then maybe add a good lux meter... yeah i know lumens its not the best way but we have some light info to play...Lux ...UV... IR ....Quantum...Thermal sensors for grow lights


...Wilson me pregunto si el sabra calibrar el lux meter?...yo sigo prefiriendo calibrar contra leds o lamparas de confianza... o tener un Dev Board AMS para jugar juasss...

PD 1...por tu like bro Moflow add more pov...

its like an message in a bottle...

On the excel sheet....

Pulse_Labs_VPD_Calculator_and_Chart_Maker.xlsx

on your vpd calculator...

we put the inputs data...
our air temperature
our relative humidity
our leaf temperature

to obtain the outputs data...
our air (and the leaf) vapour pressure deficit (vpd)

sorry im bad on maths...
im missing more outputs data using your spreadsheet...

examples on secondary outputs data....

starting on a knowing VPD "ideal" ...¿its possible Know other "posible" datas?

the air temperature? (knowing VPD + relative humidity + leaf temperature)
the relative humidity? (knowing VPD + air temperature + leaf temperature)
the leaf temperature? (knowing VPD + air temperature + relative humidity)

and others secondary output data like SVP (on air and the leaf)

why not add this "posible" outputs data on your spreadsheet?

i hope you have catch mine idea

Thanks in Advance...

...tu crees que los de Pulsegrow lo veran o lo tomaran en cuenta Wilson?...seguramente no...que pena...
...es que elegimos unas vias de comunicacion equivocadas....manias de un viejo naufrago....sorry...

PD 2....i like the hardware give me some diy ideas too...


...and on the cams way...more comercial info to take ideas for my future diy...

...no llevo prisa... ni doy...


...i told you Wilson... despicable me ...juasss




...Fellas...are you with me?...



Wilson...Minions...back to choza...infusion and vids time...curious seems to me some Bros and Sister dont like mi post...too ocupated... mucho lio.... jejejeje alla ellos Wilson...yo mientras sigo viendo y aprendiendo cosillas interesantes...

paz

Saludos
