Mine have osram 660, and they stated that on the site.
...i imagine they using Osram Oslon...80?..120?...150?...what model used... any bin?...
...seems to me maybe there are IES Files or other photometric files from Osram....
any IES files + SPD for these lamps?.... (i hear some diferent versions...white +red 660---white +red 660 +fr730 +uv?(osram uv?..))
maybe some day...we have the IES TM25 Files for all grow lamps...or other photometric file diferent than an graphic SPD...
SPD on text helps a lot... IES Files to play with Dialux free soft...
then...graphic SPD ploted on text...+ IES Files....
with the SPD on text...we can use other curious tools...like...

I’ve never understood a single post you’ve ever made since I joined, and probably never will
so my answer is yes. ....mmmm....ok...admito mi mal ingles... algunos ni lo intentan entender...o ponerse en mis zapatos...
what osram oslon 660 are used?... do you know the bin used?... do you know if are a 80º...120º....150º beam angled?
same for other red or violet or uv used... if there are osram...there are some photometric info too... seems to me
maybe better?...sorry my bad english... nothing new for you...
...im dont pretend go against the lamps or your lights...
you dont care tech things...just using...ok bro...no problemo...
...im only trying know better this lamps... normally i try to know all of my lamps...or future lamps...know your poison helps...at least for my pov...
thanks for the... i add more offtopic tipical mine....
curious for side ligth and undercanopy light too...curious cob with onboard ceramic heatsink...
...maybe works with other cobs... ...curious heatsink... plastic its not my preference...but there are curious models on grow lamps.... and yeah not the best leds... and maybe not the best drivers... but its too inspirative for my future diy...

gracias por tu like añado info offtopic tipica mia...
...para temas VPD prefiero los sensirion SHT4x...me parecio ver algun dev board con el SHT41 a bordo...
y para CO2 los SCD41... en espectrometros los V1 ...W1...el dev board... y el del movil de NanoLambda...
y creo nos saldria mas barato y con mejores sensores...pero es diy nivel 2... muchos lo querran de comprar y usar como estos pulse...o similar... no problemo...
su vpd calculator de excel me sirve para construirme una hoja calculadora vpd mia tuneada...a ver si logro hacer un mix de 2 calculadoras de vpd diferentes... cogere cosas de una y de otra.... y sera mas completa y precisa para ciertas cosillas...no llevo prisa... y me puede servir con otras tools en excel... un mix de tools en un mismo libro...con tool de sds de supra de kanna...de...unos cuantos mas ...alguna mia habra tambien... jejejjee...si tuviera mejor pc ...seria mucho mejor...y divertido...pero ya me vendran mejores dias...
Is your Pulse accurate? Why is it reading differently from other sensors? Why is it sometimes the same, and sometimes different?

How to Set the VPD Leaf Temperature Offset
This short guide will teach you the correct way to measure, calculate, and set the VPD leaf temperature offset.
Written by Chris Tosi
Updated over a week ago
The correct
VPD helps plants grow their best. To accurately track the VPD that plants feel, you need to know the temperature at the leaf.
Pulse can take that "
leaf VPD" into account when displaying VPD in the app to guide you to better results.
What you'll need to Get Started
- IR Thermometer Gun
- Notepad
- Pulse App
- Calculator Tool
Calculating the VPD Leaf Temperature Offset
- Make sure Lights are ON and have been for a good amount of time ( > 1 hr)
- Get your IR Thermometer Gun
- Collect 4-6 Temperature Readings of Leaves in the Canopy at various different spots: Top, Bottom, Middle, Sides, etc. Write these down.
- Collect 4-6 Temperature Readings of Non-Plant Material: Supports, Walls, Pots, Plastic, Wood, etc. Write these down.
- Get the Average of the Canopy Plant Temperatures.
- Get the Average of the Non-Plant Temperatures.
- Subtract Non-Plant Temperatures from Canopy Plant Temperatures: (T Canopy) - (T Other) = Leaf Temperature Offset
Ex: Canopy Plant Average Temps 75, Other Average Temps 80
75 - 80 = -5
Ex: Canopy Plant Average Temps, 65, Other Average Temps 60
65 - 60 = 5
- Enter the Leaf Temperature Offset into the App.
1. Log in > go to the dashboard > tap / click on a device > tap / click on the gear icon in the top right > scroll down until you see a section called "VPD Leaf Temperature Offset"
2. Enter the Offset you calculated in step 7, make sure to mind the negative sign if there is one.
3. Tap / click the blue update button.
FAQ
How often should I do this?
- Once a month is sufficient.......MMMMMM.....
Why don't you have a separate VPD leaf temperature offset for night?
- VPD doesn't matter at Night since Plants Close their Stomata.
Where should I measure the leaves?
- All across the canopy - left to right, top to bottom.
...algunos mediremos tambien la temperatura y humedad del suelo de la planta....capacitive soil moisture sensors...
...y la diferencia de temperatura y humedad del aire en exterior al aire en interior....
...y la altura con respecto al mar del cultivo....para corregir el VPD en funcion de la altitud a la que este el cultivo...
