Did you have to calibrate it ? And also have you compared the PAR readings to another PAR meter ?With my Smat Farm lights mounted 8" above my tank,
running the 6 channels at 10/60/60/60/10/10, at the water surface I got:
full spectrum 445 ppfd
white blue spectrum 645 ppfd
12 hr DLI = 18.1
Did not do any underwater measurements.
no and no.Did you have to calibrate it ? And also have you compared the PAR readings to another PAR meter ?
If you go to there site they have some great you tubes on the comparison and even between iPhone and Android ….I posted earlier, but here are my results at my water surface, about 8" below my lights.
Smat Farm lights
Running 10/70/70/70/10/15
Using full spectrum resulted in lower PAR/DLI numbers.
Using the white blue spectrum, the resulting PAR and DLI were higher.
Cool app but with so much uncertainty over which spectrum to use I'm having trouble actually putting these results to any use.
I've gone over the website can't still can't seem to figure this out...... below is what the site says as far as LED source settings..... I couldn't find any videos that dealt with this.If you go to there site they have some great you tubes on the comparison and even between iPhone and Android ….
They also have the specs on which spectrum to use for what leds
I'm in contact with there support as well, I will forward this to them ...I've gone over the website can't still can't seem to figure this out...... below is what the site says as far as LED source settings..... I couldn't find any videos that dealt with this.
Which LED setting do I need?
If your LED grow light contains only a few or no white LED chips and looks purple, use the LED red / blue setting. If your grow light contains mostly white LED chips and looks white or yellow-ish, use the LED full spectrum setting. If your light is mostly blue, use the LED blue / white setting.
LED Grow Lights
If your LED grow light contains only a few or no white LED chips and looks purple, use the LED red / blue setting. If your grow light contains mostly white LED chips and looks white or yellow-ish, use the LED full spectrum setting. Some LED lights that require the LED full spectrum setting might include pure red, pure blue, ultra-violet (UV) and infra-red (IR) chips as well. If your light is mostly blue, use the LED blue / white setting.
So if I'm trying to measure a light that uses a "puck array" style led like the Smat Farm or Noopsyche V3, I'm guessing I use full spectrum??? These lights have 6 channels. below are the channels and what % I'm running them now..
(these are new lights, so I'm in the process of ramping them up slowly)
10% CH1: 14000K Cool White
70% CH2: Royal Blue(450nm), Blue(470nm)
70% CH3: Violet Blue(430nm), (470nm)
70% CH4: Violet (420nm), Violet(410nm)
10% CH5: 3000K warm white
15% CH6: 500nm green
So basically I'm running my blues at 70%, 10% whites, 15% green. So blue/white then???
I sent their support an email. Maybe they can give me some suggestions.
I do understand your concern, but for what is used for maybe once a year if that. I do it in the Air, but if I would to do it in the water I would definitely vacuum seal it and then dunk it. I have tested it, and also if you have a oldr phone you no longer use would be a great option. But I do understand your concern.This app has been fun to play with in the air, but I think I would rater use a dedicated PAR meter built for use in water before I intentionally plunge my phone into saltwater. Sure it would probably be fine. It would cost alot more to replace the phone when it dies from saltwater exposure then just buying the PAR meter in the first place. Just my thoughts.

The app suggests using the front camera to assist with aiming towards the light source. I don't think front cameras have really changed much in the last few years to make much of an impact. But I am no expert. Good question for sure.Regarding using old phones.....
Anyone think that quality of lens and camera on phone have significant impact on readings?
Surely placing a film over the lens will skew results potentially significantlyVacuum sealing is a smart idea.
Valid point. I'll stick with the stick.Surely placing a film over the lens will skew results potentially significantly
