Pretty useful tool 
Calibrated, picked my blue/red LED (blurple), and according to that they’re falling perfectly within range of DLI for the Olsen Twins (which i could tell by how nicely and uniformly they’re budding out but it’s nice to have an actual “figure” to measure )

Just want to give the most updated table I’m finding that is working.
Here I have raised DLI earlier on, to avoid the excessive stretch of autoflowers or short veg grows while dropping it in the last 2 final weeks to avoid fox tails.
I would like to update this post with the information @BobbyDigital and @Hellraiser were able to confirm as well as others now that we have an accurate app that we can rely on.
Not sure if that’s an ability that can be granted @BobbyDigital?
Worst case maybe I can type it out and you can copy paste it into the original posting.

The only lux to ppfd calculator I can find with close to matching spectrum is for cree 3k. Will that suffice for my qb120s in 3k?
What I’ve figured so far with that calc is that I need to be around 17k lux for the correct ppfd to achieve correct dli. Whata mouth full!
Am I headed down the right road?
So calc I found today says I need around 25k lux to be where I want.
Sorry for tripin, this new light has me stressed to the gills. Years of holding my hand at canopy top does no good here.
Maybe I’m just over complicating this cuz I ain’t got it yet. Need that ole bulb to light up so I can say, ureka🙃

We have found the photone app with a regular piece of printer paper used as a light diffuser works the best when set on natural sunlight.

Yhup, I’ve been following this page for a bit. App doesn’t work on my phone.
App does work on my woman’s but I don’t want to bother her with that.
Bought a lux meter. Found everything says you can’t convert lux to ppfd without knowing specifics about the light. My boards qb120 3k doesn’t have any specs on the page besides the above mentioned.
This is my 1st led light and I’m lost af. Was thinking today about busting out the hps to get these girls up to the net.
The closet I can find I think is low cree led, long day and I’m not remembering right. I’ll look back at what I’m needing in the morn.

If I gotta go with her phone so be it. Just trying not to bug her, buy a new phone or spend a ton of money. Thanks @Nicky for your help.

Who made your QB?
If hlg did they have their own lux to PPFD conversion (google it).
Otherwise it should be all examined above.
Waveform lighting has the converter I use.

Ok waveform was one I was working with.
Back to my question, which spectrum do I select from the drop down menu?
Trust me if I could figure this out i wouldn’t be here asking. I research my ass off b4 I bother anyone. I’m not here asking bs question, I’m lost.
You dug this rabbit hole and lead us down it, now needing some help.
Riddle me this and I’ll be off this thread.

Ok with those 2 options I get…
Hlg= 364 ppfd
Wave= 475 ppfd
That’s why I’m lost.
