Twinstar gline PAR values ?

[Mitelog]

Hi,

I know my request will be tricky but maybe anybody here have a Twinstar light ?

I purchased one in my local store : Twinstar G80+.

I have the photone app on my phone and made some checking with this light but it contain 6 different leds (wrgb) and in the app there is no specific setting for this sort of light.

My question is this : to convert lux into ppfd, there is conversion factor : for exemple, for the Sun, the conversion factor is 54 so if a luxmeter say 30 000 lux with the sun, it convert to approx. 555 PPFD ( the PAR value)

Maybe someone with this light that have a good quantum meter ( apogee) can take some PAR reading at a fixed distance, and do the same at the same distance but with the photone app in lux (with the sun setting or CMH) .

It will give me the conversion factor that i can use myself with a close enough estimation.

If not twinstar, a close wrgb light, but i’m afraid that with the different spectrum, it will be a larger margin of error.

Thank’s for the help

Maybe I’m misunderstanding your question, but my Photone app measures in ppfd. You can select the mode. You do need a diffuser though if using an iphone.

Yes, sorry , i’m french so it maybe hard to understand what i mean.

I know the app measures in ppfd, DLI, kelvin etc… but i want to compare a real quantum meter values , like the apogee ones , against what the photone app say, if you know what i mean ?

As the spectrum of a 6000k white led with a bit of red 660nm led will give very different PAR reading against the 6000k white alone at the same lux reading.

It’s just for me to have an idea
