Lighting mystery

I have 2 lights I just bought. One I’m sure is a pos so I bought another one. The first one I guess is what everyone calls a “burple” light. So I took my light meter and this is the result. The mystery is, why is the ppfd higher with one light than 2? Or is the “burple” light interfering with the reading on the meter?

Hey Buddy, what APP are you using to take the readings?


It’s on my iPhone 13 Pro Max.

Oh yeah. I had that one but it cost money. Lol. Being sick Has almost broke me so it has to be free right now. Lol if you get a min compare the readings on the two and see how close.

That is light color 3k or 4k not power.
Ppfd is the power! You have more ppfd with 2 lights on but different color
