Flexible LED strips as grow lights?

[Robe]

Hello naoki! Thanks so much for your reply, I've carefully read and ejoyed your threads about DIY LEDs and PAR things. The other contributors and you have answered so many questions in those threads, thank you.

LOL I do need more plants, the whole orchidarium is only few weeks old aaand there's still so much place to fill (but I know it'll end too soon).
I tried to train the little dinos to hunt the evil snails or other pest, if any will appear (hope not), I'll let you know if the training was successful

Well, sure if you're an electronics nerd like us, I guess that's a step beyond the simple LED strip tho.
I will follow you in playing with those very soon I hope

I had read that "6 chips series" but I hadn't been able to figure out what its meaning was. Is my strip a 6 chip type or 5? How can we tell? I can see 3 LEDs per portion and I guess they're connected parallelly together with 2 resistors.

Thanks so much!
Damn I am almost blind but I got the measurements
You were right, we have 3V for each diode and 120mA, so about 0.35W. The resistor here is 24ohm I guess.
How can you estimate the lumens from these data?
