CXA 3070 question

Hey ppls! New here :>
I have minimum knowledge about leds diy etc but I wanna build something in future so I found some CXA 3070 for 30$ each and free shipping. I have like 250$ in my acc and is the only buc I can spend on light!
Buy? Not buy? ...
Thanks!!!

newer model is the CXB3070 BB bin is $36 & rumors of lower on horizon
so imo no

What is horizon?

In the very near future, prices will be lower than $30. That's what he means.

Where did you find these at? Post a link?

The 3500K CXB3070 BB are at Cutter, use CUTANDROLL for a 9% discount.

30.86 USD before discount. The 3000K is slightly dimmer at AD bin.

After doing some reading an investigation on these forums, I've learned that 3500 is a better option than 3000 because 3000 is just the same but without the blue strips. And another person said that 3500 almost isn't efficient enough and should definitely just use 4000 for flower and 6500 or 6000 for veg
