Guys, please...

Look, BigBlock has his view, and other have theirs...

More friendly guys! If this guy bought the LED lights, lets see his grow... let's give it a chance...

If at the end BigBlock was right, well, good! If he was wrong, good as well!

The way I see it, the hobby is all about experimenting... Of course, you use the experience from others... but, I think experimentation is key.

Let's see how the LED grow goes!

Hey BigBlock,

You're a Lighting Engineer... right? Well, question: Why the hell can't lumens be added up?

From what I understand, if I have two 1000 lumens bulbs, I'll have... 1,000 lumens... not 2,000... no... 1,000.... why?

I'm pretty technically/chemically/physically/stonedlly inclined, so please feel free to use terms and concepts... but I still don't get it... why? 1 + 1 = 1?
turtle420 Reviewed by turtle420 on . About those LED lights I was reading that in order to equal one decent HID light, you need a panel of like 52 LED grow bars. One LED grow bar goes for $150, so that's $7800 vs like $300 for the HID. You do get greater bulb life, but 52 led bars, with three light clusters per bar, is going to take up quite a lot of space, so there's absolutely no real advantage. So don't waste your money on LEDs.
