Electrical costs and the little people living in the house have steered me towards led (Trying to minimize risk, speed my current process of slow, and heat would eventually be an issue as all walls are concrete). It's hard to read between the hype of advertising. I've tried to educate myself but lighting, especially led, is complicating to those of us lacking in basic fundamentals of lighting. So when you see these videos of company reps throwing out graph readings of PAR's and lumens and and using a bunch of meter readings to bost their claims, it's easy to get caught up in advertising bullshit. I need a safe, energy efficient grow area - nothing "designer".
