Light Intensity; LED vs HID

Above is reference. As stated inverse square law does not apply with reflectors, lenses and multiple light sources.

This came from a scientist. As I asked one because I thought all the guys that said I was wrong were fucking idiots. Haha

YES IT DOES. It's applied differently in those instances but yes it still applies.

You don't have headlights?

What is wrong with that light? Seems like you have experience and knowledge in this area, thats why I ask.

My back up lights kind of suck after being white light blinded from headlight splash on garage across from mine.

Anyway. I have no knowledge or experience with kessel. How ever I will say that if that light was worth a shit they would brag about the par output and LEDs they use yet they don't so I'd bet my paycheck that it's just another burple BS ploy.....which it reads as such

I was put on to them from my experience using their lights to grow coral. I dont think their horticulture lights are as well known as it seems the LED scene on this side of things seems still fairly new. I know that the lights two modes follow the required spectrum really well and also include UVa.

unfortunately this is the only decent review of these lights I can find. Maybe the info would make more sense to you as when they start talking about specific measurements I tend to get lost.

Compare 90wkessle to 50w cxb3590

To me it looks like they would be fine at 14" spaced every 6" apart. But I sure that would cost a stupid amount of money
 
A good even canopy would seek to block as much light from getting through as possible for maximum photon torpedo absorption. Especially with a trained canopy, I want it absorbing as much energy as possible. All I am concerned with is intense absorption in about a 10" vertical layer.

I'm not sure penetration exists in the sense of an arrow passing through a target but rather how far the bow can cast an arrow across a field maybe.

Get as much green in front of the brightest light.

Saturation is penetration, basically.
