Yup, I would take them off and spray the whole unit with conformal silicone, rendering them water impervious, and has good heat transfer. It's got a clear coating, so maybe 1-2% loss, at most, probably less.
Doesn't sound as good to some people, I suspect. Grapefruit is a plus from where I'm standing. Orange and Lemon tones are are cool, but Grapefruit is really getting exotic, I really like the idea actually. But I think I'm an outlier.
Why would wattage have anything to do with penetration? As far as I know, it's an essentially useless number if you have ppfd. Plants don't absorb energy from light. They capture photons and turn it into sugar. I know you know this, but my point is however you get to an intensity at canopy height, that's your intensity at that point. It will degrade over distance at the same rate regardless. The only thing that higher energy diodes might get you is more hotspots.
Because the energy is more focused. Like a garden hose. If you have it set to mist or jet kinda or a flashlight set to wide angle or narrow.
Light all moves at the same speed in this context though. The only thing that matters is photon density and direction. If you are saying the photon density is de facto greater then I guess that makes sense, but then that shows up in ppfd. If you are saying the angle is pointed by a lens at a point beyond the canopy.....honestly I just don't understand what you mean.
No it has to do with direction of the light. You lose alot of light as it spreads. when its more focused then you don't lose as much but also creates hot spots. Bassically the lens is the issue but it goes hand in hand kinda. Higher wattage led tend to have a narrower lens. I think the gavitas are 120 degree? But the closer you get a light the less light is lost overall. If that makes sense.
Yes, that does as it's direction. So essentially you're saying it is not practical to generate enough photon density from smaller diodes when the light is placed higher?
Yes because those smaller diodes usually come along with a wider angle lens
The odd thing I see about this subject is that you see large professional grows with high ceilings running 2 or 3 levels of leds and plants. From my experience there is no way 1 level of 1000 DE's can out perform 2 levels of Fluenc Spyders 2i that are designed for this application.
Was wondering that too and assuming I was missing something so shutting up.
