I get that what you are saying and you are indeed very right,
All I’m saying Is the concept sound good on paper, but in reality even with 300 opposing angles which some of them might or might not hit the canopy straight from above or the sides of the buds is not adding much credit to their initial output, which is low to begin with.
So yeah your concept is spot on but lacks the proper 300 opposing high intensity lights to go along with it. they are still too low output to use these concepts and light angles in a proper way, unless people want their plants to hug theIt fixtures sort of speak
LEDs, because of this, have a hard time when being confronted with long distances and canopy depth
Still not a very good solution although in the future when they stick much higher voltage diodes in their fixtures I think we will see massive improvements.
i feel as if maybe you don’t have experience with different led tech apart from maybe the ones ur using now. Let me break abit down for you see if we can find some common ground on which to agree.
Imagine each of these scenarios in a 1.5x1.5m tent
Hopefully we can both ignore infra red radiation for the sake of this chat.
1 x de 1000w hid
Needs to be hung at around 1m from canopy depending on reflector for 1 main reason uniformity.
This light will produce the highest output per source (imagine integrated sphere) which has the potential to penetrate the furthest if unobstructed
If hung closer to canopy the light will not reach the corners at the intensity we desire and we will have too great a hot spot in the centre. On the flip side depending on our personal circumstances and the dimensions of our space, this may be a good thing. We might want space to work, space to spray plants without risk of bursting a bulb, space for air to move or for other equipment to be placed around the edges of our grow, the list goes on
4 x se 250w hid
IME needs to be about 20cm from canopy depending on reflector. Lacks the initial output at source vs the 1000 but makes up for it cos it’s placed closer to the canopy. Multiple lamps mean multiple angles of incidence which means otherwise shaded budsites under a 1000 are lit by unobstructed light coming from more angles thanks to the 4 lamp set up. Also they will light the canopy more uniformly than the 1000 which goes without Saying. However the value at 1m away from the lamp will be significantly lower than the value at same distance from a 1000
9 x 70w cob
Now we need to take into account the lens and angle of light distribution (the cone), because of this most of these are designed to be hung higher than most other leds, because they behave kind of like a single source (not technically though), these leds are probably the closest comparison to traditional hid lighting. But because there are more sources they light the canopy more uniformly and also the plants will benefit (to a lesser extent than the 4 250s due to the light cone) from the multiple angles of incidence.
2 x 315w quantum board fixtures
These lights can be hung closer than the cobs and this light will spread out many lower power sources over a greater area. Increasing the number of angles of incidence, thus increasing the ammount of photons that hit said bud, branch, leaf whatever vs if all photons came from same source and hit various obstacles on route.
1 x 630w strip/rail type fixture
Now these fixtures usually have the lowest output per source OR the same as a qb but more spread out. The aim of these fixtures is to provide the ultimate uniformity of light intensity across a 2d plane, this means they need to be placed rather close to the canopy to maintain the same intensity at the top of canopy. And because their diodes are spread much further apart the plant can benefit from photons passing more obstacles on their way to said point instead of having to “push through” vegetation.
please bare in mind that the fixtures input wattage may vary from manufacturer to manufacturer country To country and in no way do I stand behind the numbers as a rule of thumb, we can’t compare dimlux with phtontek or Mars with agentIx here.
hopefully we can find some ground on which all of us can agree
