Please don't take this the wrong way, I'm not trying to be a D-Bag but,
The new Vipars were built to suit specific areas; 2'x2', 2'x3', 3'x3' and 4'x4'
"first off Apache uses no 660nm."
Area 51 SGS-160 has no 660 diodes and they work just fine.
Apaches can be had for $750.00 + shipping with the code found in Tags420's posts.
ellydee, have you ever built a light, planned the whole process from beginning to end, sized everything for max efficiency, planned every chip placement, thought one what power wattage, lens / reflectors .... ?
I can tell you without knowing much, or being a light builder / designer, these are built on the idea to suit a happy medium. well first there copies of the famous HGL design. second, as I said in the beginning, if you ever built / designed a light, you would not build what they offer. you don't build a 20 inch panel to cover 4x4 area... the design already speaks to have low intensity sides , with high intensity center.. that was there brilliant design team idea from the beginning??? I'll give you a hint what it should more look like ( long, spread out, ) .. to me it's personally the downfall of LED, the design required to make them very efficient, these can't be built pumping out 330 watts in a small box, it doesn't work that way with LED for max efficiency ( once again not disputing they don't work, they do work ) . if we keep the same design, yes you can have that in 10-15 years with very very high intensity, but it's the wrong thought process to have.. I once had a talk with someone about managing money, I told them " if you can't learn to manage what you have, in the future, it will be no different then now.. or you can learn to manage what you have now, so whatever you have in the future you will be successful in managing.. " success doesn't come by throwing more of whatever you have at it, it's about truly thinking out the end goal and working back from that.. ( it's like the principle of cars, throwing more horsepower doesn't make a car faster, what makes a car faster for far easier.. weight reduction ) ( if you know what your end goal is, you know the steps your taking are the right or wrong ones )
I'm not disputing if they grow. any panel does, but not with efficiency, and even coverage which can be better had with LED then any other system, as the uses of many many LED make that possible.
the 660nm comment was for the person talking about apache, as I was trying to say, you can't compare a panel using ( IDK, 640nm ? ) to 660nm... as I always say, you can never truly compare anything
you can choose to think I'm talking horse shit, or do whatever you want with my words.. there one opinion among a sea of them..
