Over the past few months I've been casually researching LED panels. I've owned an Intelliigent-Gro 540W for almost a year and I've been able to compare it to the 600W hps I used to run. The I-Gro is sorta wiz-bang, with a bunch of leading-edge goodies, including 3-channel timed programmability. You can set time and intensity for Blue, Red and Full. Unfortunately, I don't personally know of anyone whose panel didn't fail. From what I can determine, there are various flaws in the build, one of which is the power supply/driver design. I had two panels fail in less than a year with two different symptoms.
But I wonder what's so hard about designing a robust switchable driver with a decent power supply? Can some of you tech types explain what's so hard about splitting the circuitry so you can time and control 3-4 sets of LEDs? For instance, Far Red is nice to have, but a waste to run all day. Why not split it off to run for an hour at sunrise? Why do I have to run the same Blue intensity throughout my entire bloom? Or even Red? Why can't I custom blend my ratios?
I get that it's expensive and messy to try to run a circuit to each diode, but sheesh, how much more could it cost to split up a couple hundred diodes into 3-4 circuits? And these weak drivers? How much more cost are we talking about? $10? $20?
I dunno. When I see that you can buy standard old-tech panels from a reliable company for less than 60 cents a watt, and new-tech companies are getting $2-3 a watt, I wonder why there isn't room in the budget for smarter drivers.
How much more should it cost to split the circuitry and use robust programmable smart drivers? It's nice to have built-in 730s and/or a 315, but that's not really expensive to add. I've looked at a lot of PAR charts and coverage claims and I don't really see a lot of difference between panels on a PAR/watt basis - some, yes, but not enough to explain the cost. So if they have that much difference in headroom on their manufacturing costs, what's so spendy about programmability?
That would be a huge step, well worth paying 3-4 times as much. And how 'bout WiFi with an app ... maybe a camera in the panel ...
I'd be a lot more interested in that than whatever the latest perfect spectrum might be.
