Well said 707, but If you look at any photosynthesis graph you will notice the blue is actually higher than the red. Yes, I do agree that maybe a little more red in the 660-670nm range would be "ideal" color for flower, but we're not that far off at all. Maybe we'll offer that for the next generation of our horticulture LED. It's an ongoing process for us to perfect our LED's. It's also very costly to do R&D and the time involved.
I've personally tested one single source led all the way up to four chips on a fixture. Yes, you may have a little better area coverage but you are loosing the punch power when you lower the wattage on the chip. It could be as much as 30% less punch depending not he chip. We're trying to perfect the ideal punch vs area coverage. What we specialized in is high powered single source full spectrum COB. We don't want our led to be like the China made chip with a bunch of 3-5w and put it in a fixture. That's why they give LED a bad name for the horticulture industry in the past. It's gotten better but they're not there yet. We're here to change that mindset, one grower at a time, one industry at a time. Slowly but surely!
There's a lot more exciting things to come in the near future. Just keep an eye our for us.
