Change in Equivalences?

Hi LED Girl, I know I haven't been around for a while, but I keep my eye on your LED stuff cuz I find it really enticing. I could have sworn that like 6 or 7 months ago, when I first stumbled onto your lights it said the 126Watt was equivalent to a 400 Watt HPS and then, when you added the 205 you said it was equal to a 600 Watt HPS. Now your site says they equal a 250 Watt and 400 watt HPS respectively. I'm confused as to what happened. Could you please explain? I was more than a little dismayed to see the product I was interested in buying no longer equivalent to what I thought it had been.

Thanks
SB

Hi SB,

Our equivalencies were previously based on science, comparing the amount of PAR light in the 400-500nm and 600-700nm spectrum from our lights vs those from a HID. We recently changed our equivalencies for two reasons, although our previous ratings still apply for novice or beginner gardeners. These reasons have to do with yield and gardening level, as many individuals have brought to our attention that 1 gram per watt is achievable with HID, and that they achieve it regularly. While we have yet to see any documented proof of this, we acknowledge that the BEST guys out there using HID are likely able to achieve 300-400g using a single 400W HPS. The highest gram per watt rating that has been reported with our lights thus far, is 1.8 grams per watt. I suspect that a pro gardener (as this individual was not a pro) could achieve 2.0 grams per watt or slightly higher with our LED's, meaning the Pro's would need our 205W to match the yield of their 400W HPS.

Beginner or Novice gardeners (the majority of people out there) average .2-.8 grams per watt with HID. For them, our 126W would supply comparable yields to their 400W HID, as beginners with our lights are currently averaging .75-1.0 grams per wattt. Customers who have performed a few grows with our LED's, are reporting 1.1+ grams per watt and are still not considered "Novice" LED growers.

In the end, we'd rather be "understated" with our equivalencies vs overstating the capabilities of our products. Anyhow, that is the reasoning behind the recent change.

The new numbers seem to match what I've seen and experienced.

My first grow with the 126w produced similar to 200w cfl. The 2nd grow was comparable to 300w cfl which I'm guessing produces roughly the same amount as 250w hps.

Gram per watt aside, I'm wondering if the 205w panel will produce the same size colas as a 400w hps. The results I've seen so far are beautiful, potent colas that are closer to the thickness produced by cfl.

Maybe LedGirl can shed some light on my smokey reasoning...

I think it more depends on the grower, strain, and getting the garden dialed in for LED growing. HID farmers have had years to perfect their methods of obtaining large colas, and individuals like myself have achieved those same colas and larger using LED. So far the only results you're seeing on the forums come mostly from people doing their first or second grow ever, who are using our light for the first time. A few journals are experienced growers who are still using a brand new technology for the first time. Give it a few more months and I'm certain you'll see exactly what you're looking for being achieved by those same gardeners with our LED's. By the way, there is 1 member from 420Mag who produced the colas you're talking about with our 126W light. He goes by LevelHead if you wanted to check out his grow from our "See what our customers are doing" thread

Quoted for truth. What LEDGirl stated so eloquently above is what I am trying to get across to people in an alternate forum.
