Sale!





NeoSol NS LED Grow Light

$1,365.00$548.00
The NeoSol™ NS grow light is suitable for a wide range of horticulture lighting applications including propagation of vegetative or flowering plants in grow tents and compact growing areas or large-scale commercial grow operations. May be used in vertically stacked orientation of two or more layers of grow trays and NeoSol fixtures. Equivalent to 600W HID performance in a 3×3 grow bed, giving growers more than 50% energy savings.


came across this 60% off deal, i don't know shit about em, but seemed like a good deal if it's an ok light. sorry to jump in your thread.
WTF is that? Did you know Disco is dead?

I like the design work.

If we go on the assumption that the bins listed in the Cree PDF will all become available, and that those are the best that ever will be available, then yes the 90 CRi would be the best bet. That said I do not think the 90 CRi phosphors are more efficient, more likely the bins listed were chosen arbitrarily, maybe chosen in error. But if I am wrong, that would be awesome :)
Ok, so to recap with what you typed (because I sometimes get lost reading your thoughts), you believe 90CRI Cree COBS are a better alternative in comparison to 80 and 70 CRI due to more deep red, despite the lower efficiency. Wait, are you not favoring efficiency in this case?!?!

This cannot be... you are SupraSPL... efficiency is God... for you..

:wall:

o_O

:lol:

Also, I was catching up on your math earlier and I couldn't help but notice how lenses and reflectors are ultimately prone to losing light, regardless of the gain of concentrating photons. Do you see this as a reason to NOT use reflectors and lenses or do you believe, with your experience, that there is a legitimate and productive reason behind doing so?

You are right, I am almost always in favor of higher efficiency over better spectrum, especially when it is a small difference in CRi. What I am saying is that IF a top bin 90 CRi was made available (as listed in the current CXB3070 and CXB3590 PDFs) and assuming they don't release new top bins for the 80 CRi, then technically the 90 CRi would be higher efficiency than the 90 CRi.


All that said, that may not reflect reality, it may be because of arbitrarily chosen bins listed in the PDF.

-In the past Cree released new top bins for the CXA3070. It used to be Z4, then they added AB, now they have added AD.
-In the past top bin CXAs never became available they were just on paper
-80 CRi phosphor is probably more efficient overall because it is closer to the blue of the original die. For example if the very best blues were used, the 90 CRi would not be the most efficient outcome in terms of photons, PAR W or lumens.

For example if you look at the CXB2530 the 3000K top bin 90 CRi is still 2 bins beneath the top bin 80 CRi until you go up to 4000K.

Sorry OP, just realized how far off track we got

Fucking bins, always complicating matters!!

:wall:

Thank you for the clarification, Supra. Is it possible for me to find the answer to my last question on a different thread?

:confused:

2 step and 4 step don't really have any differences unless you're an interior designer and "can tell" that the lamps look slightly different in tinge. In reality, 4-step is just fine, and if 2-step costs 1 penny more, it's not worth it (even for interior design).

Yep. $3 a pop...he even said if that was a bad price we could negotiate... I laughed to myself and gladly gave jerry $3 a piece. Some places in the us are charging upwards of $20 for these things! :o I see Newark has them for 2.68 but jerry threw them in my order so I don't mind paying an extra $6 total. Lead time from jerry will be a few weeks , waiting on the 5000k anyway so no rush. Good things come to those who wait!

I will do some experimenting with the lenses...maybe just put them on the cobs I mount to the perimeter. I have read good things a bad things about the lenses. I think that they are worth it, just to have the cobs protected from the moisture and dirt of the room, and for ease of cleaning, I can just wipe em down.

So I've decided on my heatsink.

12" x 32" x2
5 cobs per HS
Total dissipation 377.7w each
Which gives me a static air temp c/w/3" of 35.4C. I expect this number to come to exponentially because I will be actively cooling the sinks, but if the fans die it won't fry my cobs
Thank you @REALSTYLES I like your setup, puts my mind at ease about mounting so many cobs to one sink. The looks great suspended above the girls! What kind of yeilds are you getting with those? Actually I'd love to hear about your whole setup. Ventilation, grow medium, strains, nutes, etc!

I am going to use a homemade DWC/drip system (tried and true) and a classic strain of a good balance between yeild and quality, probably white widow. Hoping for at least 1.5g/w.

Also, any suggestions for a seed bank that relievers to a non friendly state? Last time I ordered it was from Marc Emery (sensi seeds)in 2000. I have had a few people tell me that their quality has declined and not worth the huge price tag they carry. I've been reading the see bank forum but there's so much to sort through and so many breeders I've never heard of.

Easy fellas...
@brimck325 most of the prefab led arrays are over priced and underpowered. I've done a lot of research, seems that DiY with cobs is the way to go. Do you have some specs for that light you posted?
