**UPDATE 04/18/2017**
Hey there ICMag!

As 4/20 approaches, we want to thank everyone here for your support of our new URSA Optilux launch! We have gotten amazing feedback and a positive reception from all you guys here on the forums. We’d like to extend a special thanks to those of you who have ventured out to our Fremont office and toured our facility. Always happy to meet you guys face-to-face and talk grow!

Since the launch, we’ve gotten so many requests to bring back our pre-sale pricing, so we’re excited to announce today…

URSA LED’s 4/20 SALE!!

For the next week following 4/20 we will be bringing back our pre-sale pricing of $1,200 for our Optilux fixture as a thank you to everyone who supported us, and for all those who have been waiting to try out the Optilux but could not fit it into their budget!

ADDITIONALLY! We will be selling our Helios 185W and Helios 320W fixtures in our DUET spectrum for only $215 and $370 respectively.

At URSA, we like to keep it simple. Just mention ICMAG in your inquiry and we’ll automatically include the promotional pricing. Please direct any inquiries to sales@ursaled.com or PM us!


The next stage of LED lighting. Designed and built in the USA.
We've taken our experience and lessons learnt and took every flaw in the LED industry, and we've created something special. Introducing, the world's most efficient grow light, the Optilux16.

The Optilux16 is a 640 actual wattage draw fixture - that produces a stunning 3.5+ PPF/W (pending lab report). It's incredibly under driven to the point that it's almost reaching the absolute curve. URSA's team contains 4 PHD engineers that specialize in horticulture spectrum control. Our full spectrum is different, because we build our own chips. URSA only uses BLUE LED chips, and converts the blue light via a layer of in-house phosphor, specially formulated to provide CANNABIS its 8-10 photosynthetic peaks that it needs. Additionally, our spectrum contains a small percentage of UV down to 350nm, and far red up to 780nm. It is great for vegging, and flowering.


@KRUNCHBUBBLE has noticed the following while under URSA Spectrum;

1. Reduced Vertical Node Stretching
What this means, is your nodes stack a lot more, which means your production, yield is increased while maintaining the same vertical grow space.
2. Increased Node Strength
3. Increased Leaf-to-Stem Strength (tensile)
4. Increased Vegetation Speed
5. Increased Canopy Penetration (advantage of COB LED)
6. Significantly Increased Sugar Content Production.
7. 1400 BTU Per Fixture
8. 30% ADDITIONAL LIGHT THAN THE 1000W HPS Fixture using only 640 WATTS. (feel free to come down to our office and measure the PPF efficiency yourself).


*edit 12/24: Yes, the bracket can be removed if you use the wires on the sides. And yes, the wires can be removed, so you can use either or, or both.

Nice unit, are the production pieces any different from the renders, i wonder

The last time I commented on what I thought was a misleading and overly commercial post it turned out the OP had paid money and was a sponsor now.

I will stay out of this for the most part, assuming some of those familiar with the COB lights already available will do some direct comparisons. Amare comes to mind.

I do have to comment that 450 nm is nowhere near UV, nor do phosphors convert to higher frequency, only lower.
A pet peeve of mine is salesmen paraphrasing science, the rephrased facts are invariably inaccurate due to their lack of being understood.

450 nm is near UV, lol.

Referring to Stokes shift, which describes the change of
wavelength of light from shorter to longer wavelengths.

Additional heat being the result.

I don't have a horse in this race, and my talents and expertise
do not include phosphor-based LED technology.

Hopefully this thread will get some direct feedback from krunchbubble
experience with these lamps.

I'm thinking he meant to say 350nm, but i agree that it does sound highly paraphrased and not that great convincing to have me wanting to try this product out. I will wait till other people get their hands on this product and see how it performs for them.

I'm sorry guys... I meant to say 350nm

The thing about Amare is... and pretty much all other LED companies out there... is that they use the same chip makers... CREE.... PHILIPS... SAMSUNG... OSRAM... etc... and they are made for general lighting. The phosphor conversion or RGB chip they use, was meant for general lighting. So now, you have all these LED companies trying to mix different chips together to create a blend of "Spectrums" they think works... but in fact... those chips were not meant for plant grow.. but yeah.. they "work".

Look at our spectrum that shoots into deep red, and also check out our R9 ratings for our phosphor in our high CRI series. Our materials science division in phosphor and bonding processes are #1 in the world. I wish I could tell you more about our OEM customers...

What will the coverage area be. Was about to push the button on 4 of your 320s for a 5x5 tent. Now another choice to make.

[zachrockbadenof]

we use '4' 1000watters... so if I 'presume' I need the same '4' fixtures over the same area, I'm paying 4800bucks, against say 1000bucks for '4' hps's... 3800bucks pays for a lot of con ed...

[FunkBomb]

Do you have any information about the size of the unit? Do you have any light measurement readings for a 4x4 or 5x5 area? That spectrum does look very nice as well as the 5 year warranty.
