Okay, anyone heard of this company? Looks interesting, though a working English page would of been nice, I think we can still glean some info. And I believe it's doing that water cooled thing. Crazy kids!

(From Google Translate)

Lemnis Oreon is again succeeded with an LED Grow Light 2.0
to develop more efficient and much more compact than its armature
competitors. In addition to these benefits , this LED lighting particularly effective. That means more micromoles per watt than radiated
conventional lamps. The newest lamps Lemnis Oreon deliver up to 1450 ĩmol and may thus existing Son- T lamps replaced .

Due to the high efficiency LED lamps give off less heat than conventional lighting . The heat generated by the application of integrated
watercooling captured . This raises the possibility to use for heating, immediately or at any other time this energy. Elsewhere

It is well known that plants assimilate better at certain wavelengths in the color spectrum. Lemnis Oreon is able to create exact which are desirable for the growth of the plant . Those wavelengths Thus , there is a combination of different wavelengths used with the focus on the red and blue , wavelengths that matter actually used in the plant. To result in a better quality and quantity.

Benefits Lemnis Oreon Grow Light 2.0

• High light output of 1450 ĩmol
• High efficiency, 35 % more efficient compared to conventional lamps
• Proper light spectrum for maximum photosynthesis
• Reduced light pollution and more light on the plant
• Minimal shading, active water cooling by up to 5x more compact than comparable LED luminaires
• Standard colors are blue and deep red. Other colors are available on request
• Applicable in low greenhouses because of minimal heat

Interesting post here from one of their partners. Some of it's the same old song and dance but there is some interesting stuff.

"NXP Semiconductors and Lemnis Oreon (producer of agro LED lighting) have worked together on significant innovations in LED technology for various forms of horticulture. Most recently they revealed a proto-type of an innovative 600W LED lamp that drives LEDs closer to their maximum capacity without the risk of LED failure. It also allows downsizing of heat-sinks and other cooling arrangements (making lamps smaller and lighter), manages the photon flux precisely (reproducibility) and allows precise and completely flexible control of the color mix (flexibility)."

Does anyone know why there is not one definitive, educational, tutorial, video on how to build a COB grow light setup? I know so many great tips exists here in chat format...Just think it would be awesome to see one epic tutorial video..Then we can make more tutorials when technology advances. So many great ideas get lost in words. We all want to build a COB but don't want to watch a hundred COB vids that are unrelated to what growers would actually like to see. I encourage all to link one comprehensive tutorial or even make a vid yourself. Thank you all.

It's just basic soldering, nothing advanced- and you can even get holders that have 'plug n play' connectors. The details are in choosing a driver and cooling method that maximize efficiency.

epapillon is expanding their CMH line, I never knew they had one
Double 315 bulbs(630) fixture, sounds cool...
http://www.epapillon.com/index.php/products/double-d-papillon
Can't find a price

View attachment 3247351View attachment 3247352

And the also have a single 315 bulb fixture too
http://www.epapillon.com/index.php/products/d-papillon
Only place I can find a price it's 619$

Those efficiency #'s and spd are when those philips bulbs are running vert NOT hort.........................sun systems fixture will beat it at a cheaper price and with a lower lumen depreciation.

epapillion does make nice reflectors though.............pricey

Interesting article at LEDs Magazine with lots of info for the future, especially with the use of flip chips which will probably be coming real soon.

http://www.ledsmagazine.com/articles/print/volume-11/issue-7/features/manufacturing/new-led-architectures-and-phosphor-technologies-lower-costs-and-boost-quality.html

And for those who hate to read it says cheaper, better, simpler. There, don't you feel smarter already? :)

Phosphor pre-formed films

"In one innovative example of new technologies, phosphors are being manufactured into pre-formed polymer film sheets or glass tiles. We will even study the use of optical-ceramic materials that may be applied directly onto the light-emitting surface of LED chips. The promise of these novel manufacturing technologies is to eventually enable wafer-level packaging (WLP) of LED chips. WLP promises to lower chip manufacturing costs by eliminating redundant packaging steps while simultaneously improving LED chip efficacy, reliability, and quality. Ultimately, these technologies, combined with improved manufacturing systems and processes, could lead to the elimination of binning - producing white LED chips with a performance variance within 2 SDCM (standard deviation of color matching or a two-step MacAdam ellipse).

Still in development, these manufacturing techniques are currently being tested on flip-chip LED architectures, where both positive and negative contacts are on the bottom of the chip. Fig. 1 depicts a Samsung flip-chip LED with a uniform light-emitting surface. Samsung announced the architecture in a keynote address at the Strategies in Light 2014 conference.




Figure 1.


Indeed, the flip-chip approach enables a more planar light-emitting surface than the typical wire-bonded lateral chip architecture, providing an easier implementation of the new phosphor-application technique. Furthermore, flip chips are becoming more common in the industry, as even second-tier manufacturing companies have caught on to the benefits they provide and have thus increased their flip-chip manufacturing.


WLP with flip-chip architectures
The most prevalent LED chip architecture in the SSL technology sector today remains the so-called lateral chip structure in which the substrate is at the bottom of the material layer stack that comprises the LED (Fig. 2). Flip chips have many advantages in simplifying design and manufacturing. First, since the electrical contacts are on the bottom, there is no need for the wire-bonds that are required to connect with the electrical contacts on the top of a lateral LED (Fig. 3). This means that you can eliminate a full step in the manufacturing process. Furthermore, wires as a potential failure point are no longer a concern.


FIG. 2. A legacy lateral LED chip architecture has the electrical contacts on top of the layer stack, requiring wire bonds at the package level.




FIG. 3. A flip-chip design implies that the LED is flipped upside down after epitaxial processing with the substrate used as the light-emitting surface and contacts on the bottom being directly accessible to the package.

Flip chips also improve chip efficiency. With the electrical contacts out of the way, more of the chip surface is available to emit light. The entire chip surface becomes a "window" into the light."

flip chip coming real soon!!!

Cree targets luminaire system cost with new XLamp XB-D LED
....

"Like many manufacturers of lighting-class LEDs, Cree uses a flip-chip approach in which the substrate side of the die is on the top side of the packaged LED. Scheidt said SiC offers a refractive index that better matches the GaN layers than does sapphire, thereby improving light extraction."
