Not good less than 150lm/w. I wouldn't show this to my worst enemy. That mixed with the output being garbage... Ill stick with 2.1umol/J
Don't tell me, talk to CREE :). And how do you KNOW it won't grow great? I think it's fascinating that CREE has finally gotten into horti. 130lm/per watts or less can grow some great weed from what I've seen and smoked. Personally all this performance talk reminds me of geeks and their video cards talking abourt Winmarks or whatever it was instead of how much fun the game is. But that's just me I guess.

And for people who are "into" LEDs and not just brands I offer some more bold claims and info from you know who and their weakass LED grow lights :P.

Cree’s new XLamp® XP-E & XQ-E High Efficiency (HE) Photo Red LEDs deliver up to 21% higher output than the previous generations of XQ-E and XP-E Photo Red LEDs, enabling horticulture lighting manufacturers to deliver higher performance products, reduce luminaire size and lower system cost. The XP-E HE Photo Red LED is the first photo red LED to break the 1 W radiant flux barrier at 85°C, while the XQ-E HE Photo Red delivers over twice the PPF output per area compared to the closest competitor.


“The XQ-E family provides a unique combination of ultra-compact package, high output and wide range of horticulture-optimized colors,” said Michael Naish, director, Rusalox. “Using XQ-E LEDs with our unique AlumOxide technology, our customers can create luminaires that use half the power of conventional HPS luminaires, as well as being smaller and weighing less than incumbent technologies. The higher performing XQ-E High Efficiency Photo Red LED will enable customers to quickly reduce the power consumption of their current design even further for faster payback periods.”

The XQ-E High Efficiency Photo Red LED sets a new performance benchmark by delivering Photosynthetic Photon Flux (PPF) levels up to 5.39 μmol/sec at 85°C from a package footprint of just 1.6 x 1.6 mm. The new XQ-E’s ratio of output to size is more than double that of the closest competitor. The XP-E High Efficiency Photo Red LED delivers up to 6.08 μmol/sec PPF output at 85 C and is the first LED to break the 1 W radiant flux barrier at 85°C.

“The new XQ-E and XP-E High Efficiency Photo Red LEDs bring Cree’s latest high-power performance breakthroughs to horticulture lighting, with twice the PPF density and higher output than all other available LEDs,” said Dave Emerson, vice president and general manager for Cree LEDs. “Our technology enables customers to create high performance, long-life luminaires that drive the adoption of LEDs in this emerging application. With these additions, Cree continues to offer the industry’s best portfolio of LEDs optimized for horticulture, including White, Royal Blue and Far Red color options.”

Both XQ and XP LEDs for horticulture are built on Cree’s ceramic high-power technology that can deliver R90 lifetimes over 100,000 hours, even at the extreme temperature of 105°C. In addition, horticulture lighting manufacturers can immediately take advantage of the existing ecosystem of drivers and optics proven to work with the XQ and XP platforms to accelerate their time to market.

Product samples of the new XQ-E and XP-E High Efficiency Photo Red LEDs are available now and production quantities are available with standard lead times.

I use chain. Don't trust other people's crimp connections! And I add a safety chain too after having a rope ratchet fail, dropping a large light and squash a plant flat...........
Crazy! I was staring at a full 5gsllon bucket I use in gravity watering saying, if that thing fell I'd be screwed.

nice but why bother with discrete chips? COBs are easier to work with and the newest generations from Citizen, Cree and Bridgelux are very efficient even when driven at 100 watts per COB. Hell, anyone could build a COB based light in two hours, even with building a frame.

Amare has some nice gear. But so do several RIU vendors. Anyone wanting a light and no DIY, should start there, and at least look around.

And although Cree builds good chips, they are way over priced vs output when a $12 Citizen chip comes withing 8% of Cree's top bin COB that sells for $45

Cree no longer is King, but they still get royal prices that's all! I'd consider Cree COBs if they were to start competitive pricing. They've owned the market so long, they don't believe they even have competitors!

All this Cree talk is probably killing sixstring. We both know citizen is the best.

Reflow soldering is probably what will prevent cobs from ever taking over greenhouse lights.

For mass production, reflow soldering is simpler than screwing on cobs + heatpaste

Well then how bout this? BTW do you have some best? Please show me some best so I can be impressed. LOL :roll:


And now back to greedy companies and their poorly designed, inadequately engineered and woefully unimpressive lighting.

Philips Lighting, a global leader in lighting, announced the launch of the Philips GreenPower LED flowering lamp 2.0, an even more energy efficient way to extend daylight or interrupt the night growing cycle in greenhouses for growers that cultivate strawberries, cut flowers, bedding plants and cuttings. The new Philips GreenPower LED flowering lamp 2.0 builds on the first generation of Philips GreenPower LED flowering lamp and comes in two different spectral versions with light recipes for growing cut flowers and soft fruit. The new highly energy-efficient lamp is designed to increase the yield, quality and consistency of crops and accelerate flowering. Its design draws upon over twenty years’ experience that Philips Lighting has in horticultural lighting to serve the needs of growers.

The first generation of the Philips GreenPower flowering lamp provided an important benchmark for energy efficiency following trials in 2014 and 2015 at the Research Centre Hoogstraten in Belgium, an independent horticultural research center. The next generation lamp provides an optimum spectrum and high light output and allows growers to save electricity costs by being 90% more energy efficient than conventional incandescent lamps. The lamps have a standard E27 or E26 fitting allowing them to be used in existing installations, avoiding unnecessary modifications and reducing set-up costs.

Effective for crops
To help growers achieve the best results for their crops, Philips Lighting has invented light recipes which combine the following elements: light spectrum, intensity, uniformity, timing and positioning. The Philips GreenPower LED flowering lamp 2.0 is available with two different spectral versions: one offers a combination of deep red and white (DR/W) and the other a combination of deep red/white/ far red (DR/W/FR). The DR/W light version inhibits flowering of short-day plants, and has for example been very effective with chrysanthemums. The DR/W/FR light version is ideal for photoperiodic lighting of bedding and perennials. It can extend the day or interrupt the night cycle to promote elongation of the stems of strawberries and stimulate flowering.

“Being the first to market with a flowering lamp almost seven years ago, the Philips GreenPower LED flowering lamp 2.0 pushes the boundaries of how growers can gain control of crop quality and yield for their customers even more,” said Udo van Slooten, business leader for Philips Lighting’s Horticulture business.

Lower maintenance costs
The Phillips Green Power LED flowering lamp 2.0 looks like an incandescent lamp, but is made of robust plastic that mitigates the risk of damage to crops that can occur from broken glass lamps. To reduce maintenance costs, the lamp is designed to last at least 25,000 hours* and is rated for IP44 and UL damp and dry conditions indoors. Trials in countries which use photoperiodic lighting to produce cuttings or cut flowers have reported that the flowering lamp 2.0 is much more stable on the energy grid compared to incandescent or ”twisters” (CFLs), so there is less risk of quality issues in crop production. The two spectral versions of this new LED flowering lamp are available to provide full installation flexibility.

Heliospectra Promotes Sustainable Cultivation Methods and LED Light Strategies in Medical Cannabis Industry
Heliospectra, a world leader in intelligent lighting technology (https://www.heliospectra.com/) for controlled environments horticulture, forecasts that America’s growing public support of legalized medicinal and recreational cannabis use will push industry to more sustainable cultivation practices and cost-effective LED light strategies.

“An increase in the number of licensed greenhouses, indoor facilities and regulations will focus the industry on sustainable growing techniques and the documented data that integrated LED lighting systems and control technologies provide,” said Staffan Hillberg, CEO of Heliospectra. “Commercial cannabis cultivators recognize that the ability to dynamically adjust, monitor and customize the full light spectrum specific to plant need ensures consistent crop health, product quality and harvest results.”

Given the distinct possibility that November election results will expand licensed recreational states from four to nine in the burgeoning U.S. cannabis industry, financial and advisory firm Viridian Capital Advisors (http://www.viridianca.com/) predicts that attention will now shift to operating margins, long-term profitability and business efficiencies.

“As downward pricing pressure from the commoditization of cannabis continues, growers are rapidly adopting more advanced cultivation products and processes,” explains Scott Greiper, President of Viridian Capital Advisors. “Technology solutions, including LEDs, enable cultivators to establish competitive advantage and cost-effective operations while boosting yields.”

Heliospectra continues strong sales momentum of its programmable, full spectrum LED lighting solutions (https://www.heliospectra.com/led_grow_light_products) within the American and Canadian medical cannabis communities, bolstered by the unprecedented customer results achieved at The Grove Nevada (https://www.heliospectra.com/blog/grove-nevada-experiences-unprecedented-positive-results-their-grow-using-heliospectras-led-grow), Green Leaf (https://www.heliospectra.com/blog/heliospectra-closes-deal-alaskan-entrepreneur) in Alaska and other cultivation leaders who maximize revenue and return on investment with consistent harvests and quality crops while significantly reducing energy and HVAC costs.

All hail the all-knowing, no-showing Internet stoners and their calculators!
"Ah, is there room for both of us?

Both of us apart"
