Cree Introduces Brightest Horticulture LEDs

New photo red LEDs said to deliver more than double the flux density of nearest competitor

Cree has announced the XLamp XQ-E and XP-E High Efficiency (HE) photo red LEDs for horticulture, delivering up to 21 percent higher output than the previous generations of XQ-E and XP-E Photo Red LEDs.  

The XQ-E LEDs are said to set a new performance benchmark by delivering Photosynthetic Photon Flux (PPF) levels up to 5.39 µmol/sec at 85degC from a package footprint of 1.6 x 1.6 mm. The ratio of output to size is claimed to be 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 85degC and is the first LED to break the 1W radiant flux barrier at this temperature, according to Cree.

"The XQ-E family provides a unique combination of ultra-compact package, high output and wide range of horticulture-optimised colours," 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 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 optimised for horticulture, including white, royal blue and far red colour options."



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
