That would make a nice grow light combo!

Can't seem to find a base for them yet but the future is bright. Too bad there are no 3070 90 degree options yet..that sounds just about right..

After 6000 Hour LM-80 Test Completion - Luminus Gives 5 Year Warranty on XNOVA Chip-On-Board Array LEDs
Luminus, Inc., a global manufacturer of highperformance LEDs and solid-state light sources, announced today a five year limited warranty for the XNOVA family of chip-on-board (COB) arrays designed for both indoor and outdoor directional lighting applications. The company introduces this warranty on the heels of competing their 6000 hour LM-80 testing which demonstrated long term color stability and robust lumen maintenance, even under extreme conditions including both high temperature and high drive current.
Luminus Devices' XNOVA COB LEDs which are available as High-CRI versions and narrow 2-step binning now are backed with a 5 year warranty
“Our XNOVA COB arrays have already been recognized by customers as having industry-leading efficacy, value, and quality of light, and now we have long term data and the 5 year warranty to give customers peace of mind knowing that their fixtures and bulbs will comply with Energy Star and deliver consistent performance for many years to come,” said Jim Miller, Executive Vice President of Sales and Marketing for Luminus. “Our mission is to help our customers achieve new levels of performance in their end products, so that they can gain advantages over their competitors, and this 5 year warranty helps our customers confidently position themselves as providers of robust, long lasting bulbs and luminaires.”

Luminus Devices will be showing their XNOVA illumination product line at the Hong Kong International Lighting Fair, October 27-30, 2014. For more information on the XNOVA product line, please visit: www.luminus.com/products/xnova.html

Osram Announces New Soleriq S 19 Versions with Two Different CRIs
Osram Opto Semiconductors launches new product versions of the Soleriq S 19 with two different color rendering indexes (CRI). As with all versions of the S 19 the new LEDs can be used in all applications where high lumen packages from a compact light source are needed. They are especially suited for professional downlight and spotlight applications, for example in shop and office environments.
Osram's updated Soleriq S 19 LEDs offer CRI 80 or 90 and between 2,000 lm an 5,000 lm
Technical Information:
Package Size: 24 mm x 24 mm x 1.4 mm
Brightness and Efficacy (at 4000 K and 85°C):
CRI 80: 2800 lm, 117 lm/W; 5361 lm, 116 lm/W | CRI 90: 2420 lm, 101 lm/W; 3400 lm, 104 lm/W; 4610 lm, 100 lm/W
Light-Emitting Surface (diameter): 19 mm
Color Temperature: 2700 to 4000 K

The new Osram Soleriq S 19 LEDs are available with color rendering indexes (CRI) 80 and 90. There are two CRI 80 versions with brightness values of 2000 and 5000 lumens (lm) and three CRI 90 LEDs with 2000, 3000 and 5000 lm. An S 19 LED with CRI 80 and 3000 lm has already been launched. As with all Soleriq S 19 LEDs the new products are based on the standards defined by Zhaga and have a light-emitting surface with a diameter of 19 mm.

With the new product versions Osram Opto Semiconductors now offers one LED family (Soleriq) with similar package size and various lumen and CRI options, so customers neither have to change optic and reflector design nor connectors when upgrading their product range. Furthermore, the LEDs can be driven in low-current mode to achieve even higher efficacies or in high-current mode to achieve high light output. In this way, different requirements of luminaires can be met with the same set of optics and holders.

When installed in lamps and luminaires, the new Soleriq S 19 LEDs can be used for professional downlight applications in offices and shops but also for hospitality lighting. They offer a high flexibility in this context: If customers want to implement lighting solutions in rooms with lower ceilings, e. g. offices, they can choose the S 19 version with 2000 lm. If rooms with high ceilings are to be illuminated (e. g. shopping malls), an LED with a high lumen package is the perfect choice.

All Soleriq LEDs are based on Chip-on-Board technology. This technology guarantees a uniform color and light appearance thanks to the close arrangement of the chips beneath a conversion layer. The LEDs are very simple to work with as they are screwed to the heat sink with a connector. Then the connecting wires just need to be inserted into the connectors provided and fixed in place. There is no longer any need for SMT (Surface Mount Technology) soldering. Accessories such as connectors, optics and drivers tailored to the Soleriq family can be obtained by the Osram partner network LED Light for you (LLFY). Customers can either go to the LLFY website or use the free “LLFY Selector” app so they can find the perfect products on the move.

Additional information can be found on the Osram-OS website.

About Osram:
Osram of Munich, Germany is one of the two leading light manufacturers in the world. The company's portfolio covers the entire value chain from components – including lamps, opto semiconductors like light-emitting diodes (LED) – to electronic control gears as well as complete luminaires, light management systems and lighting solutions. OSRAM has around 39,000 employees worldwide and generated revenue of 5.4 billion Euros in fiscal year 2012 (ended September 30, 2012). More than 70 percent of its revenue comes from energy-efficient products. The company's business activities have been focusing on light – and hence on quality of life – for over 100 years.

Thermal Interface Materials (TIM )

Thermal Material Composition
Thermal Interface Materials (also known as thermal compound, grease, and paste) use one or more of the following thermally-conductive substances in their formula:

Carbon-based Thermal Interface Materials
  • Carbon-based TIM's have recently become extremely popular for manufacturers over the past two years. Carbon nano-tubes, carbon fibers, diamond powder, and other exotic mixtures are now being used in many commercial products. Because this method of building a thermal material has become the current market standard, most recipes are considered an industry trade secret. Carbon-based TIM is generally non-conductive and will not transmit electrical energy, making it perfect for all electronics application. As of May 2009, Carbon is the most widely used component in high-performance premium thermal paste products.
Metal-based Thermal Interface Materials
  • Past generations of popular thermal material products have been metal-based, using a component that includes solid metal parts in the formula. The most popular ingredients feature silver, copper, or aluminum as their base. Metal has a better thermal conductivity than ceramic-based material. Unfortunately metal is also electrically conductive, which can cause problems if it bridges the contacts or electrical connections on an integrated circuit. Metal-based TIM's are not as prevailant as they once were, as the cost of manufacturering often exceeds the benefit over using other compounds.
Ceramic-based Thermal Interface Materials
  • Ceramic-based thermal material offers a decent thermal conductivity performance, and remains the most common component used in generic and low-cost thermal pastes. Ceramic-based material and is usually composed of a ceramic powder suspended in a liquid or gelatinous silicone compound. This material is often given the name "silicone paste" or "silicone thermal compound". The most commonly used ceramics and their thermal conductivities (in units of W/m·K) are:beryllium oxide, aluminum nitride, aluminum oxide, zinc oxide, and silicon dioxide. This Thermal Interface Material is usually white in color, since these ceramics are all white in their powder form, and has earned the name "white paste" inside enthusiast circles.
Liquid Metal-based Thermal Interface Materials
  • Some Thermal Interface Materials are made of liquid metal alloys or gallium. These TIM products are rare, and often times corrode metals they are not meant to come in contact with.
