GNP (Great Northern Processing) began as a dream back in 1990 and by 1993 we had developed the first full scale commercial production facility in the World converting waste Oil to a high grade usable Diesel Fuel (green technology). Our first plant was built in Huntington, Indiana USA. we have since licensed operational plants in Belgium and Malaysia. We formed a strategic partnership with Aldwich, one of the world’s leading design and build Waste oil producers in the World with exclusive licensing and marketing rights to the GNP process.
In 2009 the lighting division was born GNP Energy LED (Green Technology) GNP Energy is on the cutting edge of LED lighting conversions for commercial, Industrial, and municipal infrastructure. We have partnered to market our Patented line of high quality USA Manufactured LED lighting systems which save customers 70-90% on electric and last upwards of 20 years! GNP has to date completed numerous full city street light retrofits along with countless municipal and commercial projects.We will continue to be on the cutting edge of high quality green technology which saves money and improves quality of life as we have now for over 25 years.
Many of our clients benefit from a little hand holding when considering embracing this new technology shift. There a lot of numbers thrown around that are difficult to put into context… sort of like HDTV a few years ago… We decided to address the primary concerns from the very start, with our patent-pending thermal management design and our industry best 10 year warranty. GNP (Great Northern Processing) has been in business for over 20 years, and we now license our core energy technologies in several countries. Our lighting products are manufactured here in the US, providing our clients access to the Buy American Recovery Reinvestment Act (ARRA) funds to substantially assist in reducing the initial investment.
Manufacturers of high–brightness LED lamps and fixtures make wild claims as to product life. How can you determine if the product you are buying will last the 15-30 year claims?
LED life is measured in lumen depreciation. This is the percentage of light output degradation from the initial light output. The industry standard is determined by the Illumination Engineering Society of North America. Look for LM-80 specifics for determining lumen depreciation. When researching the different LED vendors and their datasheets, look for proper heat sink and thermal management of silicon junction temperature to discover the lifetime of the LED. Look for lifetime versus junction temperature graphs in LED vendor datasheets that show lumen depreciation. If they do not provide these data sheets and charts, or if they do and the temperatures are 80C, stay away.
For example, a LED chip operating at 40C will last 150,000 hours, while the same chip operating at 80C will only last 50,000 hours. It is typically impossible to get the LED’s to operate at 40c or lower without some secondary cooling system, such as a fan. Our LED system uses a primary heat sink with a secondary MagLev™ fan. This is the most effective way to remove the heat from the LED system. Ask the manufacturer what the heat rating of the product is before purchasing.
The LED power supply or driver design is the other factor that determines lifetime. Find out how the current is being delivered to the LED. Most companies use either a constant voltage or constant current driver.
The driver being used can give you insight to how well they understand LED lighting. A company that designs a LED lighting system using constant current driver incorporates a daisy chain system where LED’s are lined up in series. This type of design typically causes the forward voltage and current to vary greatly from the first LED down the line to the last.
Ask your LED lighting supplier how they protect their lighting array. When spending a lot of money to get a system designed to last 20 plus years, this is a good question to ask. Make sure they have under voltage protection, over voltage protection, and overheating protection. These systems insure your LED lighting system will not be compromised. All LED systems are not created alike which is why our lights last up to 80% longer than other LED systems.
Over time the first LED in the chain will get higher voltage and current causing it to operate hotter and thereby causing color shifting and premature failure. We also incorporate surge protection strategies to protect your technology investment, you wouldn’t hook up your new computer without proper surge protection.
Look for companies that incorporate constant voltage drivers in their systems, they typically have a greater understanding of LED technology. Our LED products use constant voltage drivers to deliver the voltage to the PCB where the LED chips are mounted. From the board, the voltage and current are distributed to each LED to guarantee exact current and voltage is provided with little fluctuation.
