DECREASE ELECTRICITY & REPLACEMENT COSTS: While LED technology is more expensive than existing fluorescents at face value, they will last longer, while consuming at least 50% less energy. In most general purpose lighting applications the additional cost of the LED technology will more than pay for itself in less than half of the lifetime of the LED tube light.

ELIMINATE HAZARDOUS MATERIALS, MERCURY EXPOSURE RISK AND RECYCLE REQUIREMENTS: LEDs are produced from non toxic materials. The tubes are made from polycarbonate, a material that is more robust and durable than glass, so accidents or replacements will not require special cleanup procedures. As has been popularly reported, fluorescent lights do contain a small amount of mercury. For those who wish to eliminate the use of mercury altogether, LED light bulbs are a better option. Should a fluorescent tube light break in your home, special handling techniques are required for clean up, as the mercury can escape from the bulb. This is not something to be concerned about with LED tube lights. LED lights typically contain no hazardous substances and are therefore environmentally safe to use. Our LED lights are both CE and RoHS compliant.

LOWER GREENHOUSE GAS EMISSIONS: An estimated 85% of the primary energy consumed in the US is generated from fossil-fuels. Solar-LED lights reduce the amount of energy used up to 90% and will ultimately help reduce your carbon footprint. The U.S. Department of Energy estimates rapid adoption of LED over the next 20 years can eliminate 258 million metric tons of carbon emissions. That is equal to removing 47 million cars off the roads or planting 43 billion trees.

LED technologies have come into our life in large scale applications such as LED Street and Parking Lot Lights. Although not directly similar to LED Tube Lighting, larger scale LED lighting applications are the foundation of known to savings in electricity and maintenance costs. Here is an article that explains how these savings were showcased at a recent Department of Energy research.

LED TESTING & APPLICATION; “THE COST FACTOR”, BY JAMES BRODRICK

“U.S. Department of Energy (DOE) has been doing research on LED lighting products and has a unique perspective, thanks in large part to its CALiPER and Gateway programs.

CALiPER Program conducts unbiased performance testing of off-the-shelf LED products.

Gateway Program showcases their use in real-life settings.

Outdoor area lighting

[For outdoor lighting], maintenance not only is costly, but also can be difficult. That’s why solid-state lighting is starting to pique the interest of retailers, facilities managers, municipalities and other stakeholders who look at the total cost over time rather than just the initial outlay.

For example, a recent Gateway demonstration at a California supermarket found the payback for bi-level LED parking lot lights to be less than five years, with energy savings close to 70 percent. The incumbent metal halide lights drew an average of 346 watts. In contrast, the LED lights (which reduced their output when no motion was detected around them) drew an average of 149 watts on high power and 52 watts on low power. Compared with metal halide, the LED lights cost $278 less per year to operate, when maintenance and replacement costs were also taken into consideration.”
