Macy's Replaces Halogen with Super Efficient, Cool Burning, Green LED Bulbs, Saving Millions

Total energy savings are estimated at about 16,200 megawatts per hour every year, the equivalent of planting more than 65,500 trees.

MSi Solid State Lighting announced in 2010 that they helped Macy's to go green lighting. They helped Macy's make major strides in its ongoing drive to reduce energy consumption and waste as part of the company's comprehensive program of sustainability and operating efficiency.


One of these steps is partnering with LED lamp manufacturers, including MSi Solid State Lighting, to be the first department store company to implement the use of LED accent lighting on a wide scale.

The company replaced about 117,000 traditional incandescent light bulbs in 86 Macy's stores with new LED bulbs that use about 73 percent less energy.

Total energy savings are estimated at about 16,200 megawatts per hour every year, the equivalent of planting more than 65,500 trees.

The LED lamps have an expected life of 10 years (compared with less than one year for traditional bulbs), reducing landfill disposal.

The conversion to LED was a simple matter of unscrewing the old lights and screwing in the new ones, but the results were immediate and dramatic. Unlike hot burning halogen lights, the extremely efficient LED lights produce very little heat and within hours of installation, store employees had noticed a drop in the store's temperature. "Many retailers are a little concerned about the initial investment of converting to LED lighting," said Bruce Johnson, MSi managing partner, "But if they take the time to run the numbers as Macy's has, they'll see that switching over produces a tremendous return on their investment."

LED lighting produces savings that go far beyond just cooling cost. LED's use a fraction of the power required by halogen spots while producing a clean, clear light that enhances product displays and merchandise.

Additional savings are realized in the lower maintenance and replacement cost for LED lighting. The typical 60-watt halogen light burning 12 hours a day will need to be replaced approximately every six months. The new Macy's LED lamps burning 12 hours a day will last for more than a decade.

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
