Maximize your LED energy savings

Get Smart with LED

LED is catching on, you can see shoebox pole lights and gas station canopy lights being converted to LED all through the Rio Grande Valley. They will be saving 40% to 70% replacing fixtures but with the right configuration there can be even more savings. Atomic vehicle parking facility. This facility is 100 acres and they previously only had 10 1,500 watt metal halides at the front of the facility. They knew they wanted LED and they decided on the LEXIN 300 and they now have 48 on 20' poles over the facility. I could not do a direct comparison with the 10 metal halides with the 48 LEXIN 300 they adopted but the metal halides took two and a half hours to warm up and 20 amps and then after they warmed up they dropped to 7 amps compared to the LEXIN 300 which pulled to amps and light up to 100% instantly.

 Then Stephen Whitman facilities manager at Royal Freight began with a goal to replace the three outdated and heavily degraded 1,000 watt metal halide fixtures at their Pharr, Texas facility, the metal halide fixtures kept burning out and they were heavy and were not suited for the wind pressure variables. These fixtures were blown off in a wind storm. The metal halide replacements would have to be three Pulse Start Shoebox fixtures pulling 775 watts and costing $680.00 distributor net. He had a 25' pole in the center of the lot and he placed an order for a LEXIN 300 with a diffuser dome and pole mount for a downward direction of the fixture. Stephen said "I like the color of the light and it save a lot of energy, 300 watts is a lot less than 3,000 watts.”  The configuration of this fixture is the LEXIN 300 with standard lumen output of 31,990 lumens with a polycarbonate diffuser dome reduces the lumens to 27,000 but in turn it broadens the beam angle to 200 degrees with a 360 degree spread. The optimum height is 35'. The fixture is mounted with a pole top Garden Fit Mounting Bracket. It comes with a rear mounted driver housing or for easier access the driver can be remotely connected at the bottom of the pole.

Whenever I see car dealerships and shopping center parking lots with three or four shoebox fixtures on a pole I picture LEXIN 300 with this configuration. Rather than replacing fixtures head to head. They will still save energy but when you apply certain strategies you can save even more on instillation but also with you electric bill. If you can save just by switching to LED and then compound that savings by optimizing the position of you lighting using one fixture to replace three or four existing fixtures, how much would you have to save to make it viable? If one to one saves 40% to 70%, then compounding that by replacing three or four fixtures with one fixture at the optimal height and angle you savings can go from 80% to 97%. That is not including the maintenance. Do the math, look at how many canopy lights and shoebox lights you are using, divide that number by two for the energy savings just from switching to LED, then divide that by 60% and then subtract the maintenance of replacing the metal halides and high pressure sodium fixtures every four to 12 months? You tell me if it makes sense?
