As a result of the reduced fixture count, over 20,000 pounds of weight was taken out of the catwalks.
The light measured on the field nearly doubled to 277 foot candles.
Ephesus fixtures continue to maintain 90% of their original out after 10-years with no maintenance as compared to metal halide bulbs degrade by 40% in 18-months.
All Ephesus Lighting fixtures are manufactured and assembled in the U.S.A.

Can’t wait to see all the missed catches. I bet they had to get bulbs with double the amount of lumens than what they would normally need on a standard bulb. Sorry but these new “energy-efficient” bulbs just aren’t as bright and the go out a lot faster. I’m beginning to think the light bulb manufacturers were behind pushing for this crap because they are gonna make a lot more money with bulbs costing more ad not lasting half as long...
Well, that oughta lower the ticket prices. /s
We relamped our church with LED’s and noticed the same thing. About an 80% reduction in power consumption. Well worth it once you get over the shock of the initial cost.
I know the photographers are excited about having good light to work with.
Cool! (pun intended) I like LEDs. I’ve got 8 or 10 LED flashlights ranging from cheap to moderately expensive (as tactical lights go). They’re bright, virtually indestructible, and don’t use much battery. I’ve only ever had one LED light fail a Fenix TK-10 which is a cheap Chinese light (in the realm of tactical lights). That was a regulator circuit that died. I’ve got a Coleman and a couple of MagLites that are just great. The Mag XL50 in particular is a great little light. I keep one on the nightstand.
CFL bulbs were a crappy hoax foisted on us by our masters in Washington DC. They fail quite frequently, don’t save as much energy as an LED, you can’t dispose of them in the trash and you create a hazmat zone if you break one.
LED bulbs have evolved through capitalist innovation. LED bulbs actually save a ton of energy, are becoming quite affordable and I have never seen one fail. I have a few security/night lights that have been on for 5 years.
As usual, free market wins.
Any chance that future houseing might have a DC circuit to ceiling fixture and some outlets to accommodate this LED bulbs?
Another benefit, depending on how they’ve got these fixtures wired, is that you can set them so a few of the LEDs in each light unit are also connected to a battery backup system. If power is lost, the batteries can keep a few of the elements in each fixture lit for a considerable amount of time due to the low current draw, maintaining at least some illumination on the field and stadium for safety. IOW LED fixtures can have built-in “mercy” lights.
If they were serious about “saving energy”, they would play the game in an outdoor stadium with a 1p.m. kickoff.
Bellichick was caught switching out the light bulbs.
Imagine that... CAPITALISM (the pursuit of more profit though cost savings) solved another problem.
and without a government order!
An entire article that provides the economic benefits and quality improvements of lighting with LED, without a hint of “global warming” as a reason.
Very refreshing.
In addition, the LED lights turn on without the 15-20 minute warmup period required by metal halide and other HID lamps.
...
That and the savings in cooling costs are the real benefits. The cost for electricity with the old lights was minimal.
I’ve learned about LEDs the hard way. My experience.
60w LED appears brighter than a comparable incandescent to me.
Kelvin rating is something to consider when buying LEDs.
2700K is about the color of an incandescent, higher K temperature gets whiter.
Many cheap LEDs are 3000K or higher, ugly, harsh IMO.
Some LEDs, Feit Brand bulbs sold by Costco can cause RF. It states so on the back of the pkg in little tiny print. I called the Co., BTW
Don’t use them near a radio. I took them back.
Home Depot sells Cree bulbs, Made right here in Morrisville, NC.
60W equiv. about $5.
But designer bulbs? Too much $$. I’ll wait on the candelabras, globe prices to come down before I replace them.
And last. I’m stuck with a bunch of nasty CFLs. :^(
Shoot, they could have made that up by selling an extra three hot dogs.
doesnt matter what kind of bulb if the power goes out like it did in the superdome 2 years ago.
Very cool.
I’m concerned that this lighting change will affect the air pressure in the footballs being used. /s
>>The new lights draw approximately 310 kilowatts of energy compared with the 1,240 kilowatts required by the old system, a savings of about 75%.
That difference represents a savings of about 265 tons of air conditioning, assuming they need to run mechanical refrigeration vs. just ventilation with cool outside air. Which is probably the case for any number of games in AZ. Your home unit is typically about 3 tons, for comparison.
The energy savings in not having to run that much air conditioning is probably around 1/3 of the direct lighting kW savings, so around another 310 kW saved on top of the 930 in lighting operation saved.
