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.
Are you confusing these with those crappy fluorescent junk bulbs? If so, I agree. But so far, I really like the light and power consumption of LED's. Most of the ones I have been buying have been rated for 22 years. Can't gauge that success so far, but I do have a few earlier ones that have stayed on 5 years with no problems. Still hoping the prices keep going down though.
Will they have time to increase the number of bulbs by threefold, in order to get the same amount of light?
My experience will certainly change at some point as I install more and more throughout my home and workshop. I'm buying 40W Utilitech LED's at Lowes now for $4.00. 60W are around $7 I think.
“you can’t dispose of them in the trash and you create a hazmat zone if you break one.”
They are easy to dispose of. Just take them to where they came from, like Home Depot. Drop them in a basket in the lot or put them in the restroom trash can. Problem solved!
The first super bowl lit with energy-efficient LED lights. Wow, this is one for the history books. Why not take it a step further? The first super bowl lit with energy-efficient LED lights that were installed by an all-black maintenance crew!
If they were serious about “saving energy”, they would play the game in an outdoor stadium with a 1p.m. kickoff.
You will note, however, that your oil or gas burner uses more oil. Incandescent lighting has an added benefit of 100% efficient resistive heating.
Huh?
"The light measured on the field nearly doubled to 277 foot candles."
"Ephesus fixtures continue to maintain 90% of their original output after 10-years with no maintenance as compared to metal halide bulbs degrade by 40% in 18-months."
I doubt it. I see AC power LED fixtures as the appropriate solution. Easy to change to any type of future fixture as needs or technology changes, rather than dedicated wiring tied to one technology.
Light level on the field is about double from prior levels with 10 tons less in fixtures.
The other thing that gets me... the wavelength they have developed for the "blue" strobes for modern LED equipped lightbars on cop cars... I think it was intentionally made to disorientate people on a roadside sobriety test. To me, those things are like "Puke Lights". Pretty sure that was the intent.
Ephesus’ patented technology uses extremely-high-frequency pulse-width modulation (PWM) to allow HDTV recording of up to 1,000 frames per second for reduced glare, superior slow motion and flicker-free recording. The Ephesus custom-designed circuitry adjusts the CCT and CRI to quantify the light source for optimizing HD camera telecasting. Pulsing at a much higher frequency than any frame rate used today ensures the highest quality of light for HDTV recording to guarantee an excellent television viewing experience.

I am a strong believer in LED for my industrial applications.
Our total installed cost is more than double the material cost of the fixtures. The total cost of the installed light more than justifies using LEDs for our lighting system with lower power which means less wire, panelboards, transformers etc, not to mention the cost savings with energy and maintenance costs.
But project after project, we get managers fixated on the initial fixture cost and will not make smart project decisions.
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!
The LEDs of today are so far removed from those of 3 years ago that any comparison is silly. I could not even guess how may exterior LED wall packs, floods and high masts we have replaced in the last two years but I can tell you that the results are universally applauded. More light, with better color rendition, less than half the wattage, lifetimes in the 100K range and very low failure rates.
We are just finishing up an installation of LED high bays in a rather large building - over 2,000 fixtures with individual daylight dimming and occupancy controls. We replaced 250W sodium units with 166W LED and increased light levels 15 - 20%.
Home LEDs are usually offshore manufacture and more prone to failure but they are catching up quick. The recessed lights in my office are LED, have been in for 2 years and no on e can tell that they're not fluorescent until I take off the lens and show them. And they are fully dimmable and are connected to a building automation system too, all with CAT5 cables.
LED is the best option, especially for anyplace where maintenance is an issue or electricity is expensive.
And there would be FReepers who would bitch about how transistors suck in comparison to their grand-pappy’s tubes.
