When you are purchasing lighting these days and you choose LED, the reasons might be energy savings, longer life, environmental, or even because that is what is on the shelf. It’s definitely caused a revolution; however, many are just starting to see the many benefits beyond the most obvious. The below article and interview summary have some good additional reasons ….
We are in the midst of a lighting revolution.
The past decade has seen LED light usage soar in the U.S. as traditional incandescent bulbs went into the trash bin.
In 2010, incandescents were 68% of the bulbs installed in U.S. homes. By 2016, that number had declined to 6%.
That change has shaken up the industry in a good way. Mark Rea, professor at the Lighting Research Center at Rensselaer Polytechnic Institute, tells Here & Now’s Jeremy Hobson that the benefits of LED lights “really make it kind of a slam dunk for a transformation in the way light sources are sold.”
He says those benefits include how many lumens per watt LED lights provide, long-lasting capabilities, ease of control, their glow and the ability to have multiple color options.
On the benefits of LED lights
“I think there are two touted benefits. One is how many lumens per watt you get out of it. So an incandescent lamp might be 12 to 15 lumens per watt, and depending on the LED you might get 100 lumens per watt. So that’s a big jump. And the other is longer life. That depends on the application, but generally speaking incandescent lamp might last, say, six months in your home. These can last up to 10 years. So those are really big differences but there are other benefits that people don’t talk so much about. They’re easy to control. So you can do some fancy stuff with them whether you put them on a bridge or you want to have a disco. There’s no filtering that you have to do. It will directly emit the wavelengths you want so you can have a red one or a blue one or a white one.”
On LED lights’ effects on the lighting industry
“People hate change. That’s the first thing. I don’t think anybody anticipated what a disruptive technology [this] was really going to be. For 100 years, we’ve had just a handful of major manufacturers and they pretty well set the standards [and] the policy. And the reason was it was very expensive to try to be in that business. It took a huge capital expense that no one wanted to commit to, to say produce fluorescent lamps or incandescent lamps. With LEDs, they’re cheap and anybody can be a lighting manufacturer now. So it’s really brought down … these major players that really set the tone for ….read more at https://www.wbur.org/npr/746293491/led-lights
Were you squinting to see what was happening during Game of Thrones‘ Battle of Winterfell? The episode’s cinematographer says you might just need to adjust your TV set.
Many fans complained that certain scenes in Sunday’s climactic episode of Throneswere too dark to make out, but the director of photography Fabian Wagner, who shot “The Long Night,” lays the blame instead on fans’ TV settings. “A lot of the problem is that a lot of people don’t know how to tune their TVs properly,” Wagner told Wired UK. “A lot of people also, unfortunately, watch it on small iPads, which in no way can do justice to a show like that anyway.”
Even the room a viewer watches it can have an impact on the visuals, Wagner adds: “Game of Thrones is a cinematic show, and therefore you have to watch it like you’re at a cinema: in a darkened room… if you watch a night scene in a brightly lit room, then that won’t help you see the image properly.”
Comments from RG: if you like me, were one of the 17 plus million viewers, of Episode 3 last week, it did not disappoint. Good explanation on the lighting ….Maybe a little dim sometimes but suspenseful every second. Can’t wait until tonight.

It’s not possible for the world to just “fuel switch our way out of global climate disruption” according to one construction industry observer. We have to invest significantly in making buildings energy efficient at a rate much greater than we do now.
But as anyone in this game knows, the financial returns on investing in eco-retrofitting buildings are hard to capture. That isn’t stopping people from trying, with Great Britain, the USA, and Canada taking very different route
Utilities are financing retrofits in the USA
As might be expected, in the USA it’s left to the private sector utilities to find ways of funding energy retrofits. You might wonder why they would want to, but it’s often cheaper for them to do this than invest in new generation plant.
Non-profit affordable housing providers who are members of Stewards for Affordable Housing for the Future received an average of $750/unit (AU$1057) in utility incentives and consequent annual utility bill savings exceeding $125/unit (AU$176) at participating properties. But there remains an estimated $16 billion (AU$22.55 billion) savings potential in the sector.
That’s partly because of the many barriers that exist. Occupants of these houses have limited time or capability to participate in these programs and while industry players have done their best to make it as easy as possible, there is a way to go.
These energy efficiency upgrades fall into three main categories:
whole building retrofits
direct installation of efficient appliances, and
prescriptive and custom incentives, or product rebates.
In Pennsylvania, the PECO Smart Multifamily Solutions Program offers building owners direct installation measures for lighting and water efficiency measures in common areas and units, at the same time assessing properties for potential energy savings.
Prescriptive programs offer financial contributions for standard energy efficiency projects like HVAC or lighting upgrades.
Others offer custom financial incentives for more complex projects. Examples of these are the Consumers Energy Multifamily Program in Michigan and the ComEd Low-Income Multifamily Program in Illinois, where owners can improve their HVAC systems and install efficient light bulbs or appliances or apply for incentives to save money on other upgrades.
These programs have shown that several barriers can be overcome if tackled the right way
These ways are:
Free or highly subsidised measures address one of the biggest barriers to efficiency in rental properties — the split incentive.
Whole-building incentives based on energy savings thresholds encourage deeper retrofits and help owners make more cost-effective investments and benefit from greater bill savings.
One-stop-shops or technical assistance overcome the problem of residents’ low capacity to manage retrofits by offering a single point of contact for everything.
Programs targeting multifamily-specific issues such as common areas and measures or metering make it much easier to get people on board.
Comments by RG: Interesting read about how energy upgrades are financed in different areas. Here in the USA the Utilities play a major role. Contact me here on my site for help and to discuss the help available to you.

Helping property owners refurbish and upgrade the energy efficiency of their buildings would save money, generate jobs and reduce carbon pollution.
The Washington Legislature can act now to improve the environment, grow good-paying jobs and save money. Those triple bottom-line benefits are all possible if the Clean Buildings for Washington Act (Second Substitute HB 1257) becomes law. That’s why our organizations — the NW Energy Coalition, the Northwest Energy Efficiency Council and the BlueGreen Alliance — enthusiastically support this effort.
In Washington, our buildings account for 27 percent of greenhouse-gas emissions. They are our fastest growing and second largest source of emissions — up 50 percent since 1990 — and commercial buildings make up approximately half of these emissions. Unlike cars, buildings last a long time and, without investment to address their energy use, they will continue to waste money and create unnecessary climate pollution.
Large, poorly insulated commercial buildings that rely on antiquated lighting and heating systems use inordinate amounts of electricity and natural gas. By making these buildings more efficient and reducing the amount of energy they consume, we can slash associated pollution and emissions and also reduce the likelihood that we’ll ever have to build another fossil fuel power plant again.
This legislation would take decisive action by renewing and investing in large, older commercial buildings of greater than 50,000 square feet. This is a small portion — about 6 percent — of the commercial buildings in Washington, but they make an outsized contribution to our emissions.
Comments by RG: Favorable Acts, Legislation, and Rebates all can really help to improve lighting and energy projects. This pending Washington Act would be great for Property owners in that area. Contact me here on site for what is available in your area.
