Energy Saving Street Lights
December 27, 2009 by Janet7
Energy saving Street Lights are now available in South Africa Environment Friendly Street Lights can light up your town and still ensure that we have a Green and sustainable Earth.
LED Lights can give more hours of light at a reduction in Electricity. If you compare the LED lights against the normal Mercury Vapour or High Pressure Sodium Lights you get energy and cost saving of up to 70 – 90 percent.
One key component about LED Lights are that they are Solar Power Compatible. It has Instant Start, UV and Corrosion resistance, minimal glare and other features. Many towns and municipalities can now start converting their street lights to the new LED Lights.
The new design street lights add a modern touch to cities and towns around South Africa. The lights also shine a brighter light which means you can replace a 250W Sodium bulb with a 70W LED light. The Led lights don’t need a Ballist and will save you the energy usage of the ballist as well.
These energy saving street lights are available in 30W, 50W and 70W options and can reduce a towns electricty bill dramatically. Not even to mention the dramatic effect that it has on the environment.
LED Street Lights also has a very long life span compared to the current lights. A normal High Pressure Sodium Light bulb needs to be replaced every 16000 hours while the LED technology is so rapidly moving forward that you only need to change it every 100 000 hours. This capital outlay alone saves the municipality or owners of the business enough to pay for the replacement.

Shift down and spin to take advantage of any momentum that you have going into the hill. The lower the gear the less energy you'll spend going up the hill. Get out of the saddle and let your body weight help you. Stay in a straight line. There are no points for taking the longest route up the hill. Don't waste energy weaving or rocking the only goal is the top of the hill. Keep pedaling over the crest of the hill you don't want to lose momentum that you have gained. Control your breathing by breathing in through your nose and out through your mouth. All of those things should help you climb more efficiently. The more you climb the easier it gets.
Thanks Quattron technology, I'm a fan! if you're in the market, get a Sharp Aquos LED!

Walking the walk is key when playing the environmental game, which is why we’re thrilled to report that the United States Department of Energy has completed their new zero-energy research building in Colorado. It clocks in at 222,000 square feet and is the largest zero-energy building in the United States. Boasting 50% less energy usage [...]
In the global picture, which is the worse evil? CO2 or Mercury?
I am actually a HUGE advocate of Solid-State Lighting (LED technology). There have been massive efforts to improve this technology, and the performance (color temperature and lumens per watt) has improved exponentially.
It is true that many governments (United States and Great Britain most generously) have provided funding to accelerate research, but that only goes so far…It pays to create the product, but what good is it if no one wants to buy it? Even though governments have dangled a carrot, that carrot has to be held over solid ground…Who would reach for if it if it were over a precipice?
The solid ground is people, bureaucracies and corporations like me. The biggest stable (probable) market is corporate. Yes, some is out of P.R. attempts to look “green,” but the majority is the same greed that is sometimes seen as evil. They want to cut their costs! Solid State Lighting is in some areas exceeding the lumens/watt of fluorescent bulbs. They surpassed incandescents nearly a decade ago. They also blow away all the competition in operational and replacement cost. Granted, a SSL bulb or fixture costs a lot more than the current alternatives, but they last (with extreme reliability) on the order of 10 years. I can't get a CFL to last 6 months. The reduced replacement frequency saves the company money by not needing a “light crew,” (my company has a full-time crew of six people for this for just my site, and at last count we have 50+ sites) and saves them money on electrical costs (my site pays more than $1M per year for power, my girlfriend's company (one site of nearly 100) pulls 6 Megawatts continually. Granted, lighting is a small, but noticable fraction of that.
If I can be motivated to pay more for the bulb (actually a LOT more, in the range of 20 to 100x the price) out of wanting to reducy my energy bill (NOT my “footprint”) and my dislike of replacing burned out bulbs, can't others be? YES! Will it be immediate? NO! Am I helping these bulbs enter the mainstream? Maybe insignificantly, but YES! Am I a conceited jerk, treating others who don't follow my lead like morons? NO! I find it's easier to catch flies with honey than vinegar…
Since my girlfriend's nephew is autistic, I've been exposed to the whole thimerosol debate. That is (was) a common preservative in vaccines, and is as heated as the global warming debate. Some people say the debate is over, others say the data is anecdotal at best. The key to the concern over thimerosol? Mercury. The fear of eating too much tuna? Mercury. The number two threat to sharks (after hunting)? Mercury.
The concern over Mercury is to the level that some parents aren't getting their children vaccinated. They consider Mercury to be a bigger risk to their childrens' safety than the diseases they help prevent. I'm not sold on how effective they actually are or are not, but since I don't have kids, I have time for the research to catch up.
A parent has the right to not vaccinate their children, which puts the entire surrounding community at risk by increasing the possibility of epidemics, potentially leading to drug-resistant strains of otherwise controlled diseases. The exponentially growing motivation for this decision? Mercury, not (theistic) religion. But in 2012, a parent won't have the right to buy a 100-watt incandescent bulb. Those who can't afford SSLs will have to buy a CFL. As a parent, you'd be drawn and quartered for having Lead paint, but you're a hero for having CFLs…wow!
…I digress…but it shows a heated peripheral discussion.
From what I remember of Mercury from high school chemistry, it's some REALLY nasty crap! Even the slightest use should be weighed EXTREMELY carefully. For that, I am thrilled to know that Mercury thermostats and thermometers are impossible to come by (possibly, probably illegal). We have researched the reproductive and brain function effects of Mercury for decades, and none of it looks good. Thanks to the decades of research, I think this debate can be categorized as over. I am unaware of anyone who is saying that it isn't nasty crap.
…Except for global-warming advocates…That's a strange perspective…I'm not saying that they are warm and fuzzy over it, but they are minimizing the concerns. They recommend recycling them, and handling them with gloves. Interestingly, only three of the 39 counties in Washington have the mechanism to recycle CFLs.
Are we maybe entering the same arena as timber thinning? In an effort to protect the animals (see Spotted Owl), timber companies were prohibited from clearing deadfall and sick trees. After some of the worst fire seasons in decades, some of the environmentalists are acknowledging that they missed something…In trying to protect the animals, they harmed them. The timber companies (in their evil, greedy approach to sustaining their business) were performing the same function as naturally-occuring forest fires. They were clearing out the flammables, which rejuvinates the forest. In the past, forest fires happened when and where needed to perform this clearing, but since adjacent land was also subject to the same fire effect (at different intervals), there were natural fire breaks. The natural clearing process kept the fires to a much smaller scale. This allowed proper “housekeeping,” while providing the animals refuges to escape to.
In the attempt to control one possibly damaging aspect, we have ramped up the use of another. Mercury was for a couple of decades nearly nonexistent in the American home (a good thing, I think). Now, it is in the preferred (thanks to environmentalist pressure) slot for home and commercial lighting. We are accepting one form of damage in lieu of another. If we have decades of data pointing to reproductive and brain damage, and a truly minimalized (if not dead) debate over its toxic nature, why have we accepted it over a gas (that surrounds and is CREATED BY us all), whose “tipping point” is still the source of heated debate?
Solid State Lighting is an alternative that is rapidly evolving to being feasible. Within a couple of years, I believe it'll catch on like a fire storm. Is delaying a couple of years really worth the possible effects of spreading mercury into every home in America? Is CO2 really so close to the edge to justify that? If so, we're screwed if Mt. Rainier (or any other volcano) erupts. Of course that is an exaggeration, but by how much?

I have to agree that this place is the greatest historical and cultural landmark in the Royal City. It is a wonderful stop for tourists to see. My only issue is that it is not lite up at night.
Many other communitys have churches that act as a centre piece of the town or city, and they light them up at night to showcase them.
I know in the past Church of Our Lady did light up the place but stopped due to the electrical expense of the light bulbs. With todays LED technology, it would cost so little and make this centre piece shine at night!
This is a tough one. I think the more general question is whether the goals we pursue at a societal-level must be reflected in our private lives. Leaving the issue of appearances aside (i.e. looking like a hypocrite), I am not sure that the individual action, on its own, is that important >> if I reduce my energy usage, does this reduce the pace of environmental decline, which reduces social concern about environmental decline, which means that everybody else is likely to use a bit more energy? If this is the case the net impact of my individual action is nothing. Of course, for an individual like Al Gore appearances ARE very important, even if his personal energy usage is trivial at a global level. Better for him to reduce his energy consumption simply to remove an easy way for critics to discredit him. N
