Everything about the Olympics is a big deal. This isn’t just true about the competitors but also for the behind the scenes works such as commercial lighting.
For the last four days I’ve done nothing but watch the Olympics. Day and night, the Olympics have dominated the television in my house. Get together’s have been canceled, dinners have been rearranged and my DVR has been cleaned out for the events that I miss. There is just something about the pageantry of it, and, more impressively for me, the entire massiveness of it. Just the commercial lighting that has to be utilized to light over a dozen venues for the fans is amazing. I know, I know, here are Olympic athletes giving there all for the chance at gold and I’m focusing on something as small as the “lighting”, but if you think about it its small stuff like this that has to be meticulously considered to put these games on.
Imagine that it’s your job to figure out how to light a venue at the Olympics. Sounds easy enough, but for anyone who has had to work on commercial lighting before (and I have, maybe that’s where this interest comes from) knows that there is a lot to consider when lighting something as important as an Olympic venue. Take, for example, the Richmond Olympic Oval, home of the Speed Skating events for the games. Whenever you’re dealing with ice you have to be careful with the lights you use. If it’s too bright or put at the wrong angle you could be dealing with massive glare off the ice. The trick is, though, you have to be able to light the venue for television while being considerate of the skaters. How do you do this? I don’t really know, I guess that’s why they are professionals and I’m just a blogger.
The Opening Ceremonies of the games was one of the most amazing lighting jobs I’ve ever seen. The director of the ceremonies (who has previously directed the Opening Ceremonies for the Sydney games in 2000) used over 70 projectors to create stunning visual moments that helped bring people an up-close look at Canadian Culture. One of the most striking moments were a pod of projected orca whales moving across the stadium floor. In all, by using the projection lighting, the director was able to make a lot out of a little. Very rarely were live props used, but instead by using the lighting projected onto white objects it looked as it the arena was covered in water or leaves or snow. It was definitely a sight to behold.

It takes several key components to set up a successful salt-water aquarium to garner success. Correct PH levels, the right high bay lights and the right coral reef set up are all key components you’ll need to research to ensure a copasetic environment for your marine life.
The most important set up tip you can get is to gain as much information as you can concerning the proper PH levels for marine salt-water aquariums. No matter how pretty your set up is, if your water levels are out of control your marine life will not be alive for long. In general the larger the tank the less likely you are to have spikes in PH levels. The minimum suggested size for a marine tank is 30 gallons and preferably higher. Anything less than 30 gallons and you’ll spend as much time checking water quality as you do watching your fish. Maintaining proper salt levels will help to ensure you maintain a healthy environment for your under water world.
Lighting is also a major key in maintaining a healthy living environment for your marine life. Most people who want a well-balanced salt-water tank want some level of a coral reef. This is needed to sustain that balance. If you don’t want a reef then lighting is not as essential but if you do, then going with high bay lights as the systems will help you maintain the correct levels of UV for your aquarium. You can buy commercial hoods complete with lower quality ballasts and brackets or you can buy lighting systems designed to light! Most experienced reef owners will tell you that sit on top hoods pale in comparison to open tanks with high bay lighting that is suspended above the tank. It causes less heating issues and also acts more like the sun (in the fact that it’s farther above the water, not right on top of it.) Most suppliers can also help you with setting up daytime lighting and nighttime lighting. It’s been proven that marine life get just as much benefit from moonlight as they do sunlight. For some reefs, moonlight is even more important than sunlight.
Once you have your reef, lighting and PH in place you’ll need to focus on filtering. Freshwater aquariums require much less filtration than well balanced marine set ups need. Bacteria tanks are often employed to ensure the fish are getting the right amounts of bacteria. Skimmer filters and salt filters are also commonly used to ensure the conditions in the water are properly balanced. This is one of the largest costs of owning a salt-water set up and will also be one of the most labor-intensive projects for your tank. However as tedious as it may seem, proper filtration of the water is key to success.
Maintaining a marine tank will always be more labor intensive then a fresh water tank but you’ll rarely see anything in fresh water nature that compares to the majestic flow of marine life and coral reefs. The benefits out weigh the work involved in maintaining a reef tank.

Most homeowners are worried about the security of their homes and the family and possessions they house in them. A flood light can be an essential security tool to minimize your risk and ensure your house doesn’t get broken into.It’s a well accepted fact that most robberies and crimes tend to happen during the night. Criminals quite like operating under the veil of darkness as they are easier to detect and therefore foil. A homeowner should always keep this in mind and try to ensure that gardens and house fronts are well lit. Street lighting can suffice in most circumstances, but for areas that don’t have enough light, one should consider purchasing and installing a flood light.
Different varieties of flood light exist, but the ones commonly used on domestic premises tend to be 250 or 500 watt tungsten. It’s common for a flood light to include a passive infrared (PIR) motion sensor) for the light to come on when movement is detected. Flood lights should be mounted to make sure that they shed light into areas where a robber may hide and remain undetected in normal circumstance. It is important to pay heed and attention to where a spot light may be mounted. For example, the light should never shine into neighboring homes or onto neighboring property and this may be perceived as breaching their privacy. Also, a flood light should always be pointing downwards as this max most use of the light it generates. The ideal angle for a flood light is an angle of 22 degrees. In this position it illuminates walls without blinding an observer who may not be able to witness the intrusion otherwise.
There are a few things you need to keep in mind when using a flood light. If used incorrectly they will not provide any security, but instead pose a risk to your property and your visitors. Here are some things to keep in mind:
1. Make sure the flood light is not in a position where it can distract drivers. They can be a source of accidents by temporarily blinding someone in charge of a car. 2. If a floodlight is incorrectly installed it can actually help a robber by blinding onlookers or providing shadows for criminals to hide in. 3. PIR sensors can be triggered by cats, dogs or things moving in the wind. This can cause false alarms and desensitize your neighbors to the flood light coming on. 4. A 500W flood light can be quite expensive to run (and has a large impact on the environment). Sometimes, just an ordinary 60W light bulb is enough for your needs.
Keep these points in mind when purchasing and installing a flood light as the only thing worse than no security is a false sense of security.
