This past January, EISA brought us the final phase out of 60-watt incandescent bulbs. But two years ago, the phase out program removed some halogen PAR lamps, T12 linear fluorescent lamps, as well as some less popular 2-ft. and 4-ft. T8s. The T8 700 series fluorescent lamps were just shy of the chopping block on the previous phase out, but were given a two-year extension. On July 14th, 2014, all T8 700 series fluorescent lamps will fail to meet the new minimum energy ratings and will no longer be produced. The new ratings increased the minimum allowable values for lumen efficacy (lumens-per-watt), wattage, and minimum color rendering for each lamp. The 700 series of fluorescent T8s has terrible color rendering (averaging in the low 70s) while the newer 800 and 900 series of lamps deliver more vibrant color saturation at CRI levels of 80-85.
Grace Kelly and James Stewart in Rear Window
Have you ever wondered why actors have a stunning appearance in movies? Yes, they get airbrush make-up and the concept of photoshop does exist in the world, but the reality is; it is all about the lighting! Since the earliest movies, lighting has always been an essential part in film making with advances in lighting technology making all the difference.
In the Beginning: They Stayed Outside
In the late 1800s, film makers had not acknowledged the use of artificial lighting in film. The standard was to shoot during the day in a set that had either, an open roof or a glass ceiling. While natural light is the best light source, this methodology put a hindrance on filming anything at night or indoors; therefore, by the early 1900s, artificial light sources came into play.
In the 20th Century: Grace Kelly was Glowing
The main source of artificial lighting in film at that time was arc bulbs, the predecessor to HID bulbs. Used with a reflector, the bulbs created a bright light and allowed for directional lighting, enhancing parts of the set that needed to be highlighted. These lights also made for good spotlights, casting a brighter light on one side of the actor’s face (key light), and a softer light on the opposite side (fill light), to eliminate unflattering shadows. A third back light would be used to create the effect of a halo around the actor’s head. In the 1920s, incandescent bulbs started to become a growing sensation in studio lighting, as they produced a better color temperature, required less electrical and man power, and did not emit the humming sound the HID bulbs did.
In the Present Day: Lighting Comes in Various Forms
Today, there are so many new lighting technologies, all of which get used on film sets today. We’ve already covered HID and incandescent, but many of the other forms include halogen and xenon lamps, fluorescents, LEDs, and HMI bulbs, a technology coined by OSRAM SYLVANIA. Generally used with ballasts, the film-specific HMI bulbs are very popular bulbs used in the film industry, winning OSRAM an Oscar in 1987 and a Primetime Emmy Engineering Award in 2007.
Fun Fact: On movie sets, mashed potatoes replaced ice cream in sundaes as the ice cream would melt quickly, due to the lighting.
DIY Lighting Kit for Home Movies
Make your own film light kit! You need these items:
- Broom Stick or Mic Stand (the mic stand does have support at the bottom)
- LED or Incandescent Bulb
- Wax Paper (optional)
- White or Light Poster Board (optional)
Insert the bulb into the reflector and attach the reflector to your stand of choice. It’s that simple! Use the wax paper to diffuse (soften) the light if needed. For added reflection, place the poster board where it is needed.

Introducing Light Post, a bi-weekly gathering of lighting innovations and of course, news. So make sure you swing by every other week for your dose of Light Post.
Wake Forest Introduces Revolutionary Fluorescent Bulb
Physics professor David Carroll and his team of researchers at Wake Forest University have created a fluorescent bulb set to replace LEDs and standard fluorescents. These new bulbs, based on field-induced polymer electroluminescent (try saying that fives times in a row) technology, or FIPEL, are shatterproof, flicker-free, and won’t burn out. No more of the mosquito-in-your-ear humming noise many office workers complain about now. Besides no more humming, these lights give off a soft, white light and are extremely efficient, at least twice as efficient as compact fluorescent bulbs (CFL). Better yet, these lights are long-lasting: Carroll has one that has worked for about a decade. These lights should be available to consumers as early as next year.
Rockefeller Center Christmas Tree Lighting not Hampered by Hurricane Sandy
Hurricane Sandy definitely left a dark spot over New York City, flooding pretty much everything, costing millions of dollars, and leaving lots of people without power. However, the Rockefeller Christmas Tree Lighting erased any dark spot cast by the superstorm. The massive 80-foot Norway spruce, complete with 30,000 lights and topped with a Swarovski star, came to life November 28. The 10-ton tree resided at the Mount Olive, N.J. home of Joe Balku and was a mere 22-feet tall in 1973 when Balku bought the house. Today, the tree measures about 50 feet in diameter. The iconic tree will remain in the public eye until January 7.
After that, it will be turned into lumber for Habitat for Humanity.
Streetlights in Central London to be Controlled by iPads
If this isn’t evidence of technology becoming more and more important in our everyday lives, I don’t know what is. Westminster City Council announced it will be replacing about 14,000 central London street lights with new, iPad controlled smart lights. The iPad application will be able to monitor street lighting levels and reliability, monitor which lights are not working properly, and can even predict when a light will fail. Installation of the new lights will cost about $3 million, but it will save taxpayers hundreds of thousands a year.
Texas Towns and Parks Scale Back Lighting to See Stars
Having recently moved from a small, Texas town to the big city, I can certainly attest for the lack of star-gazing ability here in the Metroplex. That’s why many Texas towns and state parks are fighting light pollution. In recent years, Texas’ state parks have seen a decline in visitors and to lure them back, the parks are promoting chances for night-sky viewing, away from the city lights by advocating cities and towns to use down-facing light fixtures, so as not to pollute neighboring areas with unnecessary light.
LED Lights May Boost Milk Production in Cows
There may be a link between higher milk production and LED lights. An initial experiment done in 2010 at Oklahoma State University found a 6% increase in milk production in cows when traditional lights were replaced with LEDs, which consume at least 75% less energy than conventional incandescent bulbs, in areas where cows were housed. While the research is still underway, and if the results can be replicated in other institutions, not only will cows produce more milk, but the savings over the long run will be tremendous for farmers.

Halogen, Xenon, Fluorescent, or LED: What is the best type of under cabinet lighting? If you’ve ever asked yourself that question, you were asking the wrong question. There is no “good, better, best” with under cabinet lights. Choosing the right light is a matter of personal preference, and it depends on how much you value dimming, heat reduction, color accuracy, and energy savings.
Xenon Light Bulb
Xenon under cabinet lights are an update of older Halogen lights. Halogen under cabinet lights, especially the light “pucks” you see in hardware stores, are cheap and provide perfect color accuracy (color rendering index), but they use tons of energy and waste most of it as heat. Xenon keeps the benefits of Halogen, but burns brighter and cooler. Their color rendering makes granite countertops or trinkets in display cabinets look their absolute best, and because they are brighter than Halogens, Xenon bulbs save energy by using fewer watts than a Halogen bulb.
Fluorescent under cabinet lights are a great choice for bright, energy-efficient lighting that burns cool. They’re a popular choice in kitchen cabinets and pantries because they don’t add extra heat to their surroundings, which can increase the likelihood of food spoilage. Unfortunately, there are a number of trade-offs. Fluorescent lights have relatively poor color rendering — 80 CRI to Xenon’s 100 CRI — so they distort colors and make granite and marble countertops and backsplashes appear washed out. Furthermore, while they use much less energy than Halogen or even Xenon, they are not dimmable and some models are slow to reach full brightness.
LED Under Cabinet Light
LED is the newest, most energy saving option for under cabinet lighting. To many, LED under cabinet lights are the perfect option. Unlike fluorescent, they are instant on and many models are dimmable. Unlike Halogen and Xenon, they also create very little heat. However, they do have two drawbacks: Color rendering and cost. Like fluorescent lights, their CRI is in the 80-90 range, so they aren’t the best choice when color accuracy is highly valued. They also have the highest up-front cost of any under cabinet choice. On the other hand, they will save the most in the long-term. LEDs use only a fraction of the energy consumed by other types of under cabinet lights. Even better, they last 20,000 to 60,000 hours, so you’ll never have to replace them and will save on bulb replacement costs.
Again, your choice of under cabinet lights will depend on your specific needs. In general, however, if you prize color accuracy and don’t mind the heat, choose Xenon, but if you prefer energy savings and cool operation, go with fluorescent or LED. Of course, that’s only what we think. Let us know which under cabinet lighting option you prefer in the comments, or drop us a line on Facebook, Twitter, or Google Plus.

If you read last week’s article, you learned about the mercury content in compact fluorescents and just how much of a threat it can be to your health. However, you were probably left with this question: If a CFL in your home breaks, what do you do? You don’t need to call a hazmat team, but you will need to follow these 4 tips for your safety:
1. Don’t Panic
First, don’t panic. As noted in the previous article, your exposure to mercury from a broken CFL is less than that in a tuna sandwich. Though the danger of mercury exposure is minimal, use common sense: Get everyone out of the room and make sure they don’t step on the glass.
2. Close Off the Room
Next, close off the room and open the windows to let any mercury vapors ventilate. It’s also a good idea to turn off your HVAC system to avoid circulating the vapors throughout your home. The room should be safe to re-enter after about 10 minutes*.
3. Collect the Debris
Upon returning to the room, collect the debris, including broken glass, powder, and plastic from the broken lamp. Do this by scooping up the broken pieces with a stiff piece of paper. Use the sticky side of a piece of duct tape to pick up any smaller pieces remaining on the floor or stuck in carpet fibers. However, do not use a vacuum cleaner, which could excite the mercury on the floor and release it into the air.
4. Recycle or Dispose
Finally, place all materials in a sealable container such as a jar or pack it within two zipper bags. Dispose of the CFL and its container according to laws in your area. Though most areas allow CFLs to be disposed of in the garbage, the best way to dispose of a CFL, broken or intact, is by recycling. The process is simple, inexpensive, and in some areas, it’s even free. To find a recycling location near you, go to Earth911.com. For added convenience, you may prefer a postage-paid CFL recycling kit from Veolia.
