Light Matters. Delivered Light The Right Way to Measure LED Output Traditional methods of evaluating light focused on lumen output, which was defined by the output capabilities of a light source, such as an incandescent lamp. Manufacturers often make more detailed information available for deeper analysis, creating computer renderings, building mock-ups, and more. Lumen output vs. Delivered light defined Instead of lumen output, the best and most relevant measurement for evaluating LED lighting fixtures is delivered light.
Evaluating delivered light Historically, lighting designers described luminaires by their wattage to serve as the basis for comparison of brightness. How can light be wasted? Delivered Light: How many footcandles do you need? A review of The IESNA lighting Handbook , the page standard reference work from the Illuminating Engineering Society of North America IES , reinforces the importance of delivered light as an appropriate way to measure light, especially for white-light and everyday applications.
Along with chapters that describe in detail how to deliver the right amount of useful light in an application, the Handbook includes an extensive lighting design guide that specifies ideal light levels for every conceivable interior, industrial, outdoor, sports, transportation, and emergency lighting application. The Trouble with Lumens? San Francisco City Hall. New Standards LM — an accepted standard for photometric testing for LED luminaires — fundamentally changed how lighting designers understand photometric measurements and eliminated the need for common light loss factors LLF to be included in calculations.
Confusing Terms Complex, similar-sounding terms, such as luminance and illuminance, make understanding photometrics challenging, and can create confusion when evaluating and understanding the unique properties of LED lighting sources.
Optics Matter Even if two luminaires are measured as providing the same lumens, they may not result in the same illuminance.
Difficult Comparisons Conventional lighting fixture manufacturers often report total lamp lumens more prominently than or instead of total fixture lumens.
Varying Testing and Reporting Many manufacturers still do not provide certified measurements for all luminaire varieties.

Serifed fonts are best for reading on paper, but sans-serif fonts are easier to read on a screen. If you use it, always make it bold, then use color or underlining for emphasis where necessary. Make effective use of figures.
Avoid a presentation that is just text. Such a presentation misses important opportunities to convey information. It is also is wearying to the audience.
Images and visualizations are extremely helpful to your audience. Include diagrams to show how your system works or is put together. Never include generic images, such as clip art, that don't relate directly to your talk. For example, if you have a slide about security, don't use the image of a padlock.
As another example, when describing the problem your work solves, don't use an image of a person sitting at a computer looking frustrated. Just as good pictures and text are better than text alone, text alone is better than text plus bad pictures. When you include a diagram on a slide, ensure that its background is the same color as that of the slide. For example, if your slides have a black background, then do not paste in a diagram with a white background, which is visually distracting, hard to read, and unattractive.
You should invert the diagram so it matches the slide which may require redrawing the diagram , or invert the slide background e. Do not use eye candy such as transition effects, design elements that appear on every slide, or multi-color backgrounds. At best, you will distract the audience from the technical material that you are presenting. At worst, you will alienate the audience by giving them the impression that you are more interested in graphical glitz than in content.
Your slides can be attractive and compelling without being fancy. Make sure that each element on the slides contributes to your message; if it does not, then remove it. Make eye contact with the audience. This draws them in. It also helps you determin when they are confused or have lost interest, and whether your pacing is too fast, too slow, or just right. When giving a presentation, never point at your laptop screen, which the audience cannot see.
Amazingly, I have seen many people do this! Using a laser pointer is fine, but the laser pointer tends to shake, especially if you are nervous, and can be distracting. I prefer to use my hand, because the talk is more dynamic if I stride to the screen and use my whole arm; the pointing is also harder for the audience to miss.
You must touch the screen physically, or come within an inch of it. If you do not touch the screen, most people will just look at the shadow of your finger, which will not be the part of the slide that you are trying to indicate. If you get flustered, don't panic. One approach is to stop and regroup; taking a drink of water is a good way to cover this, so you should have water on hand even if you don't suffer from dry throat. Another approach is to just skip over that material; the audience is unlikely to know that you skipped something.
Think about your goal in giving the talk. When presenting to your own research group, be sure to leave lots of time for discussion and feedback at the end, and to present the material in a way that invites interaction after and perhaps during the talk.
When presenting to your own group, you can perhaps give a bit less introductory material, though it's hard to go wrong with intro material. It should go quickly for that audience; you ensure that everyone is using terms the same way; and it's always good to practice giving the motivation, context, background, and big ideas. For men, this is a dress shirt with slacks or jeans.
For women, I am not qualified to give advice. Some people dress more formally, some more casually. The most important thing is that you are comfortable with your clothing; if you are not, your discomfort will lead to a worse presentation. Answering questions from the audience is very hard! Even after you become very proficient at giving a talk, it will probably take you quite a bit longer to become good at answering questions. So, don't feel bad if that part does not go perfectly, but do work on improving it.
Just as you practice your talk, practice answering questions — both the ones that you can predict, and also unpredictable ones. Giving practice talks to people who are willing to ask such questions can be very helpful.
When an audience member asks a question, it is a good idea to repeat the question, asking the questioner whether you have understood it, before answering the question. This has three benefits.
You will get into more trouble if you try to blather on or to make up an answer on the fly. For an in-class presentation, you will be judged on how well other people understand the material at the end of the class, not on how well you understand the material at the beginning of the class.
You do need to understand the material, but that is not the main point. When you present someone else's paper in class, you should cover not only the technical details people generally do a good job of this , but also what is novel and why others didn't do it before. That is just as important but very often overlooked. Focus on what is important about the paper, not just on what is easy to explain or to give an example for.
Know what your main point is, and don't get bogged down in easier-to-understand but less interesting details. Try not to bring up a topic until you are ready to discuss it in detail — don't bring it up multiple times. Encourage questions — it's the best way to deepen understanding — and be able to answer them. If other students wrote questions in a reading summary, be responsive to them.
When you ask a question, don't assume the answer in the form of your question. Simply put, people who are mediocre at certain things often think they are better than they actually are, and therefore, fail to grow and improve.
Great leaders, on the other hand, are great for a reason — they recognize their weaknesses and seek to get better. The following tips are for business professionals who are already comfortable with giving presentations — and may even be admired for their skills — but who, nonetheless, want to excel. McKinsey is one of the most selective consulting companies in the world, and one I have worked with many times in this area. Senior McKinsey partners have told me that recent MBA hires often try to dazzle clients with their knowledge — and they initially do so by creating massive PowerPoint decks.
New consultants quickly learn, however, that less is much more. One partner instructs his new hires to reduce PowerPoint decks considerably by replacing every 20 slides with only two slides. This is because great writers and speakers are also great editors.
The Gettysburg Address is words, John F. Bullet points are the least effective way to get your point across.
Take Steve Jobs , considered to be one of the most extraordinary presenters of his time. He rarely showed slides with just text and bullets. He used photos and text instead. Experiments in memory and communication find that information delivered in pictures and images is more likely to be remembered than words alone. Speakers who vary the pace, pitch, and volume of their voices are more effective, according to a new research study by Wharton marketing professor, Jonah Berger.
In summary, the research states that effective persuaders modulate their voice, and by doing so, appear to be more confident in their argument. For example, they raise their voice when emphasizing a key message, or they pause after delivering an important point.
