UGR < 19: Verlichting voor optimaal comfort en productiviteit
De Unified Glare Rating (UGR) is een maatstaf voor de mate van lichthinder die een lichtbron veroorzaakt. Hoe lager de UGR-waarde, hoe minder verblinding en ongemak u ervaart. Voor kantoor en educatieve omgevingen wordt een UGR-waarde van lager dan 19 aanbevolen om optimale visuele comfort te garanderen.
De impact van lichthinder op uw gezondheid en productiviteit
Onvoldoende of ongepaste verlichting kan leiden tot verschillende fysieke en mentale klachten, waaronder:
- Hoofdpijn
- Vermoeidheid
- Prikkelende of jeukende ogen
- Korte concentratie
- Verminderde productiviteit
- Een geïrriteerde of chagrijnige gemoedstoestand
De voordelen van verlichting met een lage UGR-waarde:
- Verhoogt het visuele comfort
- Vermindert verblinding en schittering
- Verbetert de concentratie en productiviteit
- Creëert een prettigere werkomgeving
- Kan leiden tot minder hoofdpijn en oogklachten
Verbeter uw werkomgeving met stabiele, flikkervrije LED verlichting
Onze Edge-lit LED panelen worden standaard geleverd met een flikkervrije LED driver. Dit zorgt voor een optimale lichtopbrengst zonder flikkering. Flikkering kan met het blote oog onzichtbaar zijn, maar kan toch leiden tot hoofdpijn, vermoeide ogen en concentratieproblemen.
Hoe werkt een flikkervrije driver?
Een traditionele LED driver zet wisselstroom (AC) om in gelijkstroom (DC) die de LED's nodig hebben. Dit kan echter resulteren in flikkering, die met het blote oog niet altijd zichtbaar is.
Een flikkervrije driver daarentegen maakt gebruik van geavanceerde technologie om de stroom te stabiliseren en flikkering te elimineren. Dit zorgt voor een comfortabele en gezonde lichtomgeving.
Goed voor fotografie en video
De flikkering van LED verlichting is vaak niet met het blote oog waarneembaar. Dit betekent niet dat het er niet is. Met een camera kan je de flikkering wel zien. Flikkervrije LED verlichting is ideaal voor fotografie. Doordat er geen flikkering is, worden er geen vage strepen of andere ongewenste effecten in uw foto's gecreëerd.
Montage van het LED paneel: eenvoudig en flexibel
Dit LED paneel is geschikt voor diverse montagemogelijkheden.
- Systeemplafond: Plaats het paneel eenvoudig in uw systeemplafond met 30x120cm tegels.
- Opbouw: Kies voor een opbouwframe voor een strakke installatie op uw plafond.
- Inbouw: Gebruik bevestigingsklemmen voor een naadloze integratie in uw plafond.
- Ophangen: Met een ophangset kunt u het paneel eenvoudig ophangen waar u wilt.
Tip: Gebruik een opbouwframe i.c.m. de ophangset voor een strakkere afwerking.
Aansluiting
- Direct op stroomnet: De meegeleverde LED driver zorgt voor een directe aansluiting op het stroomnet.
- Stopcontact: Gebruik optioneel een netsnoer om het paneel op een stopcontact aan te sluiten.

Verduurzaam en bespaar met LED panelen
Onze LED panelen zijn een duurzaam alternatief voor traditionele tl-panelen en halogeenlampen. Met een vermogen van slechts 36W verbruiken ze aanzienlijk minder energie, terwijl ze toch een hoge lichtopbrengst van 120 lumen/Watt leveren. Dit maakt ze tot een uiterst efficiënte lichtbron.
De voordelen van LED verlichting
- Energiebesparing: Bespaar tot 70% op uw energiekosten in vergelijking met traditionele verlichting.
- Lange levensduur: LED panelen gaan tot 25 keer langer mee dan tl-panelen.
- Milieuvriendelijk: LED verlichting produceert minder CO2 en is dus beter voor het milieu.
- Helder, flikkervrij licht: LED panelen zorgen voor een heldere en gelijkmatige verlichting zonder flikkering.
- Onderhoudsarm: LED panelen hoeven nauwelijks te worden onderhouden.
Hoeveel LED panelen heb je nodig?
De hoeveelheid LED panelen die je nodig hebt hangt af van de hoogte en grootte van je ruimte.
Bij een hoogte van 2,7 meter verlicht dit paneel ongeveer 8 m². Dus voor een ruimte van 80 m² heb je in principe 10 panelen nodig.
Er zijn nog een paar factoren die je kunt meenemen:
- Gewenste lichtsterkte: Hoeveel licht wil je in de ruimte? Voor kantoorruimtes wordt bijvoorbeeld een lichtsterkte van 500 lux geadviseerd.
- Type LED paneel: De lichtopbrengst van LED panelen kan variëren. Kijk dus goed naar de specificaties van het paneel dat je wilt kopen.
Dimbare LED panelen: kies de perfecte oplossing voor uw behoeften
Wilt u de sfeer in uw ruimte kunnen aanpassen met dimbare LED verlichting?
Onze LED panelen zijn optioneel dimbaar, waardoor u de perfecte lichtsterkte kunt creëren voor elke gelegenheid.
Eenvoudig dimmen met 1-10V of Triac
Kies uit twee dimsystemen:
- 1-10V dimmen: Dit is een gestandaardiseerd dimprotocol dat compatibel is met een breed scala aan dimmers.
- Triac dimmen: Dit is een traditioneel dimsysteem dat compatibel is met de meeste bestaande dimmers.
Tip: Controleer de dimmercapaciteit voor max. aantal panelen
Ervaar de voordelen van edge-lit LED verlichting
Onze edge-lit LED panelen kenmerken zich door een ultraplat design van slechts 11,3 mm. Bij edge-lit LED panelen bevinden de LED chips zich aan de randen van het paneel. Het licht wordt door een speciale diffuserplaat geleid, waardoor het paneel gelijkmatig wordt verlicht.
De voordelen van edge-lit LED panelen
- Dunner design: Doordat de LED chips zich aan de randen bevinden, is er minder ruimte nodig in het paneel. Perfect geschikt voor montage in opbouwframes
- Efficiëntere lichtopbrengst: De diffuserplaat zorgt voor een optimale verdeling van het licht.
- Gelijkmatige verlichting: Geen donkere randen of vlekken.
- Goede warmteafvoer: De aluminium behuizing zorgt voor een optimale koeling van de LED chips.

Highly Recommended
Format: Paperback
Superb book that eased my parental anxieties and has proven very helpful to my college-applicant daughter. Even though it was published in 2011, it is *not* dated (something I worried about). Sure, it will probably need an update by 2020 or so, but most of the info is not very time-sensitive to begin with.

Good place to start
Format: Paperback
I am an independent college adviser based in California and I recommend this book to my clients but only at the very beginning of the process (mostly to the parents of rising high school freshmen and sophomores).
This book is a good place to start especially for many of the foreign educated or immigrant families, who are new to the US College Admission process. The parents do tell us that the book loses its effectiveness once they gain knowledge of the process and/or they begin working one-on-one with an independent and/or become more conscious about meeting the high school counselors early in the process.
I personally like the fact that once this book is overviewed by the families, we can spend more time addressing specific concerns and giving more customized advice. As a result we only need quarterly meetings and these meetings are extremely targeted.
The problem with this book though is it reads like a huge information session by colleges. Those of you who have attended some of the information sessions will know what I mean. The insights provided by the deans and admission officers of various colleges sound somewhat like a "sales pitch" at times and at other times are misleading. I also recommend my students to keep their knowledge up to date by referring to various free resources such as Nancy Griesemer's educational articles in Washington Examiner Online, or the Choice Blog. I spend considerable time volunteering my services at a high school in a mixed/low income neighborhoods; I wish the price had been more reasonable considering that this is a basic book.
Lastly as members of NACAC (National Association of College Admission Counseling), all of us in the admissions field (College Admission Officers, High School Counselors, and Independent Counselors) subscribe to certain codes of ethics and one of the Statements of Good Practice says this about Fairness and Equity: We believe our members have a responsibility to treat one another and students in a fundamentally fair and equitable manner. Unfortunately, Ms. Mamlet and Ms. VanDeVelde do a great disservice by being disrespectful to a large community of Independent College Advisers, many of whom are needed when the high school counselors are juggling with case loads of 200-300 students each and are unable to keep up with the changing scene of college admissions (either due to the lack of funding or time). Gone are the days when people went to some "quack-independents" who promised admissions to Ivy Leagues--sure there are some of those but if families are careful in their research, they will soon find out that these Independents do not belong to any authentic professional organizations such as the NACAC, HECA or IECA. Most students who come to the authentic professionals are motivated to find their right fit college, explore their own strengths and weaknesses and find the best match for their talents, interests and financial situation. Most independents offer services that are reasonably priced. If Ms. Mamlet and VanDeVelde show more commitment to researching folks on the other side of the spectrum, I am sure that their book will be more enlightening.

Best College Info Book Ever!
Format: Paperback
I have read dozens of college-related books in the past 4 years, and this one ranks the highest by far. Written by industry experts and the authors got a lot of top talent to contribute. Full of real-life advice and useful information that is actually true (I fact-checked this against some other info).
I read parts of it out loud to my junior on the plane en route to a college tour, and she actually listened! Humor is always appreciated, and these authors use it without going overboard.
Great information, well-presented. A must-read!

A Must-Read for College (and Even High School) Students
Format: Paperback
First of all, this book really cuts to the point. If you are skilled with skim-reading, you can get this book in about 2 1/2 to 3 hours.
Second, while these strategies are currently untested by me, they seem really practical. Rather than saying "study" or "write paper" or "take test", Dr. Newport lays down specific, useable guidelines for all areas that are intended to cut down on time spent on schoolwork. This helps you with more time to have fun, do extracurricular activities, or work 60 hours a week (like I will soon be doing).
Third, this is THE anti-procrastination book, although I don't get the concept of starting term papers a month before they're due as the examples did. The whole concept behind this book is making sure you've got as little work going as possible that takes as little time as possible. Doing things upfront will ease your load later when the assignments and papers start rolling in and out.
There are only a couple of issues I have with the book.
1) Dr. Newport almost makes the use of personal laptops compulsory in college. I get why it would be such an asset, but for some of us it is more of a liability than an asset. I really believe one can get through college without a laptop at a much smaller personal expense than the costs of buying a laptop/accessories, printer, ink, etc. If you already bought one, that's one thing, but if you haven't, why do you need one? Just use pen/paper and the computer labs' computers and printers. With the printers, odds are you're paying the same amount for 1000 pages that you would for toner (paper is free with the way they price it), and you don't have to drop the cost upfront, but pay as you need the printer. Financially, you're better off skipping the personal printer.
2) He didn't discuss what format to purchase textbooks, but considering he was so insistent on portability, I would probably haphazard a guess that a hard copy is the only way to go. Sure it may be expensive, but what if your Kindle or iPad gets stolen?
Overall, highly, highly recommended. Get this for your child as an early (or very early) graduation present. Teaching them these things will save them a lot of headaches later on.
One last note: This book is not for the lazy. If you aren't willing to do the work, don't expect this book to help. However, if you're someone like me who's sick of lazy and wants to convert, this book IS for you!

One more crappy college study guide
Format: Paperback
When I was taking 4 classes at my local community college, I tried to follow the part of the book that said just to learn math by examples. I ended having to drop the class because at first I was actually ahead of the professor. Then I tried this stupid book's technique of learning by examples and I ended up falling behind. The same can be said of "What smart students know" it's actually a good technique (smart students), but you end up spending hours thinking up questions. Questions can be a part of the process, but it can't be the whole process. I just bought an online course than is way better than both of these combined. It's so good. The point I'm at in the course you can memorize up to 50 items in reverse and forward. You can also tell which place in the list. An example could be
The order of my hallway:
Dog = front door
Cat = wall
Duck = light switch
Printer = holder
Hitler = chair
MAO = rug
Goku = ceiling light
Kurrin = mirror
Gohan = heater
Frieza = painting
You would then connect / visualize each word / picture with a part of your house. The rule is to visualize each for only 6 seconds while recalling can only take 6 seconds. If you miss one you have to do the six second process again until you make no mistakes.
P.S. I'm not telling anyone the name of the course or where to buy it. I want to be ahead of all other students.
Edit: I'm back in college taking two college level courses. While I don't agree with everything in this book (I have to re-read it) I agree with 80-85% of the methods used in this book that I remember. Such as not doing the reading he was right. I haven't done the reading in my psychology 101 class and have only focused on taking / memorizing / learning the notes and while I haven't gotten a grade yet, I actually feel I'm learning enough and today in class I note notes from a documentary we watched. The professor said to do the reading for chapter 2 of the textbook. I'm not even going to do it. I'm going to just take notes in class then go over the reading. I did this for my 1st set of notes and I didn't understand something in the lecture notes. I ended up re-reading that / part / example [it was on the scientific method].
I remember from taking my developmental math class that the professor was actually doing examples (even though I couldn't figure out from what part of the book they were from and / or I couldn't write every example like he said) If I had just asked questions and either watched videos on Youtube I would've probably remembered the material from that class.
I'll do another edit once I'm done with classes. I'm also going to write / provide a list of books that I think are good for learning and have good advice for college.
Edit: I ended up trying to do the advice from this book and if I didn't look up the answers for the test for my psychology class I wouldn't be in college today. I'm not saying that all of this book is bad but I went from thinking that 85% of it is good to now thinking that 50% of this book is good. The other half is crap. Such as the technique for Q/E/C he doesn't give any examples or enough examples. The other advice like making your own problem sets I wouldn't have thought of. Even though this is an all right technique your wasting time because you can just practice doing other peoples problems (like those online or from a professor) or do Bullet point concept from another book I read (I'm going to provide a list once I'm done with this review). The one technique that is very good is the lecture technique he mentions in the book. For some reason, this technique helps with putting material into memory. His section on writing papers is also very good. His explanation on how to prepare for and take exams is also good. Also, he should have made the book more visual and put actual writing from actual students other than that it's an all right book.
Here's the list of books I've read (so far) that will most likely get you A's
College Rules
https://www.amazon.com/College-Rules-4th-Survive-Succeed/dp/1607748525/ref=sr_1_1?s=books&ie=UTF8&qid=1530133408&sr=1-1&keywords=college+rules
Guaranteed 4.0
https://www.amazon.com/Guaranteed-Follow-3-Step-Plan-Dont/dp/0974264806/ref=sr_1_1?s=books&ie=UTF8&qid=1530134451&sr=1-1&keywords=guranteed+4.0
How to study in college
https://www.amazon.com/How-Study-College-Walter-Pauk/dp/1133960782/ref=sr_1_4?s=books&ie=UTF8&qid=1530134633&sr=1-4&keywords=how+to+study+in+college
The only book I've read from cover to cover is GT 4.0 it's probably the best in my opinion because the system in this book will get you A's. The only reason last semester I didn't get A's was because I didn't follow the system to the t. If you follow the GT 4.0 system to a t and don't get all A's she'll give you $100.
Hope this helps.
Edit 2020:
From what I remember reading this book, this applies to college level courses and even at the same time I tried using his question / evidence technique while taking a psy101 class and couldn't do it. Also he's right to a very large degree about living off of lecture notes. Living off of the lecture notes IMHO can only be done if it's a science science class or a college level math class. I'm currently taking a pre-req class and the professor explains everything. Along with the Guaranteed 4.0 technique this is a pretty decent book.
