- Dear Fellow Wood Finisher, In Marty Schlosser's previous post, he covered why LED woodshop lighting is so popular today... And how to convert your shop over to LED if you're in the market to do so. Today, he's discussing what is arguably the MOST important aspect of any LED woodshop lighting consideration... How to get the right brightness and color accuracy.
- One of our customers wrote a nice article on some recently installed lights purchased from our website. Take a look and see the perfectly lit workshop space. If you have any articles of work you've done with our products or services feel free to share with us. You can visit their website here to view the full article
- Save On Energy has been around for quite some time now, saving millions of dollars by reducing energy costs for consumers and businesses along with making the overall cost associated with upgrades much easier to obtain. Rebate programs have changed quite a bit over the years and still remain active in 2021. The three main categories are; Retrofitting, Small Business Lighting and Energy Consulting programs. Most business will be covered by this program as it’s where the big savings reside. The requirements are broad and cover almost every business that could save money by replacing old technology in lighting and HVAC redesign. Keep in mind you must have preapproval and the incentive amount must exceed $500. Here is a full list of incentives offered. https://saveonenergy.ca/en/For-Business-and-Industry/Programs-and-incentives/Retrofit-Program/Retrofit-Program-Update Many small businesses were having a difficult time meeting the retrofit requirements and or the incentive just wasn’t enough to warrant the paperwork and as a result the Small Business Lighting program sprung to life. This program is a unique program designed for businesses with fewer than 50 employees offering a total savings of 2000 on lighting. The only caveat is the lighting must be from a list of energy efficient products and previous submissions between 2016-2019 are not eligible to participate again. Now keep in mind, you may only be covered by a portion of that set amount and in on some special circumstances the incentive can exceed 2000 dollars. This includes materials and labour as well. Along with much of the above, it’s difficult to decide what program is best for anyone. The third program consists of help and services aimed at making the entire process smoother with assistance from experts in the field. Knowing your way around the process has been and will remain the most difficult part of any of these programs. With red tape all over you need to know where to submit, what to buy and so much more. At LED Lighting & Electrical Distributor we are your experts. We provide energy efficient lighting that qualifies, and also have the team of experts whom can design and facilitate the entire process from start to finish. If you’re looking at improving your lighting at home or your office simply give us a call and we can get the ball rolling. The sooner you replace inefficient lighting the sooner the costs and savings will start.
- A common issue we encounter when doing layouts is how to accurately measure the reflectance in a building. The reflectivity of any surface is calculated by a numerical value 0.0 behind jet black(no reflectance) and 1.0 being as white(full reflectivity). It does not go beyond these values. Typical default values are 0.8(ceiling) 0.5(walls) 0.2(floor) which is like a dark grey concrete floor. The ceiling plays a very smaller role in boosting the overall lighting while the floor and walls are the most crucial. It makes a big deal to change this value when it is appropriate. One of the easiest ways to figure out the reflectance is to take a picture of the inside of a building and convert to it a black and white photo or better known as gray scale. This value is a perfect representation of your reflectance and is perfectly acceptable in all cases. Many programs will allow you to color pic and insert these values into the programs used to design lighting projects. Simply find that value(RGB, or HEX) and place it over. Try and include the floor and walls if possible, take several pictures if you can't get it all in. A nice shiny floor in a retail shop can up the default value to .6 in some stores, that is going to amplify your lighting tremendously. A warehouse is typically concrete and very dirty. We often find these layouts require nothing more then a design using your default reflectance. However, in some concrete flooring could be painted white to help with lighting, in this case adjust your floor reflectance accordingly. If you want to be able to easily pic colors. Try this cool program that allows you to hover over anything on your computer and at the click of a key it will grab the color under your mouse. A handy tool for selecting colors. https://colorpix.en.softonic.com/
- Light Loss Factor or also known as LLF in short form is one of the hardest parts to remember in the lighting industry. Each fixture can have a different value and some are better designed to eliminate some of the common losses we encounter when doing a lighting design. Each manufaturer of fixture, or lamp would have it's own value to be totally accurate. The IES files provided to not include such light reductions so experience in this field is mandatory. For example, a fluorescent fixture needs to be roughly around 0.7 to 0.8 LLF total which should include reductions due to ambient room temperature and ballast factor if it was not done already on an IES file. Some parts may be already done in the IES file so that makes having tools to read these files extremely important. LED's have come a long way and have far less light loss. Dirt and Dust play a part still as they'll always interfere with light output. We typically do not measure a design with dust and dirt in it so we leave that out. For LED we typically reduce the LLF to .95 or by 5% to simply add a little fudge factor to a layout. It's always better to have a little more light in a layout to be safe. Did you know we do lighting layouts? Using the latest technologies we can provide indoor and outdoor lighting. Many of our existing clients use this information as a sales tool and also a tool to gauge in either desired quantities and/or light levels. Using IES files and following lighting guidelines we can produce a near perfect 3D rendering for any project. Contact us to inquire about how we can produce a report for your next project.
- In Canada we typically use FC(foot-candles). But on the odd occasion a Canadian company comes to us with a lux reading and prefer the layout done in that measurement. More often for the US we use lux but FC has been requested. Either way the difference is easily calculated by: 1FC = 10 Lux note: 0.0929030436 = 1 Lux to be exact. Lux definition: A unit of illuminance equal to 1 lumen per square meter. FC definition: A unit of measurement for the density of light as it reaches a surface. One foot-candle is equal to 1 lumen per square foot.
- The Save on Energy programs will be continuing into 2024. The new framework will be released in November 2020 and will take effect on January 4, 2021. This means that retrofit rebates for lighting upgrades will still be around but the amount received will be lowered. Applications under the current rates must be approved by December 31, 2020. NRG Alternatives has successfully gotten our clients rebates for over 300 retrofit projects. Call us today for your free quote!
- Here is an example of some of our exterior design work. We provide layouts for interior and exterior areas. You can see the desired light readings by colors. Each color represents a minimum light range, like a bubble around a fixture. We utilize this function to ensure each area is properly lit with the minimum light levels required.
