• 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.

  • Here is an example of some of our exterior design work. We provide layouts for interior and exterior areas. You can see the desire light readings by colors. Each color represents a minumum light range like a bubble around a fixture. We utilize this function to ensure each area is properly lit with the minumum light levels required.
