Two years ago, I wrote a blog recommending for people to think about Lumens, not Watts. In today’s world of higher energy costs and with the release of new our new lighting technology, I am updating this blog for Product Specifiers, Procurement and Finance managers in order to save their business’ even more money.
Just over two years ago the energy rating system for lighting changed from the old A, A+, A++ and A+++ system which had become outdated and frankly too confusing for consumers to understand. So the new “Energy efficiency classes of light sources” came into effect which focuses on the lumens per watt of the light source in order to further reduce energy use.
Why is this important you might ask? Think about MPG on a car. The higher the MPG, the cheaper it is to run a car. The same applies with Lumens per watt and put simply, one luminaire might produce 30,000 lumens and operate at 200W whereas another Luminaire will give the same light output but only consume 150W of power.
Just looking at an energy saving of 50W alone, based on 10 hours use per day at an energy cost of £0.3/kWh will cost 0.15p less to run per day. Equate that to a year that is £54.75 saving. Multiply that by the number of lights across your site, add in some additional presence detection sensors and you are saving a lot of money every year without compromising on anything!
Our Sirius products have always been at the forefront of the market since its first launch back in 2015 when it operated at 120lm/W, The second generation came a two years later at 140lm, the third generation was 150lm/W and currently, our 4th generation now operates at 200lm/W with a light source energy efficiency rating of A. The first LIA endorsed product in the commercial market. The added benefits of this product are not only cheaper energy costs but because of improved thermal management the light output will only degrade by a maximum of 10% over the life of the product compared to 30% on our previous generation.
The world we live in is changing, it is not just about saving energy and reducing our carbon footprint, it is about keeping running costs under control and here at Novah we will help you do just that.
