The Powerful Next Step for Lighting Retrofits
It’s 2015. You’ve already changed halogen lamps to LEDs. What’s next?
LED technology has evolved. It’s now possible to change ceramic metal halide (CMH) lamps and fluorescent tubes to LED – with a decent payback.
On top of energy savings, an upgrade to LEDs delivers savings on avoided maintenance costs. Your best practices for CMH and fluorescents likely include regular group relamping based on burn hours to keep light at proper levels. With LED technology that lasts 50,000 hours, you may not need to change LED lamps for several years.
So – why is now the time to transition CMH and fluorescents to LEDs?
Haitz’s Law is at work here – there’s been “an exponential increase in lumen output from packaged LEDs and a corresponding reduction in dollar per lumen.” In other words, more light output at an ever-dropping cost.
The acquisition cost of sensors and control systems (both wired and wireless) has dropped too, making controls retrofits more affordable. The sheer volume of efficiency-focused purchases is pushing the cost down further and further. It doesn’t hurt that utility incentives strongly encourage upgrades, either.
As you’re conducting a group relamping or retrofit, it’s a good time to consider the overall lighting design. Work with a lighting professional to evaluate whether the lighting design can be improved in addition to energy efficiency. [In our experience, a switch to the right lights can have numerous benefits.]
If you consider the drop in technology costs along with energy savings, avoided maintenance, and rebates – the ROI on WB’s LED and controls upgrades is often less than 2 years.
