Lighting Audit Q & A

Lighting is something that is taken for granted in most working environments.  We turn lights on everyday to see what we’re doing and as long as they turn on then they are quickly forgotten about.  Because we work under these lights day in and day out we don’t notice the changes that take place with them.  These changes are decreased light output due to lamp lumen depreciation which leads to eye strain and headaches, as well as subtle flickering and humming that also leads to headaches and poor work performance.  If your lighting system hasn’t had a makeover in the past 5-10 years then it’s time for a lighting audit to show you what improvements can be made and how they will be beneficial.


The following are some frequently asked questions about lighting audits:


Q - What exactly is a lighting audit?
A – We will do a walkthrough of your facility and note all of your existing lighting by area, noting how they are performing, controlled, and how long they are used each day.  We then create a proposed system and compare the benefits against your existing system in terms of energy savings, maintenance cost savings and return on investment.


Q – What kind of energy savings can be had from a lighting conversion?
A – Common energy reductions will range from 40 to over 70%.  With lighting generally accounting for at least half of your electrical bill, these savings can often add up very quickly.


Q – I don’t like fluorescent lighting, what will this get replaced with?
A – Either T8 or T5 fluorescent most likely, however, LED lighting is being used more and more everyday.  The hate for fluorescent lighting is based on the old T12 fluorescent technology which had horrible colour rendering abilities, flickering light and humming ballasts.  All of these issues lead to eye strain, headaches and generally poor working environments.  New T8 and T5 fluorescent lighting does not have these issues.  In all cases where we convert T12 to T8 or T5, employee response is always favourable.  LED lighting offers the same creature comforts but with further energy reductions and superior life expectancy.


Q –What kind of return on investment can I expect from a lighting conversion?
A – This depends on quite a number of factors but most conversions will see a return on investment in 2 – 4 years on average.  Many retail stores that use large quantities of halogen track lighting will often see an ROI in as little as 6 months when converting to LED lamps.


Q – Are there any government rebate programs available for lighting conversions?
A – In most cases, yes.  BC Hydro has their Power Smart Program which generally applies to all business types that are serviced by BC Hydro.  Rebate values vary depending on account type and lighting configurations.


Q – How long does it take to have a lighting audit done?
A – The initial walkthrough typically takes anywhere from 10 minutes to over an hour, this depends on the size of the facility and how complex the lighting system is.  From there we strive to have a detailed audit completed and ready to present to you in a week or less.


Q – What does it cost to have a lighting audit completed?
A – There is no cost for the audit itself.  We complete audits as a sales tool to prove the value of a lighting conversion to our clients.  Our goal is to drum up projects for ourselves which in turn gives us an income while at the same time reduces your operating costs which will increase your income.
