 Warehouse Applications for LED Lighting

Lighting needs are responsible for nearly half to three quarters of a warehouse facility’s lighting needs. Lighting was long considered an area in which costs were difficult to control. One possible solution was to call the lighting contractor every couple of years to replace old inefficient fixtures. Now with LED lighting technology this circle is all set to change – after all the technology delivers 80% plus direct energy savings over incandescent technology and will continue to be in service for over 50,000 hours or equivalent to 18 plus years based on normal 10 hour per day use.

A warehouse needs to provide adequate light bulbs to help in identifying workers and goods alike, as well as for safety reasons to reduce the risk of accidents and help in navigating aisles. Different areas of the warehouse are used for different purposes and these areas may have varied lighting needs. A warehouse need not be a dark, dull and depressing area. With the right lighting technology, such as LED High Bay Lights  it can be a comfortable and safe for all workers.

Cost of Lighting a Warehouse

The cost of lighting a warehouse is about $ 1 per square foot per year. Using the very latest of efficient LED lights (110-120 LM/W)  the overall energy consumption can be reduced between 50 to 90%. For a 200,000 square foot storage facility lighting costs can fall from $ 200,000 per  year to as low as $ 20,000.  Coupling add on features as dimming controls and  instant on with intelligent lighting control systems the warehouse retrofitted with new LED lights can further reduce lighting costs to $ 10,000. Light Emitting Diode based lights are solid state lights and are not affected by on-off cycling. This make LED  Lights perfect for pairing with intelligent lighting control systems that provide real time, dynamic lighting level control. 

Designing LED Lighting for Warehouses

Overhead lights are needed in loading areas for general illumination for better safety during loading.  It is important to determine the lighting needs in each area and design lights accordingly.  In most cases an actual field illumination test needs to be performed before the change to LED is confirmed.

Also remember that overtime MH, HID bulbs will reduce in the amount of light they give off.  In 5 years the old lights can reduce in intensity over 30%.  The advantage with LED lights is that on an average they will only reduce 1-2% per year.

Recommended horizontal lighting levels range between 100 LM for inactive areas to as high as 500 LM in high activity areas where small items are handled. Good vertical illumination is needed to enable employees read labels. In general for an area that needs 100 LM  of horizontal illumination  Thus with an average illumination of 300 LM the minimum illumination should be 100 LM . The Illuminating Engineering Society of North America (IESNA) prescribes a set of guidelines for safe and comfortable lighting levels in warehouse facilities.

Lighting Options for Warehouses

When choosing the right lighting technology for warehouses a number of factors need to be considered.

Life time cost of lighting – These include onetime cost of powering the lights, set up costs, replacement costs,  cost of safe disposal of bulbs, cost of ordering and storage of replacement bulbs. If a warehouse believes in offsetting its carbon foot print  as a socially responsible benefit then this must also be factored in. Some experts believe that in keeping with the triple bottom line approach to business, other environmental and social costs of lighting should also be calculated. Considering all factors, LED lighting trumps the competition.

Cost of replacements

LED lights have a phenomenally long life. Each LED device can last up to 20 years or more. Businesses relying on alternate lighting devices will need 1-0 incandescent bulbs or 24 CFLs for a single light bulb fixture during the same period.

Cost savings in maintenance

Here is the cost of replacement for a single light fixture




Time in minutes


Staff documents light failure and places a call to maintenance personnel



Logging the call and scheduling



Arranging replacement lamp and ladder



Reach location of light failure and Replace lamp



Dispose burnt out lamp, replace equipment and log details



Total time taken

45 minutes

At an average labor cost of $ 18 per hour each replacement would cost $15. If an outdoor light needs replacement the cost will be higher as a truck or special ladder may be needed to access lighting fixtures and more than one personnel may be involved.

Clearly the long life of lights is an important component of the total cost of ownership. The annual replacement costs for incandescent will reach $ 60 per year while the same figure for fluorescent fixtures  will be $12.
