Group relamping is a process that saves money when fluorescent, high-pressure sodium or metal halide lighting is used. All lamps in a group are replaced at the same time rather than one at a time on failure. Using group relamping has been found to reduce relamping costs by 50%. Whether your staff does group relamping or you ask Service Lamp to provide the service, group relamping is a cost-effective way to keep your lighting in top shape.

Why Group Relamping Works

You know from experience that incandescent lamps fail at random. Service life for bulbs is an average so half the bulbs will fail before the service life stated on the package. Incandescent lamps can fail at random and far short of the average because of the filament. Physical shock or vibration for example will cause a lamp failure. Power spikes can also dramatically shorten the bulbs life.

High intensity discharge lamps and fluorescent lamps, do not use a filament to generate light. The processes used to generate light are predictable such that most lamps will need to be replaced near the end of their rated life. Ballasted lamps are perfect candidates for group relamping.

The predictability of this class of lamps also enables us to project lumen depreciation. Lumen depreciation simply means that an old lamp is not as bright as a new lamp. Over time the business still pays 100% for electricity but may only get 30% of the light output from a depreciated metal halide lamp. Lower light levels due to lumen depreciation or dirt accumulating on the lamp or fixture are important considerations for group relamping.

Another consideration for group relamping is the effort required to change a lamp. This type of lighting is generally high above the floor. On the retail sales floor merchandise needs to be moved to change a lamp. Changing bulbs during work hours in offices or production areas means disrupting work flow. Service Lamp can arrange for group relamping to take place overnight with zero production or sales lost.

How Group Relamping Works

Group relamping means replacing all light bulbs at one time completely or in an area of the a store or warehouse. The advantage of group relamping is about a 50% savings in labor costs when compared to replacing lamps on failure. There are other tasks performed during group relamping that are common sense aspects of facility management.

The other advantage of group relamping is that it is easier to meet storage and handling requirements for ballasts and spent lamps containing mercury. Lighting products replaced during the group relamping process are removed by our service or can be shipped to the recycler immediate after removal. Spot replacement generally accumulates spent lighting product over a long time.

Service Lamp can meet your group relamping needs by providing quality lighting products to your maintenance department or a complete package including labor. Qualified technicians and electricians will be dispatched to your property with all the materials necessary to complete the job. Typically an entire property can be done overnight and ready to open the next morning.
