Light Globe Replacement
At United Electrical Services we can expertly relamp your light fittings to ensure your lights are operating brightly and providing the light output desired. When we relamp, we clean the diffuser or lens and reflective surfaces to ensure you are maximising your light output. We can relamp any type of lamp or globe.
There are two types of re-lamping.
Spot Re-lamping
Replacing lamps and globes one by one as the lamps burn
out.
Group Re-lamping
Replacing lamps and globes in bulk at a predetermined
interval based on the average rated life, hours of use and
lamp lumen depreciation. Group relamping has proven to be
industry best practice.
In commercial applications we recommend group re-lamping.
Group re-lamping has proven to offer large savings in both
time and labour costs over spot re-lamping of failed
lights.Lumen depreciation, color shift over life and cost reduction are the
main reasons that a user should consider a group relamping program. When a lighting
installation is new, the light level is high and the quality of the light is excellent.
Over life, lamps suffer a decrease in efficacy (lumens per watt) caused by both the loss
of the light producing chemicals within the arc tube and darkening of the inner walls of
standard arc tubes. Most metal halide lamps will decrease to around 60% of initial rated
light output at about half of rated life.
